	Basis of Presentation
	General
	America First Multifamily Investors, L.P. (the “Partnership”) was formed on April 2, 1998, under the Delaware Revised Uniform Limited Partnership Act for the primary purpose of acquiring, holding, selling and otherwise dealing with a portfolio of mortgage revenue bonds which have been issued to provide construction and/or permanent financing of multifamily residential properties.  The Partnership expects and believes the interest earned on these mortgage revenue bonds is excludable from gross income for federal income tax purposes.  As a result, most of the income earned by the Partnership is exempt from federal income taxes.  The Partnership may also invest in other types of securities that may or may not be secured by real estate and may make taxable property loans secured by multifamily properties which are financed by mortgage revenue bonds held by the Partnership.  The Partnership generally does not seek to acquire direct interests in real property as long term or permanent investments.  The Partnership may, however, acquire real estate securing its mortgage revenue bonds or taxable mortgage loans through foreclosure in the event of a default.  In addition, the Partnership may acquire interests in multifamily apartment properties (“MF Properties”) in order to position itself for future investments in mortgage revenue bonds issued to finance these properties. The Partnership expects to sell its interest in these MF Properties in connection with the future syndication of low income housing tax credits under Section 42 of the Internal Revenue Code (“LIHTCs”) or to a tax-exempt organization and to acquire mortgage revenue bonds on these properties to provide debt financing to the new owners.
	Our general partner is America First Capital Associates Limited Partnership Two (“AFCA 2” or “General Partner”).  The general partner of AFCA2 is The Burlington Capital Group LLC (“Burlington”). The Partnership has issued Beneficial Unit Certificates (“BUCs”) representing assigned limited partner interests to investors (“unitholders”).  The Partnership will terminate on December 31, 2050, unless terminated earlier under provisions of its Agreement of Limited Partnership.
	The “Company” refers to the consolidated financial statements reported in this Form 10-Q which include the assets, liabilities, and results of operations of the Partnership, its Consolidated Subsidiaries (defined below) and two entities in which the Partnership does not hold an ownership interest but which own multifamily apartment properties financed with mortgage revenue bonds held by the Partnership and which are treated as variable interest entities (“VIEs”) of which the Partnership has been determined to be the primary beneficiary (the “Consolidated VIEs”). On June 30, 2014, the Consolidated Subsidiaries of the Partnership consist of:
	•	ATAX TEBS I, LLC, a special purpose entity owned and controlled by the Partnership, created to hold mortgage revenue bonds in order to facilitate the Tax Exempt Bond Securitization (“TEBS”) Financing with Freddie Mac (Note 10).
	•	Nine multifamily apartments (“MF Properties”) which are either wholly or majority owned by subsidiaries of the Partnership.
	Stand alone financial information of the Partnership reported in this Form 10-Q includes only the assets, liabilities, and results of operations of the Partnership and its Consolidated Subsidiaries (hereafter the “Partnership”) without the Consolidated VIEs.  In the Company’s consolidated financial statements, all transactions and accounts between the Partnership, the Consolidated Subsidiaries and the Consolidated VIEs have been eliminated in consolidation.  The Partnership does not believe that the consolidation of VIEs for reporting under accounting principles generally accepted in the United States of America (“GAAP”) affects the Partnership’s status as a partnership for federal income tax purposes or the status of unitholders as partners of the Partnership, the treatment of the mortgage revenue bonds on the properties owned by Consolidated VIEs as debt, the nature of the interest payments, which it believes to be tax-exempt, received on the mortgage revenue bonds secured by the properties owned by Consolidated VIEs or the manner in which the Partnership’s income is reported to unitholders on IRS Form K-1.
	The unallocated deficit of the Consolidated VIEs is primarily comprised of the accumulated historical net losses of the Consolidated VIEs since the applicable consolidation date. The unallocated deficit of the VIEs and the VIEs’ net losses subsequent to that date are not allocated to the General Partner and unitholders as such activity is not contemplated by, or addressed in, the Agreement of Limited Partnership.
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.  The accompanying interim unaudited condensed consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted according to such rules and regulations, although management believes that the disclosures are adequate to make the information presented not misleading. The condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013. These condensed consolidated financial statements and notes have been prepared consistently with the 2013 Form 10-K. In the opinion of management, all adjustments (consisting of normal and recurring accruals) necessary to present fairly the financial position as of June 30, 2014, and the results of operations for the interim periods presented have been made. The results of operations for the interim period are not necessarily indicative of the results to be expected for the full year.
	Subsequent to the issuance of the Company’s financial statements on Form 10-K for the period ended December 31, 2013, certain amounts included in the Consolidated Balance Sheet have been restated to correct an error related to the presentation of interest receivable on taxable loans.  Such correction recorded the loan loss reserve related to interest receivable against the interest receivable line of the consolidated balance sheet rather than against the other assets line, which includes the principle amount of taxable loans.   This correction resulted in a decrease in interest receivable and an increase in other assets of approximately $6.2 million.  This correction did not have an impact on total assets as reported in the Consolidated Balance Sheets and did not have an impact on the Consolidated Statements of Operations for all periods presented.

