PROSPECTUS SUMMARY

This summary highlights information contained elsewhere in this prospectus. It does not contain all of the information you should consider before making an investment decision. Before you decide to invest in our securities, you should read the entire prospectus carefully, including the risk factors and financial statements and related notes included or incorporated by reference herein and therein.

Partnership Overview

The Partnership was formed in 1998 for the primary purpose of acquiring a portfolio of mortgage revenue bonds (“MRBs”) that are issued by state and local housing authorities to provide construction and/or permanent financing for affordable multifamily housing, seniors housing and commercial properties. We also invest in governmental issuer loans (“GILs”), which are similar to MRBs, to provide construction financing for affordable multifamily properties. We expect and believe the interest received on our MRBs and GILs is excludable from gross income for federal income tax purposes. We also invest in other types of securities that may or may not be secured by real estate and may make property loans to multifamily properties which may or may not be financed by MRBs or GILs held by us and may or may not be secured by real estate. We expect that a majority of all assets held by us are and will continue to be considered eligible for regulatory credit under the Community Reinvestment Act of 1977 (the “CRA”).

We also make noncontrolling equity investments in unconsolidated entities for the construction, stabilization, and ultimate sale of market-rate multifamily properties (“JV Equity Investments”). We are entitled to distributions if, and when, cash is available for distribution either through normal operations, a refinance, or a sale of the property. In addition, we may acquire and hold interests in multifamily, student and senior citizen residential properties (“MF Properties”) until the “highest and best use” can be determined by management.

The conduct of the Partnership’s business and affairs is governed by the Partnership’s Second Amended and Restated Agreement of Limited Partnership dated December 5, 2022, as amended pursuant to a First Amendment to Second Amended and Restated Agreement of Limited Partnership dated June 6, 2023 (as amended, the “Partnership Agreement”). Our sole general partner is America First Capital Associates Limited Partnership Two (“AFCA 2” or the “General Partner”). The general partner of AFCA 2 is Greystone AF Manager LLC (“Greystone Manager”), which is an affiliate of Greystone & Co. II LLC (“Greystone & Co.”). Greystone & Co., together with its affiliated companies (collectively “Greystone”), is a real estate lending, investment, and advisory company with an established reputation as a leader in multifamily and healthcare finance, having ranked as a top Federal Housing Administration (“FHA”), Federal National Mortgage Association (“Fannie Mae”), and Federal Home Loan Mortgage Corporation (“Freddie Mac”) lender in these sectors.

The Partnership has issued Beneficial Unit Certificates (“BUCs”) representing assigned limited partnership interests to investors (“BUC holders”). Our BUCs are traded on the New York Stock Exchange (“NYSE”) under the symbol “GHI.” The Partnership has designated three series of non-cumulative, non-voting, non-convertible preferred units (collectively, the “Preferred Units”) that represent limited partnership interests in the Partnership consisting of the Series A Preferred Units, the Series A-1 Preferred Units representing limited partnership interests (“Series A-1 Preferred Units”), and the Series B Preferred Units. There are currently no Series B Preferred Units issued and outstanding. The holders of the BUCs and Preferred Units are referred to herein as “Unitholders.” Our Unitholders will incur tax liability if any interest earned on our MRBs or GILs is determined to be taxable, for gains related to our MRBs or GILs and for income and gains related to our taxable investments such as our investments in unconsolidated entities and property loans.

The Partnership has been in operation since 1998 and will continue in existence until dissolved in accordance with the terms of the Partnership Agreement. Our principal executive office is located at 14301 FNB Parkway, Suite 211, Omaha, NE, 68154, and our telephone number is (402) 952-1235.

We maintain a website at http://www.ghiinvestors.com, where certain information about us is available. The information found on, or accessible through, our website is not incorporated into, and does not form a part of, this prospectus or any other report or document we file with or furnish to the SEC.

Our Business Objectives and Strategy

Investment Strategy

4

Our primary business objective is to manage our portfolio of investment to achieve the following:

We are pursuing a strategy of acquiring additional MRBs, GILs and other investments on a leveraged basis to achieve our objective, as permitted by our Partnership Agreement. In allocating our capital and executing our strategy, we seek to balance the risks of owning specific investments with the earnings opportunity on the investment.

The Partnership believes there continues to be a significant unmet demand for affordable multifamily and seniors residential housing in the United States. Government programs that provide direct rental support to residents have not kept up with demand. Therefore, investment programs that promote private sector development and support for affordable housing through MRBs, GILs, tax credits and grant funding to developers, have become more prominent. The types of MRBs and GILs in which we invest offer developers of affordable multifamily housing a low-cost source of construction and/or permanent debt financing. We plan to continue investing in additional MRBs and GILs issued to finance affordable multifamily and seniors residential rental housing properties.