	Partnership Income, Expenses and Cash Distributions
	The Agreement of Limited Partnership of the Partnership contains provisions for the distribution of Net Interest Income, Net Residual Proceeds and Liquidation Proceeds, for the allocation of income or loss from operations and for the allocation of income and loss arising from a repayment, sale, or liquidation of investments.  Income and losses will be allocated to each unitholder on a periodic basis, as determined by the General Partner, based on the number of BUCs held by each unitholder as of the last day of the period for which such allocation is to be made. Distributions of Net Interest Income and Net Residual Proceeds will be made to each unitholder of record on the last day of each distribution period based on the number of BUCs held by each unitholder as of such date. For purposes of the Agreement of Limited Partnership, cash distributions, if any, received by the Partnership from its indirect interest in MF Properties (Note 7) will be included in the Partnership’s Interest Income and cash distributions received by the Partnership from the sale of such properties will be included in the Partnership’s Residual Proceeds.
	Cash distributions are currently made on a quarterly basis but may be made on a monthly or semiannual basis at the election of AFCA 2.  On each distribution date, Net Interest Income is distributed 99% to the unitholders and 1% to AFCA 2 and Net Residual Proceeds are distributed 100% to unitholders except that Net Interest Income and Net Residual Proceeds representing contingent interest in an amount equal to 0.9% per annum of the principal amount of the mortgage revenue bonds on a cumulative basis (defined as Net Interest Income (Tier 2) and Net Residual Proceeds (Tier 2), respectively) are distributed 75% to the unitholders and 25% to AFCA 2.

Variable Interest Entities [Abstract]	'
Variable interest entities [Text Block]	'
	Variable Interest Entities
	The Partnership invests in mortgage revenue bonds which have been issued to provide construction and/or permanent financing of multifamily residential apartments.  The Partnership owns 100% of these mortgage revenue bonds and each bond is secured by a first mortgage on the property.  In certain cases, the Partnership has also made taxable property loans to the property owners which are secured by second mortgages on these properties.  Although each multifamily property financed with mortgage revenue bonds held by the Partnership is owned by a separate entity in which the Partnership has no equity ownership interest, the debt financing provided by the Partnership creates a variable interest in these ownership entities that may require the Partnership to report the assets, liabilities, and results of operations of these entities on a consolidated basis under GAAP.
	At June 30, 2014 and December 31, 2013, the Partnership determined that four of the entities financed by mortgage revenue bonds owned by the Partnership were held by VIEs.  These VIEs were Ashley Square, Bent Tree, Cross Creek, and Fairmont Oaks. The Partnership then determined that it is the primary beneficiary of two of these VIEs; Bent Tree and Fairmont Oaks and has continued to consolidate these entities. As of June 30, 2013, a fifth entity, Lake Forest, which is also financed by a mortgage revenue bond owned by the Partnership, was held by a VIE. Effective December 1, 2013, the ownership of Lake Forest became a not-for-profit entity and Lake Forest ceased to be reported as a Consolidated VIE.
	The Partnership does not hold an equity interest in these VIEs and, therefore, the assets of the VIEs cannot be used to settle the general commitments of the Partnership and the Partnership is not responsible for the commitments and liabilities of the VIEs.  The primary risks to the Partnership associated with these VIEs relate to the entities’ ability to meet debt service obligations to the Partnership and the valuation of the underlying multifamily apartment property which serves as bond collateral.
	The following is a discussion of the significant judgments and assumptions made by the Partnership in determining the primary beneficiary of the VIE and, therefore, whether the Partnership must consolidate the VIE.
	Consolidated VIEs
	In determining the primary beneficiary of these VIEs, the Partnership considers the activities of the VIE which most significantly impact the VIEs’ economic performance, who has the power to control such activities, the risks which the entities were designed to create, the variability associated with those risks and the interests which absorb such variability.  The Partnership also considers the related party relationship of the entities involved in the VIEs.  At June 30, 2014 and December 31, 2013, the Partnership determined it is the primary beneficiary of the Bent Tree and Fairmont Oaks VIEs. The capital structure of Bent Tree and Fairmont Oaks VIEs consists of senior debt, subordinated debt, and equity capital. The senior debt is in the form of a mortgage revenue bond and accounts for the majority of the VIEs’ total capital. As the bondholder, the Partnership is entitled to principal and interest payments and has certain protective rights as established by the bond documents. The equity ownership of the consolidated VIEs is ultimately held by corporations which are owned by four individuals, two of which are related parties.  Additionally, each of these properties is managed by an affiliate of the Partnership, America First Properties Management Company, LLC (“Properties Management”) which is an affiliate of Burlington Capital Group, LLC (“Burlington”).
	Non-Consolidated VIEs
	The Company did not consolidate two VIE entities, Ashley Square and Cross Creek as of June 30, 2014 based on its determination of the primary beneficiary of these two VIE entities. As discussed below, while the capital structures of these VIEs resulted in the Partnership holding a majority of the variable interests in these VIEs, the Partnership determined it does not have the power to direct the activities of these VIEs that most significantly impact the VIEs’ economic performance and, as a result, is not the primary beneficiary of these VIEs.
	Ashley Square –  Ashley Square Housing Cooperative acquired the ownership of the Ashley Square Apartments in December 2008 from Ashley Square LLC through a warranty deed of transfer and an assumption of debt.  This transfer of ownership constituted a reconsideration event as outlined in the consolidation guidance which triggered a re-evaluation of the holders of variable interests to determine the primary beneficiary of the VIE.  The capital structure of the VIE consists of senior debt, subordinated loans and equity capital.  The senior debt is in the form of mortgage revenue bonds that are 100% owned by the Partnership and account for the majority of the VIE’s total capital.  As the bondholder, the Partnership is entitled to principal and interest payments and has certain protective rights as established by the bond documents.  The VIE is organized as a housing cooperative and the 99% equity owner of this VIE is The Foundation for Affordable Housing (“FAH”), an unaffiliated Nebraska not-for-profit organization.  Additionally, this property is managed by Properties Management.
	Cross Creek –  Cross Creek Apartments Holdings LLC is the owner of the Cross Creek Apartments.  On January 1, 2010, Cross Creek Apartment Holdings LLC entered into a new operating agreement and admitted three new members.  These new members committed approximately $2.2 million of capital payable in three installments including $563,000 on January 1, 2010.  The new operating agreement and admission of new owner members constituted a reconsideration event as outlined in the consolidation guidance which triggered a re-evaluation of the holders of variable interests to determine the primary beneficiary of the VIE.  The capital structure of the VIE consists of senior debt, subordinated loans, and equity capital at risk.  The senior debt is in the form of mortgage revenue bonds that are 100% owned by the Partnership and account for the majority of the VIE’s total capital.  As the bondholder, the Partnership is entitled to principal and interest payments and has certain protective rights as established by the bond documents.  The three newly admitted members of this VIE are each unaffiliated with the Partnership and have contributed significant equity capital to the VIE.  These members collectively control a 99% interest in the VIE.  The other 1% member of this VIE is FAH, which is also unaffiliated with the Partnership.  Additionally, this property is managed by Properties Management.
	The following table presents information regarding the carrying value and classification of the assets held by the Partnership as of June 30, 2014 which constitute a variable interest in Ashley Square and Cross Creek.
		Balance Sheet Classification		Carrying Value				Maximum Exposure to Loss
	Ashley Square Apartments
	Mortgage Revenue Bond	Bond Investment		$	5,496,609			$	5,188,000
	Taxable Property Loan	Other Asset		1,482,000				7,292,126
				$	6,978,609			$	12,480,126
	Cross Creek Apartments
	Mortgage Revenue Bond	Bond Investment		$	8,133,565			$	6,059,256
	Taxable Property Loans	Other Asset		3,515,615				3,515,615
				$	11,649,180			$	9,574,871
	The mortgage revenue bonds are classified on the balance sheet as available for sale investments and are carried at fair value while taxable property loans are presented on the balance sheet as Other assets and are carried at the unpaid principal and interest less any loan loss reserves.  See Note 4 for additional information regarding the mortgage revenue bonds and Note 8 for additional information regarding the taxable property loans.  The maximum exposure to loss for the mortgage revenue bonds is equal to the unpaid principal balance as of June 30, 2014.  The difference between the mortgage revenue bond’s carrying value and the maximum exposure to loss is a function of the fair value of the bond.  The difference between the taxable property loan’s carrying value and the maximum exposure is the value of loan loss reserves that have been previously recorded against the outstanding taxable property loan balances.
	The following tables present the effects of the consolidation of the Consolidated VIEs on the Company’s Condensed Consolidated Balance Sheets and Condensed Consolidated Statements of Operations.

In June 2014, the Partnership committed to the purchase of an approximate $40.3 million par value mortgage revenue bond secured by the Live 929 Apartments, with a 5.78% annual stated interest rate. The project is a 572-bed existing student housing project on the campus of The Johns Hopkins University School of Medicine in Baltimore, Maryland. This investment will close upon the execution of a $35.0 million tender option bond (“TOB”) Trust under the existing TOB structure (Note 10). At June 30, 2014 the $35.0 million obligation is reported on the balance sheet as Due upon settlement of Live 929 Apartments. This amount will be converted into a TOB financing upon settlement. The remaining cash to close the commitment, approximately $5.3 million, will be paid when the TOB financing is executed and is currently reported in accounts payable and accrued expenses on the balance sheet.
In April 2014, the mortgage revenue bond secured by Autumn Pines was sold for the outstanding principal and accrued base interest. The Company received approximately $13.1 million for the Autumn Pines mortgage revenue bond and recognized a gain of approximately $873,000 after payment of all TOB related financing fees. This gain is Tier 2 income with approximately $650,000 allocated to the unitholders. This mortgage revenue bond had been acquired at a discount on June 1, 2011. The Company’s $9.8 million TOB financing facility which was the securitization of this mortgage revenue bond was collapsed and paid off in full in connection with this sale.
In February 2014, the Partnership acquired at par the senior $7.0 million par value and a subordinate $2.3 million par value mortgage revenue bond secured by Harden Ranch, a 100 unit multifamily apartment complex in Salinas, California. The senior mortgage revenue bond carries an annual interest rate of 5.75% and matures on March 1, 2030. The subordinate mortgage revenue bond carries an annual interest rate of 5.50% for the first year and 8.0% for the second year and matures on March 1, 2016.
In February 2014, the Company acquired at par the senior $23.0 million par value mortgage revenue bond secured by Decatur-Angle Apartments, a 302 unit multifamily apartment complex under construction in Fort Worth, Texas. The mortgage revenue bond carries an annual interest rate of 5.75% and matures on January 1, 2054.
In February 2014, the mortgage revenue bond secured by Lost Creek was redeemed for an amount greater than the outstanding principal and accrued base interest. This $18.5 million par value mortgage revenue bond had been acquired for approximately $15.9 million in May 2010. The Company received approximately $18.7 million for the Lost Creek mortgage revenue bond resulting in an approximate $2.8 million realized gain. This gain was Tier 2 income with 25% allocated to the General Partner.
In December 2013, the Partnership acquired seven mortgage revenue bonds. They are as follows:
•	The Partnership purchased an approximate $5.2 million par value Series A mortgage revenue bond with a stated interest rate of 6.25% per annum secured by Copper Gate Apartments, a 128 unit multifamily complex in Lafayette, Indiana, maturing on December 1, 2029.