We continue to evaluate opportunities for MRB investments to fund seniors housing properties and/or skilled nursing properties issued as private activity or 501(c)(3) bonds similar in legal structure to those issued for traditional affordable multifamily housing properties. We will continue to leverage the expertise of Greystone and its affiliates and other reputable third parties in evaluating independent living, assisted living, memory care and skilled nursing properties prior to our MRB acquisitions. During 2021, we acquired our first senior citizen housing MRB, Meadow Valley, that will finance the construction and stabilization of a combined independent living, assisted living and memory care facility in Traverse City, MI.

We continually assess opportunities to expand and/or reposition our existing portfolio of MRBs, GILs and other investments. Our principal objective is to improve the quality and performance of our portfolio of MRBs, GILs and other investments with the intent to ultimately increase the amount of cash available for distribution to our Unitholders. In certain circumstances, we may allow the borrowers of our MRBs to redeem the MRBs prior to the final maturity date. Such MRB redemptions will usually require a sale or refinancing of the underlying property. We may also elect to sell MRBs that have experienced significant appreciation in value. In other cases, we may elect to sell MRBs on properties that are in stagnant or declining real estate markets. The proceeds received from these transactions would be redeployed into other investments consistent with our investment objectives. We anticipate holding our GILs until maturity as the terms are typically for two to four years and have defined forward purchase commitments from Freddie Mac, acting through a servicer.

We also continue to make additional strategic JV Equity Investments for the development of market-rate multifamily residential and seniors housing properties, through noncontrolling membership interests. We believe such equity investments diversify our investment portfolio while also providing attractive risk-adjusted returns for our Unitholders.

Financing Strategy

We finance our assets with what we believe to be a prudent amount of leverage, the level of which varies from time to time based upon the characteristics of our investment portfolio, availability of financing, cost of financing, and market conditions. This leverage strategy allows us to generate enhanced returns and lowers our net

5

capital investment, allowing us to make additional investments. We currently obtain leverage on our investments and assets through various sources that include:

We may utilize other types of secured or unsecured borrowings in the future, including more complex financing structures and diversification of our leverage sources and counterparties.

We refer to our TEBS, TOB trust, and term TOB trust securitizations and our Secured Notes as our debt financings. The TEBS, TOB trust and term TOB trust securitizations are accounted for as consolidated variable interest entities (“VIEs”) for reporting purposes. These arrangements are structured such that we transfer our investment assets to an entity, such as a trust or special purpose entity, which then issues senior securities and residual interests. The senior securities are sold to third-party investors in exchange for debt proceeds. We retain the residual interests which entitle us to certain rights to the investment assets and to residual cash proceeds. We generally structure our debt financings such that principal, interest, and any trust expenses are payable from the cash flows of the secured investment assets, and we are generally entitled to all residual cash flows for our general use. As the residual interest holder, we may be required to make certain payments or contribute certain assets to the VIEs if certain events occur. Such events include, but are not limited to, a downgrade in the investment rating of the senior securities issued by the VIEs, a ratings downgrade of the liquidity provider for the VIEs, increases in short term interest rates beyond pre-set maximums, an inability to re-market the senior securities or an inability to obtain liquidity support for the senior securities. If such an event occurs in an individual VIE, we may be required to deleverage the VIE by repurchasing some or all of the senior securities. Otherwise, the secured investment asset will be sold and we will be required to fund any shortfall in funds available to pay the principal amount of the senior securities after payment of accrued interest and other trust expenses. If we do not fund the shortfall, default and liquidation provisions will be invoked against us. Each of the TEBS financings are non-recourse to the Partnership such that our shortfall funding for each TEBS financing is limited to the stated amount of our residual interests. The TOB trust and term TOB trust financings are recourse obligations of the Partnership.

The TOB trusts and Secured Notes with Mizuho and the TOB trust with Barclays are subject to ISDA master agreements with each counterparty that contain certain covenants and requirements. The TOB trust financings with Mizuho and Barclays require that the Partnership’s residual interests in each TOB trust maintain a certain value in relation to total assets in each TOB trust. The Mizuho and Barclays ISDA master agreements also require the Partnership’s partners’ capital, as defined, to maintain a certain threshold and that the BUCs remain listed on a national securities exchange. The ISDA master agreement with Barclays also puts limits on the Partnership’s Leverage Ratio (as defined by the Partnership below). In addition, both the Mizuho and Barclays ISDA master agreements specify that default(s) on the Partnership’s other senior debts above a specified dollar amount, in the aggregate, will constitute a default under such agreement. If the Partnership is not in compliance with any of these covenants, a termination event of the financing facilities would be triggered.

We may also be required to post collateral, typically cash, related to the TOB trust financings under the terms of the ISDA master agreements with Mizuho and Barclays. The amount of collateral posting required is dependent on the valuation of the securitized assets and any interest rate swap entered into as a hedge in relation to certain thresholds set by Mizuho and Barclays.