•	The Partnership purchased an approximate $6.1 million par value senior and an approximate $2.0 million par value subordinate mortgage revenue bonds with stated interest rates of 5.75% and 5.5% per annum, respectively. These mortgage revenue bonds are secured by Tyler Park Townhomes, an 88 unit multifamily complex in Greenfield, California. The senior mortgage revenue bond matures on January 1, 2030 and the subordinate mortgage revenue bond matures on January 1, 2016.
•	The Partnership purchased an approximate $4.0 million par value senior and an approximate $1.4 million par value subordinate mortgage revenue bonds with stated interest rates of 5.75% and 5.5% per annum, respectively. These mortgage revenue bonds are secured by Westside Village, an 81 unit multifamily complex in Shafter, California. The senior mortgage revenue bond matures on January 1, 2030 and the subordinate mortgage revenue bond matures on January 1, 2016.
•	The Partnership purchased an approximate $20.2 million par value Series A mortgage revenue bond with a stated interest rate of 6.25% per annum secured by The Palms at Premier Park Apartments, a 240 unit multifamily complex in Columbia, South Carolina. This mortgage revenue bond matures on January 1, 2050.
•	The Partnership purchased an approximate $35.8 million par value Series A mortgage revenue bond with a stated interest rate of 6.25% per annum secured by The Suites on Paseo, a 384 bed student housing project in San Diego, California. This mortgage revenue bond matures on December 1, 2048.
Effective December 1, 2013, the ownership of Lake Forest became a not-for-profit entity, a reconsideration event, and Lake Forest ceased to be reported as a Consolidated VIE. As such, the Partnership is reporting the estimated fair value of the Lake Forest mortgage revenue bond as an investment asset for the first time in 2013.
In August 2013, the Partnership acquired a mortgage revenue bond secured by the Vantage at Harlingen Apartments, a 288 unit multifamily apartment complex located in Harlingen, Texas which is under construction. The Series C bond was purchased for approximately $6.7 million par value, carries a base interest rate of 9.0% per annum, and matures on August 1, 2053. The Partnership also acquired a $1.3 million subordinate taxable bond which is recorded as an Other Asset. The Vantage at Harlingen Apartments has a construction loan with an unrelated bank and the Partnership’s mortgage revenue bonds are second lien borrowings to that construction loan.
Under the terms of a Forward Delivery Bond Purchase Agreement (“Bond Purchase Commitment”), the Partnership has agreed to purchase a new mortgage revenue bond between $18,000,000 and $24,692,000 (“Harlingen Series B Bond”) secured by the Vantage at Harlingen apartments which will be delivered by the mortgage revenue bond issuer once the property meets specific obligations and occupancy rates. The final amount of the Series B Bond will depend on the appraisal of the stabilized property. The Harlingen Series B Bond will have a stated annual interest rate of 6.0% per annum and bond proceeds must be used to pay off the construction loan to the bank and all or a portion of the $6.7 million subordinate Series C mortgage revenue bond. The Partnership accounts for the Bond Purchase Commitment as an available-for-sale security and, as such, records the change in the estimated fair value of the Bond Purchase Commitment as an asset or liability with changes in such valuation recorded in other comprehensive income.  As of June 30, 2014, the Partnership estimated the value of this Bond Purchase Commitment and recorded in other assets an asset of approximately $135,000.
In July 2013, the limited partner property owner contributed an approximate additional $800,000 of capital into the Greens Property which allowed the Company to recognize a sale of the discontinued operations (Note 9). As such, the Partnership reported the approximate $10.2 million and $9.1 million fair value of the mortgage revenue bonds related to the Greens Property as assets as of June 30, 2014 and December 31, 2013, respectively.
In June 2013, the Partnership redeemed its interest in the Iona Lakes mortgage revenue bond for approximately $21.9 million. This redemption resulted in the realization of approximately $6.5 million in contingent interest income and approximately $4.6 million realized loss on a taxable property loan. The trust indenture for this bond had a waterfall feature which stipulated that all unpaid contingent interest must be paid prior to making payment on any taxable loan between the owner of the bond and the property.
The Partnership, as sole bondholder, previously directed the bond trustee to file a foreclosure action on the Woodland Park mortgage revenue bond. On February 28, 2013, the court granted Summary Judgment in the bond trustee’s favor confirming that the mortgage revenue bond is senior to mechanic’s liens filed on the property. Woodland Park became an MF Property upon title conveyance which occurred on May 29, 2013 (Note 7). The Partnership requested the mortgage revenue bond issuer to remove the Land Use Restriction Agreement (“LURA”) on the property and the units have been converted to 100% market-rate rents. The Partnership may convert the property back to a rent restricted property, seek to place new financing on the property, and acquire the mortgage revenue bonds.
In June 2013, the Partnership acquired six mortgage revenue bonds secured by three properties located in San Antonio, Texas. On June 30, 2014 the Company finalized the restructuring of these six mortgage revenue bonds moving approximately $5.5 million in Series B mortgage revenue bonds to Series A mortgage revenue bonds. The par bond values reported on June 30, 2014 are as follows: approximately $7.8 million par value Series A and approximately $0.6 million par value Series B mortgage revenue bonds secured by the Avistar at the Oaks Apartments, a 156 unit multifamily apartment complex; approximately $5.4 million Series A mortgage revenue bonds secured by the Avistar on the Hills Apartments, a 129 unit multifamily apartment complex; and approximately $6.7 million Series A and approximately $0.5 million Series B mortgage revenue bonds secured by Avistar in 09 Apartments, a 133 unit multifamily apartment complex. The three Series A mortgage revenue bonds each carry an annual interest rate of 6.0% per annum and mature on August 1, 2050. The three Series B mortgage revenue bonds each carry an annual base interest rate of 9.0% per annum and mature on September 1, 2050. The Partnership also acquired approximately $831,000 of taxable mortgage revenue bonds which also carry a base interest rate of 9.0% per annum and mature on September 1, 2050. In connection with the mortgage revenue bond restructuring the Company loaned these entities approximately $526,000 to cover the costs of restructuring the mortgage revenue bonds (Note 8). The Company has determined that the entity which owns the three properties is an unrelated not-for-profit which under the accounting guidance is not subject to applying the VIE consolidation guidance. As a result, the properties’ financial statements are not consolidated into the consolidated financial statements of the Company.
In April 2013, the Partnership acquired the Series C mortgage revenue bond secured by the Renaissance Gateway Apartments, a 208 unit multifamily apartment complex located in New Orleans, Louisiana for approximately $2.9 million par value. This property is undergoing a major rehabilitation and the Partnership has agreed to fund a total of approximately $8.6 million of a Series A mortgage revenue bond during construction which is estimated to be completed in August 2014. During the third and fourth quarter of 2013, the Partnership purchased $1.3 million par value Series B and $3.9 million par value Series A mortgage revenue bonds. During the first half of 2014, the Partnership purchased an additional approximate $4.0 million par value Series A mortgage revenue bond. The Series C mortgage revenue bond carries a base interest rate of 12.0% per annum and matures on June 1, 2015. The Series A and Series B mortgage revenue bonds carry a base interest rate of 6.0% and 12.0% per annum, respectively, maturing on June 1, 2030. Upon completion of construction and stabilization, the approximate $2.9 million Series C bond will be paid back on the earlier of when the property receives its final equity contribution by the limited partner or June 1, 2015. The Partnership accounts for the remaining Bond Purchase Commitment as an available-for-sale security and, as such, records the change in estimated fair value of the Bond Purchase Commitment as an asset or liability with changes in such valuation recorded in other comprehensive income.  As of June 30, 2014, the Partnership estimated the value of this Bond Purchase Commitment and recorded an asset of approximately $4,500.
In February 2013, the Partnership acquired six mortgage revenue bonds secured by three properties located in San Antonio, Texas. On June 30, 2014 the Company finalized the restructuring of six mortgage revenue bonds moving approximately $4.7 million in Series B mortgage revenue bonds to Series A mortgage revenue bonds. The par bond values reported on June 30, 2014 are as follows: approximately $16.5 million par value Series A and approximately $0.5 million par value Series B mortgage revenue bonds secured by the Avistar on the Boulevard, a 344 unit multifamily apartment complex; approximately $10.0 million Series A and approximately $1.0 million Series B mortgage revenue bonds secured by the Avistar at Chase Hill, a 232 unit multifamily apartment complex; and approximately $9.7 million Series A and approximately $0.8 million Series B mortgage revenue bonds secured by Avistar at the Crest, a 200 unit multifamily apartment complex. The three Series A mortgage revenue bonds each carry an annual interest rate of 6.0% per annum and mature on March 1, 2050. The three Series B mortgage revenue bonds each carry an annual base interest rate of 9.0% per annum and mature on April 1, 2050. The Partnership also acquired approximately $804,000 of taxable mortgage revenue bonds which also carry a base interest rate of 9.0% per annum and mature on April 1, 2050. The Company has determined that the entity which owns the three Avistar properties is an unrelated not-for-profit which under the accounting guidance is not subject to applying the VIE consolidation guidance. As a result, the properties’ financial statements are not consolidated into the consolidated financial statements of the Company.
Under the terms of a Bond Purchase Commitment, the Partnership has agreed to purchase a new mortgage revenue bond of between $20,638,000 and $26,687,000 (“Judson Series B Bond”) secured by the Vantage at Judson apartments which will be delivered by the mortgage revenue bond issuer once the property meets specific obligations and occupancy rates. The final amount of the Series B Bond will depend on the appraisal of the stabilized property. The Judson Series B Bond will have a stated annual interest rate of 6.0% per annum and bond proceeds must be used to pay off the construction loan to the Bank and all or a portion of the $6,049,000 subordinate mortgage revenue bond. If the property does not meet its specific obligations and required occupancy rate before January 1, 2015, the Partnership has the right to terminate the Bond Purchase Commitment. As of June 30, 2014, the Partnership estimated the value of this Bond Purchase Commitment and recorded an asset of approximately $154,000.