The willingness of leverage providers to extend financing is dependent on various factors such as their underwriting standards, regulatory requirements, available lending capacity, and existing credit exposure to the Partnership. An inability to access debt financing at an acceptable cost may result in adverse effects on our financial condition and results of operations. There can be no assurance that we will be able to finance additional acquisitions of MRBs, GILs and other investments through additional debt financings.

6

We set target constraints for each type of debt financing utilized. Those constraints are dependent upon several factors, including the investment assets being leveraged, the tenor of the leverage program, whether the financing is subject to mark-to-market based collateral calls, and the liquidity and marketability of the financed assets. The Board of Managers of Greystone Manager establishes an overall maximum leverage level (the “Leverage Ratio”) and retains the right to change the Leverage Ratio in the future based on the consideration of factors the Board of Managers considers relevant. In February 2023, the Board of Managers approved an increase in the maximum leverage ratio from 75% to 80%. We calculate our Leverage Ratio as total outstanding debt divided by total assets using cost (adjusted for paydowns) for MRBs, GILs, property loans, taxable MRBs and taxable GILs, and initial cost for deferred financing costs and real estate assets. As of September 30, 2023, our overall Leverage Ratio was approximately 72%.

Hedging Strategy

We actively manage both our fixed and variable rate debt financings and our exposure to changes in market interest rates. When possible, we attempt to obtain fixed-rate debt financing for our fixed-rate investment assets such that our net interest spread is not exposed to changes in market interest rates. Similarly, we attempt to obtain variable-rate debt financing for our variable-rate investment assets such that we are largely hedged against rising interest rates without the need for separate hedging instruments.

We leverage certain fixed-rate investment assets with variable-rate debt financings, such as the TOB trusts, Secured Notes and one TEBS financing. When deemed appropriate, we will enter into derivative based hedging transactions in connection with our risk management activities for these assets to hedge against rising interest rates, which may include interest rate caps, interest rate swaps, total return swaps, swaptions, futures, options or other available hedging instruments. As of September 30, 2023, we held interest rate swaps with notional amounts totaling $314.8 million and one interest rate cap with a notional amount of $73.9 million.

Preferred Units and BUCs Issuances

In addition to leverage, we may obtain additional capital through the issuance of one or more additional series of preferred units, and/or BUCs. We may issue additional series of preferred equity in private placements or public offerings which are registered with the SEC.

We may also obtain capital through the issuance of additional BUCs, Preferred Units or debt securities pursuant to our Registration Statement on Form S-3 (the “Universal Shelf Registration Statement”), which was declared effective by the SEC in December 2022. Under the Universal Shelf Registration Statement we may offer up to $300.0 million of BUCs, Preferred Units or debt securities for sale from time to time. The Universal Shelf Registration Statement will expire in December 2025.

In July 2021, we entered into a Capital on DemandTM Sales Agreement to offer and sell, from time to time at market prices on the date of sale, BUCs up to an aggregate offering price of $30 million via an “at the market offering.” As of September 30, 2023, we have not sold any BUCs under this program. We will continue to assess if and when to issue BUCs under this program going forward.

Reportable Segments

As of September 30, 2023, we had four reportable segments: (1) Affordable Multifamily MRB Investments, (2) Seniors and Skilled Nursing MRB Investments, (3) Market-Rate Joint Venture Investments, and (4) MF Properties. The Partnership separately reports its consolidation and elimination information because it does not allocate certain items to the segments.

Community Investments

Community Reinvestment Act of 1977

The CRA requires the three federal bank supervisory agencies, the Federal Reserve Board (“FRB”), the Office of the Comptroller of the Currency (“OCC”), and the Federal Deposit Insurance Corporation (“FDIC”), to encourage the institutions they regulate to help meet the credit needs of their local communities, including low- to moderate-income neighborhoods. Each agency has promulgated rules for evaluating and rating an institution’s CRA performance which, as the following summary indicates, vary according to an institution’s asset size and business lines. An institution’s CRA performance can also be adversely affected by evidence of discriminatory credit practices regardless of its asset size.

In June 2020, the OCC adopted amendments to its CRA regulations that resulted in the financial institutions for which it is the primary federal regulator (i.e., national banks and federal savings associations) to be subject to different CRA standards than those that apply to the state-chartered banks for which either the FDIC or FRB is the primary federal regulator. Parts of this June 2020 amendment to the OCC’s CRA regulations became effective on October 1, 2020, but the more material provisions would not have taken effect until January 1, 2023 or January 1, 2024. On September 8, 2021, the OCC issued a proposal to rescind its June 2020 final rule and replace it with a rule largely based on its CRA regulations that existed prior to the adoption of its June 2020 amendments. The OCC stated in the preamble to this proposal that it intended to align its CRA rules with the FRB’s and FDIC’s CRA rules, and thereby reinstitute the regulatory uniformity for all insured depository institutions that existed prior to the OCC’s adoption of its June 2020 rule. On December 14, 2021, the OCC adopted a final rule implementing these changes to its CRA regulations, which became effective on January 1, 2022.