Valuation - As all of the Company’s investments in mortgage revenue bonds are classified as available-for-sale securities, they are carried on the balance sheet at their estimated fair values.  Due to the limited market for the mortgage revenue bonds, these estimates of fair value do not necessarily represent what the Company would actually receive in a sale of the mortgage revenue bonds.  There is no active trading market for the mortgage revenue bonds and price quotes for the mortgage revenue bonds are not generally available.  As of June 30, 2014, all of the Company’s mortgage revenue bonds were valued using discounted cash flow and yield to maturity analyses performed by management.  Management’s valuation encompasses judgment in its application.  The key assumption in management’s yield to maturity analysis is the range of effective yields on the individual mortgage revenue bonds.  The effective yield analysis for each mortgage revenue bond considers the current market yield on similar mortgage revenue bonds as well as the debt service coverage ratio of each underlying property serving as collateral for the mortgage revenue bond. At June 30, 2014, the range of effective yields on the individual mortgage revenue bonds was 5.6% to 9.1% per annum.  At December 31, 2013, the range of effective yields on the individual mortgage revenue bonds was 6.3% to 9.8% per annum. Additionally, the Company calculated the sensitivity of the key assumption used in calculating the fair values of these mortgage revenue bonds.  Assuming a 10% adverse change in the key assumption, the effective yields on the individual mortgage revenue bonds would increase to a range of 6.1% to 10.0% per annum and would result in additional unrealized losses on the mortgage revenue bond portfolio of approximately $22.5 million.  This sensitivity analysis is hypothetical and is as of a specific point in time.  The results of the sensitivity analysis may not be indicative of actual changes in fair value and should be used with caution.  If available, the general partner may also consider price quotes on similar mortgage revenue bonds or other information from external sources, such as pricing services.  Pricing services, broker quotes and management’s analyses provide indicative pricing only.
Unrealized gains or losses on these mortgage revenue bonds are recorded in accumulated other comprehensive income (loss) to reflect changes in their estimated fair values resulting from market conditions and fluctuations in the present value of the expected cash flows from the underlying properties. As of June 30, 2014, the Woodlynn Village mortgage revenue bond investment has been in an unrealized loss position for greater than twelve months.  The Company has the intent and ability to hold the mortgage revenue bond until its final maturity.

	Public Housing Capital Fund Trust Certificates
	The Company owns 100% of the residual participation receipts (“LIFERs”) in three tender option bond trusts (“PHC TOB Trusts”). At June 30, 2014, the PHC TOB Trusts own approximately $63.4 million of Public Housing Capital Fund Certificates (“PHC Certificates”) issued by three trusts (“PHC Trusts”) sponsored by Deutsche Bank (“DB”). The assets held by the PHC Trusts consist of custodial receipts evidencing loans made to a number of local public housing authorities. Principal and interest on these loans are payable by the respective public housing authorities out of annual appropriations to be made to the public housing authorities by the United States Department of Housing and Urban Development (“HUD”) under HUD’s Capital Fund Program established under the Quality Housing and Work Responsibility Act of 1998 (the “Capital Fund Program”). The PHC Trusts have a first lien on these annual Capital Fund Program payments to secure the public housing authorities’ respective obligations to pay principal and interest on their loans. The loans payable by the public housing authorities are not debts of, or guaranteed by, the United States of America or HUD. Interest payable on the public housing authority debt held by the PHC Trusts is exempt from federal income taxes. The PHC Certificates issued by each of the PHC Trusts have been rated investment grade by Standard & Poor’s.
	The Company determined that the three PHC TOB trusts are variable interest entities and that the Company was the primary beneficiary of each of the three PHC TOB trusts. As a result, the Company reports the PHC TOB Trusts on a consolidated basis and the senior floating-rate participation interest (“SPEARS”) as debt financing. In determining the primary beneficiary of these specific VIEs, the Company considered who has the power to control the activities of the VIEs which most significantly impact their financial performance, the risks that the entity was designed to create, and how each risk affects the VIE. The indenture for the PHC TOB trusts stipulates that the Company has the sole right to cause the PHC TOB trusts to sell the PHC Certificates. If they were sold, the extent to which the VIEs will be exposed to gains or losses would result from decisions made by the Company.
	The Company had the following investments in the PHC Certificates on June 30, 2014:

		$	65,901,114		$	—		$	(3,844,735	)	$	62,056,379
	During the first half of 2014 the Partnership realized approximately $1.8 million of paydown related to the Public Housing Capital Fund Trust Certificates.
	Valuation - As all of the Company’s investments in PHC Certificates are classified as available-for-sale securities, they are carried on the balance sheet at their estimated fair values.  Due to the limited market for the PHC Certificates, these estimates of fair value do not necessarily represent what the Company would actually receive in a sale of the certificates.  The estimates of the fair values of these PHC certificates is based on a yield to maturity analysis which begins with the current market yield rate for a “AAA” rated tax-free municipal bond for a term consistent with the weighted-average life of each of the Public Housing Capital Fund trusts adjusted largely for unobservable inputs the General Partner believes would be used by market participants. Management’s fair value estimates encompass judgment. Management’s estimates are compared to external pricing services when available.   The PHC Certificates are AA- and BBB rated. The Company has concluded that the PHC Certificates are not other than temporarily impaired as of June 30, 2014 as it has the intent and ability to hold this investment until its final maturity.
	At June 30, 2014, the range of effective yields on the PHC Certificates was 4.2% to 5.4% per annum.  At December 31, 2013, the range of effective yields on the PHC Certificates was 4.2% to 5.4% per annum. Additionally, the Company calculated the sensitivity of the key assumption used in calculating the fair values of these PHC Certificates.  Assuming a 10% adverse change in the key assumption, the effective yields on the PHC Certificates would increase to a range of 4.8% to 6.3% per annum and would result in additional unrealized losses on the PHC Certificates of approximately $2.5 million.  This sensitivity analysis is hypothetical and is as of a specific point in time.  The results of the sensitivity analysis may not be indicative of actual changes in fair value and should be used with caution.  If available, the general partner may also consider other information from external sources, such as pricing services.  Pricing services and management’s analysis provide indicative pricing only.

Mortgage-Backed Securities [Abstract]	'
Investments in Debt and Equity Investments, Cash and Cash Equivalents, Unrealized and Realized Gains (Losses), Mortgage Backed Securities [Text Block]	'
	Mortgage-Backed Securities (“MBS”)
	Between November 2012 and April 2013, the Company executed six securitizations of mortgage-backed securities (“MBS TOB Trusts”). The Company purchased the LIFERS issued by the six MBS TOB Trusts for approximately $9.2 million.
	Each of the six MBS TOB Trusts issued SPEARS to unaffiliated investors; these SPEARS totaled approximately $34.9 million at issuance. The SPEARS represent senior interests in the MBS TOB Trusts and have been credit enhanced by DB. The LIFERS entitle the Company to all principal and interest payments received by the MBS TOB Trust on the securitized MBS after payments due to the holders of the SPEARs and trust costs. The SPEARS bear interest at a variable rate based on Securities Industry and Financial Markets Association (“SIFMA”) index.
	The Company determined that the six MBS TOB Trusts are variable interest entities and that the Company was the primary beneficiary of each of them. As a result, the Company reports the MBS TOB Trusts on a consolidated basis and the SPEARS as debt financing. In determining the primary beneficiary of these specific VIEs, the Company considered who has the power to control the activities of the VIEs which most significantly impact their financial performance, the risks that the entity was designed to create, and how each risk affects the VIE. The indenture for the MBS TOB Trusts stipulates that the Company has the sole right to cause the MBS TOB Trusts to sell the MBS. If they were sold, the extent to which the MBS TOB Trusts will be exposed to gains or losses would result from decisions made by the Company.
	In May 2014, the Company sold a portion of the MBS TOB Trusts for an amount approximating the outstanding amortized cost. This approximately $3.7 million par value MBS had been acquired for approximately $3.8 million in November 2012.
	The carrying value of the Company’s MBS as of June 30, 2014 is as follows:
	Agency Rating of MBS (1)	Cost adjusted for amortization of premium		Unrealized Gain				Unrealized Loss			Estimated Fair Value
	“AAA”	$	23,165,482	$	—			$	(955,754	)	$	22,209,728
	“AA”	16,851,823		—				(1,182,843		)	15,668,980
		$	40,017,305	$	—			$	(2,138,597	)	$	37,878,708
	(1) MBS are reported based on the lowest rating issued by a Rating Agency, if more than one rating is issued on the security, at the date presented.
	The carrying value of the Company’s MBS as of December 31, 2013 is as follows:
	Agency Rating of MBS (1)	Cost adjusted for amortization of premium		Unrealized Gain				Unrealized Loss			Estimated Fair Value
	“AAA”	$	23,177,115	$	—			$	(3,069,555	)	$	20,107,560
	“AA”	20,624,701		—				(2,886,600		)	17,738,101
		$	43,801,816	$	—			$	(5,956,155	)	$	37,845,661
	(1) MBS are reported based on the lowest rating issued by a Rating Agency, if more than one rating is issued on the security, at the date presented.
	Valuation - The Company values each MBS based upon prices obtained from a third party pricing service, which are indicative of market activity. The valuation methodology of the Company’s third party pricing service incorporates commonly used market pricing methods, incorporates trading activity observed in the market place, and other data inputs. The methodology also considers the underlying characteristics of each security, which are also observable inputs, including: coupon; maturity date; loan age; reset date; collateral type; geography; and prepayment speeds. Management analyzes pricing data received from the third party pricing service by comparing it to valuation information obtained from at least one other third party pricing service and ensuring they are within a tolerable range of difference which the Company estimates as 7.5%. Management also looks at observations of trading activity observed in the market place when available. At June 30, 2014 and December 31, 2013, the range of effective yields on the individual MBS was 3.6% to 5.4% per annum.  Additionally, the Company calculated the sensitivity of the key assumption used in calculating the fair values of the MBS which is the effective yield on new issuances of similarly rated MBS.  Assuming a 10% adverse change in that key assumption, the effective yields on the MBS would increase to a range of 3.8% to 5.4% per annum and would result in additional unrealized losses on the bond portfolio of approximately $1.9 million.  This sensitivity analysis is hypothetical and is as of a specific point in time.  The results of the sensitivity analysis may not be indicative of actual changes in fair value and should be used with caution.  Pricing services and management’s analysis provide indicative pricing only. The MBS have been in an unrealized loss position for more than twelve months and the Company does not believe the investment is other than temporarily impaired as of June 30, 2014 as it has the intent and ability to hold these investments until their estimated fair value recovers to the carrying cost or until final maturity.
	The MBS are backed by residential mortgage loans and interest payable from the MBS is exempt from federal income taxation. Description of certain terms of the Company’s MBS is as follows:
	Agency Rating of MBS	Principal Outstanding June 30, 2014		Weighted Average Maturity Date		Weighted Average Coupon Interest Rate
	“AAA”	$	22,710,000	October 7, 2036		4.05	%
	“AA”	16,440,000		January 18, 2036		4.11	%

	MF Properties
	To facilitate its investment strategy of acquiring additional mortgage revenue bonds secured by MF Properties, the Company has acquired through its various subsidiaries 99% limited partner positions in three limited partnerships and 100% member positions in six limited liability companies that own the MF Properties. The financial statements of these properties are consolidated with those of the Company.  The general partners of these partnerships are unaffiliated parties and their 1% ownership interest in these limited partnerships is reflected in the Company’s consolidated financial statements as noncontrolling interests. The Company expects each of these MF Properties to eventually be sold either to a not-for-profit entity or in connection with a syndication of LIHTCs. The Company expects to purchase mortgage revenue bonds issued by the new property owners as part of the restructuring.