CRA Qualified Investments and Community Development Investments

The Partnership has invested and intends to invest in assets which are and will be purchased in order to support underlying community development activities targeted to low- and moderate-income individuals, such as affordable housing, small business lending, and job creating activities in areas of the United States. In this regard, the General Partner expects that a majority of the assets held by the Partnership will be considered eligible for regulatory credit under the CRA. In most cases, “qualified investments” are required to be responsive to the community development needs of a financial institution’s delineated CRA assessment area or a broader statewide or regional area that includes the institution’s assessment area. The OCC’s 2020 amendment to its CRA regulations replaced the term “qualified investments” with “community development investments” which the regulation defined to include lawful investments or legally binding commitments to invest that are reported on the Call Report, Schedule RC–L, that meet the expanded community development “qualifying activities” criteria in the rule.

For this purpose, the amended OCC regulation defines a “qualifying activity,” in part, as a retail loan, a community development loan, a community development investment, or a community development service that helps to meet the credit needs of a bank’s entire community, including low-and moderate-income communities, and that meets the specific additional criteria set forth in the rule. The rule sets forth “qualifying activity” criteria designed to capture activities that currently receive CRA consideration and that are widely recognized by stakeholders as supporting community reinvestment and development. In this respect, community reinvestment and development activities that qualify for positive CRA consideration under the OCC’s former regulation are expected to qualify for positive CRA consideration under the new regulation as well. The “qualifying activity” criteria also capture activities that are consistent with the statutory purpose of the CRA but that generally may not have previously received credit, including certain activities in identified areas of need beyond low- and moderate-income areas (i.e., underserved areas, distressed areas, disaster areas, Indian country and other tribal and native lands). The criteria also include a limited set of activities that benefit a whole community, while maintaining a focus on low- and moderate-income neighborhoods. The final rule requires the OCC to periodically publish a non-exhaustive,

illustrative list of examples of qualifying activities. The final rule also establishes a process for banks to seek agency confirmation that an activity is a qualifying activity.

The amended OCC CRA regulations also revise the process for establishing a national bank or federal savings association’s assessment area for purposes of determining its compliance with the CRA. The final rule changes the current reliance on a financial institution’s physical branch footprint to a framework that utilizes both

8

the traditional branch-based assessment areas and, for banks that gather deposits through the Internet and other non-branch-based channels, broader assessment areas delineated based upon the areas from which they draw more than a specified percentage of assets. Under the final rule, financial institutions that collect above 50% of their total retail domestic deposits from outside of their physical branch footprint must delineate additional assessment areas in those areas where they draw more than 5% of retail domestic deposits. Banks may delineate these additional assessment areas as broadly as statewide.

In certain cases, investments outside an institution’s assessment area may be eligible for CRA credit (for example, certain investments that serve designated disaster areas). For an institution to receive CRA credit with respect to the Partnership’s Series B Preferred Units, the Partnership must hold CRA qualifying investments that relate to the institution’s assessment area. As defined in the CRA, qualified investments are any lawful investments, deposits, membership shares, or grants that have as their primary purpose community development. The term “community development” is defined in the CRA as: (1) affordable housing (including multifamily rental housing) for low- to moderate-income individuals; (2) community services targeted to low- or moderate-income individuals; (3) activities that promote economic development by financing businesses or farms that meet the size eligibility standards of 13 C.F.R. §121.802(a)(2) and (3) or have gross annual revenues of $1 million or less; or (4) activities that revitalize or stabilize low- or moderate-income geographies, designated disaster areas, or distressed or underserved non-metropolitan middle-income geographies designated by the federal banking regulators. In this connection, in the Interagency Questions and Answers Regarding Community Reinvestment published in 2009, the federal bank supervisory agencies stated that nationwide funds are important sources of investments for low- and moderate-income and underserved communities throughout the country and can be an efficient vehicle for institutions in making qualified investments that help meet community development needs. We consider the Partnership to be similar to the funds referenced in this interagency guidance.

Investments are not typically designated as qualifying investments by the OCC, FRB or FDIC, at the time of issuance. Accordingly, the General Partner must evaluate whether each potential investment may be a qualifying investment with respect to a specific Unitholder. The final determinations that Partnership units are qualifying investments are made by the OCC, FRB or FDIC and, where applicable, state bank supervisory agencies during their periodic examinations of financial institutions. There is no assurance that the agencies will concur with the General Partner’s determinations.

In determining whether a particular investment is qualified, the General Partner will assess whether the investment has as its primary purpose community development. The General Partner will consider whether the investment: (i) provides affordable housing for low- to moderate-income individuals; (ii) provides community services targeted to low- to moderate-income individuals; (iii) funds activities that (a) finance businesses or farms that meet the size eligibility standards of the Small Business Administration’s Development Company or Small Business Investment Company programs or have annual revenues of $1 million or less and (b) promote economic development; or (iv) funds activities that revitalize or stabilize low- to moderate-income areas.

For institutions whose primary regulator is the FRB or FDIC, the General Partner may also consider whether an investment revitalizes or stabilizes a designated disaster area or an area designated by those agencies as a distressed or underserved non-metropolitan middle-income area. For institutions whose primary regulator is the OCC, the General Partner may consider whether an investment is consistent with a bona fide government revitalization, stabilization, or recovery plan for a low- or moderate-income census tract, a distressed area, an underserved area, a disaster area, or Indian country or other tribal and native lands. The General Partner will also assess whether the investment supports, enables, or facilitates certain projects or activities that meet the “eligible uses” criteria described in the Housing and Income Recovery Act of 2008. The “eligible uses” include: (i) establishing financing mechanisms for purchase and redevelopment of foreclosed upon homes and residential properties, including such mechanisms as cash flow contingent loans, loan loss reserves, and shared-equity loans for low- to moderate-income homebuyers; (ii) purchasing and rehabilitating homes and residential properties that have been abandoned or foreclosed upon, in order to sell, rent, or redevelop such homes and properties; (iii) establishing land banks for homes that have been foreclosed upon; (iv) demolishing blighted structures; and (v) redeveloping demolished or vacant properties.

An activity may be deemed to promote economic development if it supports permanent job creation, retention, and/or improvement for persons who are currently low- to moderate-income, or supports permanent job

9

creation, retention, and/or improvement in low- to moderate-income areas targeted for redevelopment by federal, state, local, or tribal governments. Activities that revitalize or stabilize a low- to moderate-income geography are activities that help attract and retain businesses and residents. The General Partner maintains documentation, readily available to a financial institution or a CRA examiner, supporting its determination that a Partnership asset is a qualifying investment for CRA purposes.

There may be a time lag between the issuance of Series B Preferred Units to an investor and the Partnership’s acquisition of a significant volume of investments in a particular geographic area. The length of time will depend upon the depth of the market for CRA qualified investments in the relevant areas. In some cases, the General Partner expects that CRA qualified investments will be immediately available. In others, it may take weeks or months to acquire a significant volume of CRA qualified investments in a particular area. The General Partner believes that investments in the Series B Preferred Units during these time periods will be considered CRA qualified investments, provided the purpose of the Partnership includes serving the investing institution’s assessment area(s) and the Partnership is likely to achieve a significant volume of investments in the region after a reasonable period of time. As the Partnership continues to operate, it may dispose of assets that were acquired for CRA qualifying purposes, in which case the General Partner will normally attempt to acquire a replacement asset that would be a qualifying investment.

So that the Series B Preferred Units of the Partnership may be considered a qualified investment, the General Partner will not, on behalf of the Partnership, invest in any asset that would result in the percentage of the assets held by the Partnership which we believe are eligible for regulatory credit under the CRA (the “CRA Assets”) to fall below a majority of the Partnership’s total assets. The ratio is calculated as the Partnership’s initial investment in CRA Assets divided by the initial investment of the Partnership’s investments held as of the last day of the quarter. In addition, each investor’s returns will be based on the investment performance of the Partnership’s blended overall portfolio of investments, not just on the performance of the assets in the Designated Target Region(s) selected by that investor.

10

The following table sets forth the assets of the Partnership the General Partner believes are eligible for regulatory credit under the CRA and are available for allocation according to the CRA Credit Allocation Methodology as of November 7, 2023:

11

It is the General Partner’s belief and expectation that a financial institution subject to CRA may receive investment credit for its investments in the Series B Preferred Units. In this regard, federal CRA regulations, and their counterparts in many states with their own CRA requirements, require financial institutions subject to these provisions to focus upon community development in making investments. The General Partner believes that federal and state banking regulators (in those states with their own CRA requirements) will recognize an investment in the Series B Preferred Units as a qualified community development investment. However, there is no guarantee that an investor will receive CRA credit for its investment in the Series B Preferred Units.

As described above, a principal objective of the Partnership’s investment activities is to provide investors a competitive return on investment from a high credit quality fixed-income portfolio that supports underlying community development activities in distinct parts of the United States. However, some of the investors in the Series B Preferred Units may not be subject to CRA requirements, but rather may be investors seeking a fixed-income investment with high credit quality to assist in their asset allocation program. Investors also may be seeking to make investments in underserved communities or fulfilling other socially responsible or mission-related investment objectives. Those investors that are not subject to CRA requirements will not receive CRA credit for their investments.

The discussion of CRA credit contained in this prospectus is general and may be affected by future regulations and rulings. Potential investors contemplating an investment in Series B Preferred Units are urged to consult with counsel regarding the qualification of such purchase for CRA credit.

CRA Credit Allocation Methodology

If a potential investor decides to invest in the Series B Preferred Units, the investor’s agreement to invest in the units will be evidenced by an exchange, subscription, redemption, or similar agreement and other related documents as described below in “Plan of Distribution.”

As part of a potential investor’s definitive investment agreement, each investor must designate a Designated Target Region as the preferred geographic focus for its investment. Investors may designate more than one Designated Target Region. If, at the time a potential investor submits an executed investment agreement, the Partnership holds CRA Assets in the Designated Target Region(s) set forth in the investor’s investment agreement, the investor may specify the amount of the investor’s investment to be allocated to one or more such CRA Assets (the “Specified CRA Assets”). The total amount of the allocations requested by the potential investor cannot be greater than the aggregate value of the Series B Preferred Units issued to the investor, as set forth in the investor’s investment agreement. Allocation requests to Specified CRA Assets will be honored by the General Partner on a first come, first serve basis, prioritized based on the date the General Partner receives a potential investor’s completed and executed investment agreement and related documents. If the General Partner receives completed and executed investment documents from two or more potential investors on the same date, and the investment agreements for the investors request an allocation to one or more of the same Specified CRA Assets, and the total amount of the requested allocations exceeds the aggregate amount available to be allocated for those Specified CRA

12

Assets, then the General Partner will allocate such investors’ investment amounts among the Specified CRA Assets, pro rata, based on the relative amount of the allocations requested by the investors for the Specified CRA Assets.

If a potential investor does not request that its investment amount be allocated to any Specified CRA Assets, then the General Partner will allocate, in its discretion, such investor’s investment amount among CRA Assets located within the Designated Target Region set forth in the investor’s investment agreement.

Finally, if a CRA Asset held by the Partnership at the time the General Partner receives completed and executed investment documents from a potential investor is no longer held by the Partnership upon the date of the closing of the investor’s investment, the General Partner will notify the potential investor and (i) if such investor requested allocations to Specified CRA Assets in its investment agreement, the General Partner will request the investor to specify in writing, no later than three business days after the receipt of the General Partner’s notice, other Specified CRA Assets then held by the Partnership to which the investor’s investment amount should be allocated, and (ii) if such investor did not originally request an allocation to any Specified CRA Assets in its investment agreement or, after receiving the notification from the General Partner described in this paragraph, declines to specify other Specified CRA Assets to which its investment amount should be allocated, then the General Partner will allocate, in its discretion, such investor’s investment amount among CRA Assets located within the Designated Target Region set forth in the investor’s investment agreement. For purposes of the reallocations described in this paragraph, the General Partner will adhere to the pro rata allocation methodology described above to the extent pro ration of requested allocations is applicable.

Investment Types

Mortgage Revenue Bonds (“MRBs”)

We invest in MRBs that are issued by state and local governments, their agencies, and authorities to finance the construction or acquisition and rehabilitation of income-producing multifamily rental properties. An MRB does not constitute an obligation of any state or local government, agency or authority and no state or local government, agency or authority is liable on them, nor is the taxing power of any state or local government pledged to the payment of principal or interest on an MRB. An MRB is a non-recourse obligation of the property owner. Each MRB is collateralized by a mortgage on all real and personal property of the secured property, which it may share with a corresponding taxable MRB owned by the Partnership. Typically, the sole source of the funds to pay principal and interest on an MRB is the net cash flow or the sale or refinancing proceeds from the secured property. We may commit to provide funding for MRBs on a draw-down basis during construction and/or rehabilitation of the secured property, and we may require recourse to the borrower during the construction or rehabilitation period in certain instances.

We expect and believe that the interest received on our MRBs is excludable from gross income for federal income tax purposes. We primarily invest in MRBs that are senior obligations of the secured properties, though we may also invest in subordinate MRBs. Our MRBs predominantly bear interest at fixed interest rates and require regular principal and interest payments on either a monthly or semi-annual basis. The majority of our MRBs have initial contractual terms of 15 years or more. MRBs may have optional call dates that may be exercised by the borrower or us that are earlier than the contractual maturity. Such optional calls may be at either par or a premium to par.

As of September 30, 2023, we reported 84 MRBs on our consolidated balance sheet with an aggregate outstanding principal amount of approximately $867.0 million. The MRBs are secured by 70 multifamily residential properties containing a total of 11,325 rental units located in 12 states in the United States. Two MRBs are secured by a mortgage on the ground, facilities, and equipment of seniors housing properties. One MRB is secured by a mortgage on the ground, facilities, and equipment of a commercial ancillary health care facility in Tennessee. Our MRBs are either owned directly by us or are held in trusts created in connection with debt financing transactions that are consolidated VIEs.

The four types of MRBs which we may acquire as investments are as follows:

13

Each of these structures permit the issuance of MRBs under the IRC to finance the construction or acquisition and rehabilitation of affordable rental housing or other not-for-profit commercial property. Under applicable Treasury Regulations, any affordable multifamily residential project financed with tax-exempt MRBs (other than essential function bonds as described in the third bullet above) must set aside a percentage of its total rental units for occupancy by tenants whose incomes do not exceed stated percentages of the median income in the local area. Those rental units of the multifamily residential project not subject to tenant income restrictions may be rented at market rates (unless there are restrictions otherwise imposed by the bond issuer or a governmental entity). With respect to private activity bonds issued under Section 142(d) of the IRC, the owner of the multifamily residential project may elect, at the time the MRBs are issued, whether to set aside a minimum of 20% of the units for tenants making less than 50% of area median income (as adjusted for household size) or 40% of the units for tenants making less than 60% of the area median income (as adjusted for household size). State and local housing authorities may require additional tenant income or rent restrictions that are more restrictive than those required by Treasury Regulations. There are no Treasury Regulations related to MRBs that are secured by a commercial property owned by a non-profit borrower.

The borrowers associated with our MRBs are either syndicated partnerships formed to receive allocations of LIHTCs or not-for-profit entities. We do not directly or indirectly invest in LIHTCs but invest in MRBs that are issued in association with federal LIHTC allocations because such MRBs bear interest that we expect and believe is exempt from federal income taxes. LIHTC-eligible projects are attractive to developers of affordable housing because it helps them raise equity and debt financing. Under the LIHTC program, developers that receive an allocation of private activity bonds will also receive an allocation of federal LIHTCs as a method to encourage the development of affordable multifamily housing. To be eligible for federal LIHTCs, a property must either be newly constructed or substantially rehabilitated, and therefore, may be less likely to become functionally obsolete in the near term as compared to an older property. There are various requirements to be eligible for federal LIHTCs, including rent and tenant income restrictions, which vary by property. Our borrowers that are either non-profit entities or owned by non-profit entities typically have missions to provide affordable multifamily rental units to underserved populations in their market areas. The affordable housing properties securing 501(c)(3) bonds also must comply with the IRS safe harbors for tenant incomes and rents.

We may also invest in taxable MRBs secured by the same properties as our MRBs. Interest earned on our taxable MRBs is taxable for federal income tax purposes. Our taxable MRBs may share senior mortgage interest in the property with the MRBs or may be subordinate to the MRBs.

Governmental Issuer Loans (“GILs”)

We invest in GILs that are issued by state or local governmental authorities to finance the construction of affordable multifamily properties. A GIL does not constitute an obligation of any government, agency or authority and no government, agency or authority is liable for them, nor is the taxing power of any government pledged to the payment of principal or interest on the GIL. Each GIL is secured by a mortgage on all real and personal property of the to-be-constructed affordable multifamily property. The GILs may share first mortgage lien positions with property loans and/or taxable GILs also owned by us. Sources of the funds to pay principal and interest on a GIL consist of the net cash flow of the secured property, proceeds from the sale or refinancing of the secured property, and limited-to-full payment guaranties provided by affiliates of the borrower. We typically commit to fund our GIL investment commitments on a draw-down basis during construction.

We expect and believe the interest earned on our GILs is excludable from gross income for federal income tax purposes. The GILs are senior obligations of the secured properties and bear interest at variable interest rates. The GILs have initial terms of two to four years, though the borrower typically may prepay all amounts due at any time without penalty. At the closing of each GIL, Freddie Mac, through a servicer, has forward committed to purchase the GIL at maturity at par if and when the property has reached stabilization and other conditions are met. Upon stabilization, the servicer will purchase our GIL at par and then immediately sell the GIL to Freddie Mac pursuant to a financing commitment between the servicer and Freddie Mac. As of September 30, 2023, the servicer for nine of our GILs is an affiliate of Greystone.

As of September 30, 2023, we reported 10 GILs on our consolidated balance sheet with an aggregate outstanding principal amount of approximately $255.9 million. In addition, we had remaining funding commitments of $56.6 million as of September 30, 2023. Such GILs are secured by 10 affordable multifamily properties containing a total of 1,927 rental units located in 5 states in the United States. All of our GILs are held in trusts created in connection with debt financing transactions that are consolidated VIEs.

Our GILs have been issued under Section 142(d) of the Internal Revenue Code (“IRC”) and are subject to the same set aside and tenant income restrictions noted in the “Mortgage Revenue Bonds” description above. The borrowers associated with our GILs are syndicated partnerships formed to receive allocations of LIHTCs.

JV Equity Investments

We invest in non-controlling membership interests in unconsolidated entities for the construction of market-rate multifamily real estate properties. Our JV Equity Investments are passive in nature. Operational oversight of each property is controlled by our joint venture partner according to the entity’s operating agreement. All properties are managed by a property management company affiliated with our joint venture partner. Decisions on when to sell an individual property are made by our joint venture partner based on its view of the local market conditions and current leasing trends.

We account for our JV Equity Investments using the equity method and recognize a preferred return on our contributed equity during the hold period. The accrued preferred return for our JV Equity Investments held through our wholly owned subsidiary, ATAX Vantage Holdings, LLC (the “Vantage JV Equity Investments”), is guaranteed by an unrelated third party through the fifth anniversary of construction commencement up to a certain dollar amount on an individual project basis.

Our ownership of the membership interests entitles us to shares of certain cash flows generated by the JV Equity Investments from operations and upon the occurrence of certain capital transactions, such as a refinancing or sale. Upon the sale of a property, net proceeds will be distributed according to the entity operating agreement. Sales proceeds distributed to us that represent previously unrecognized preferred return and gain on sale are recognized as income upon receipt. Historically, the majority of our income from our JV Equity Investments has been recognized at the time of sale. As a result, we may experience significant income recognition in those quarters when a property is sold and our equity investment is redeemed.

As of September 30, 2023, we owned membership interests in 11 JV Equity Investments located in four states in the United States. Of the 11 JV Equity Investments, seven are located in Texas. In addition, one JV Equity Investment in San Marcos, Texas is reported as a consolidated VIE.

MF Properties

The Partnership has and may acquire controlling interests in multifamily, student or senior citizen residential properties. We operate the MF Properties in order to position ourselves for a future investment in MRBs issued to finance the acquisition and/or rehabilitation of the properties by new owners or until the opportunity arises to sell the MF Properties at what we believe is their optimal fair value.

As of September 30, 2023, we owned one MF Property, the Suites on Paseo, containing a total of 384 rental units located in California.

Property Loans

We also invest in property loans to finance the construction, finance capital improvements, or otherwise support property operations of multifamily residential properties. Multifamily residential properties financed with property loans may or may not be properties securing our MRB and GIL investments. Such property loans may be secured by property, other collateral, or may be unsecured.

General Investment Matters

Our investments are categorized as either Mortgage Investments, Tax Exempt Investments or Other Investments as defined in our Partnership Agreement. Mortgage Investments, as defined, consist of MRBs, taxable MRBs, GILs, taxable GILs and property loans to borrowers associated with our MRBs and GILs. Tax Exempt Investments, as defined, are securities, other than Mortgage Investments, for which the related interest income is exempt from federal income taxation and must be rated in one of the four highest rating categories by a nationally recognized statistical rating organization. Other Investments, as defined, are generally all other investments that are not Mortgage Investments or Tax Exempt Investments. We may acquire additional Tax Exempt Investments and Other Investments provided that the acquisition may not cause the aggregate book value of all Tax Exempt Investments plus Other Investments to exceed 25% of our total assets at the time of acquisition. We currently own no Tax Exempt Investments as of September 30, 2023. Our Other Investments primarily consist of MF Properties, other real estate assets, JV Equity Investments and certain property loans as of September 30, 2023.

We rely on an exemption from registration under the Investment Company Act of 1940, which has certain restrictions on the types and amounts of securities owned by the Partnership.

Cash Distributions

We currently make quarterly cash distributions to our BUC holders. The Partnership Agreement allows the General Partner to elect to make cash distributions on a more or less frequent basis, provided that distributions are made at least semi-annually. Regardless of the distribution period selected, cash distributions to BUC holders must be made within 60 days of the end of each such period. The amount of any cash distribution is determined by the General Partner and depends on the amount of interest received on our MRBs, GILs and other investments, our financing costs which are affected by the interest rates we pay on our debt financing, the amount of cash held in our reserves, and other factors. Most recently we declared our regular third quarter 2023 distribution of $0.37 per outstanding BUC and a supplemental distribution payable in the form of additional BUCs equal to $0.07 per BUC. The cash distribution and supplemental BUCs distribution were paid on October 31, 2023 to BUC holders of record as of the close of trading on September 29, 2023.

The holders of our Series A Preferred Units are entitled to receive, when, as, and if declared by the General Partner out of funds legally available for the payment of distributions, non-cumulative cash distributions at the rate of 3.00% per annum of the $10.00 per unit purchase price of the Series A Preferred Units, payable quarterly.