	Recent Transactions
	The Partnership, as sole bondholder, previously directed the bond trustee to file a foreclosure action on the Woodland Park mortgage revenue bond. On February 28, 2013, the court granted Summary Judgment in the bond trustee’s favor confirming that the mortgage revenue bond is senior to mechanic’s liens filed on the property. Woodland Park became an MF Property at a net asset value of approximately $15.7 million upon conveyance of title on May 29, 2013. The Partnership requested the mortgage revenue bond issuer to remove the LURA on the property and the units have been converted to 100% market-rate rents. The Partnership may convert the property back to a rent restricted property, seek to place new financing on the property, and acquire the mortgage revenue bonds.
	In March 2013, a wholly-owned subsidiary of the Company executed a 35-year ground lease with the University of Nebraska - Lincoln (“Lessor”) with an annual lease payment of $100. The leased property will have a mixed-use development consisting of a 1,605 stall parking garage and 475 bed student housing complex constructed on it. The Lessor will own the parking garage for which it will contribute approximately $16.7 million to its construction. The Company will own the student housing complex (named “The 50/50”) and currently estimates that construction will cost approximately $34.0 million. The Company executed a guaranteed maximum price contract with the general contractor for the construction on the mixed-use development. The Company expects to restructure its ownership of The 50/50 into a mortgage revenue bond holding after the construction is completed (which is estimated as August 1, 2014) and when the development has a sufficient history of operating results. To finance the construction of the student housing complex, the Company has executed an interest-only loan to borrow up to $25.5 million for a three year term at a variable interest rate. The Company also secured a $4.3 million tax-incremental financing loan which is for a term of five years, carries a fixed interest rate of approximately 4.7% per annum, requires principal payments commencing after 24 months and has a balloon payment due at maturity. The Company has borrowed approximately $21.8 million on this facility as of June 30, 2014 (Notes 11).

	In addition to the mortgage revenue bonds held by the Company, taxable property loans have been made to the owners of the properties which secure the mortgage revenue bonds and are reported as taxable property loans receivable in Other assets, net of loan loss reserves.  The Company periodically, or as changes in circumstances or operations dictate, evaluates such taxable property loans receivable for impairment.  The value of the underlying property assets is ultimately the most relevant measure of value to support the taxable property loan values.  The Company utilizes a discounted cash flow model in estimating a property fair value.  Discounted cash flow models containing varying assumptions are considered.   The various models may assume multiple revenue and expense scenarios, various capitalization rates and multiple discount rates.  Other information, such as independent appraisals, may be considered in estimating a property’s fair value.  If the estimated fair value of the property after deducting the amortized cost basis of any senior mortgage revenue bond exceeds the principal balance of the taxable property loan then no potential loss is indicated and no loan loss reserve for taxable property loans is needed. In estimating the property valuation, the most significant assumptions utilized in the discounted cash flow model remain the same as discussed in the Form 10-K and include revenue and expense projections and capitalization rates.
	On June 30, 2014, the Company restructured twelve mortgage revenue bonds related to Avistar on the Boulevard, Avistar at Chase Hill, Avistar at the Crest, Avistar on the Hills Apartments, Avistar at the Oaks Apartments, and Avistar in 09 Apartments purchased in June and February 2013 (Note 4). In connection with the mortgage revenue bond restructuring the Company loaned these entities approximately $526,000 to cover the costs of restructuring the mortgage revenue bonds. These taxable loans have a stated interest rate of 12.0% per annum due monthly with any unpaid balance due on June 26, 2024 (Note 4).
	On November 26, 2013, the Company executed a loan agreement with Foundation for Affordable Housing, a not-for-profit borrower, for approximately $1.6 million. The proceeds from this loan were used to fund a portion of the not-for-profit borrower’s acquisition of Abbington at Stones River, a 96 unit multifamily property located in Tennessee. The term of the loan is approximately eighteen months and the stated interest rate is 9.0% per annum.
	In August 2013, the Partnership acquired a Series C mortgage revenue bond and a forward contract to support the construction of Vantage at Harlingen Apartments in Harlingen, Texas. In conjunction with this contract, the Partnership acquired an approximate $1.3 million taxable mortgage revenue bond which carries a base interest rate of 9.0% per annum and matures on August 1, 2053. This taxable mortgage revenue bond is reported as part of the Taxable bonds at fair value in Other assets. Please see the Fair Value Measurement footnote (Note 15) for the detailed description of the fair value estimation process for the taxable mortgage bonds.
	In June 2013, the Partnership acquired six mortgage revenue bonds secured by three properties located in San Antonio, Texas, Avistar at the Oaks Apartments, Avistar on the Hills Apartments, and Avistar in 09 Apartments. The Partnership also acquired approximately $831,000 of taxable mortgage revenue bonds which carry a base interest rate of 9.0% per annum and mature on September 1, 2050. These are reported as part of the Taxable bonds at fair value in Other assets.
	In February 2013, the Partnership acquired six mortgage revenue bonds secured by three properties located in San Antonio, Texas, Avistar on the Boulevard, Avistar at Chase Hill, and Avistar at the Crest. The Partnership also acquired approximately $804,000 of taxable mortgage revenue bonds which carry a base interest rate of 9.0% per annum and mature on April 1, 2050. These are reported as part of the Taxable bonds at fair value in Other assets.
	During the first half of 2014, the Partnership advanced additional funds to Cross Creek and the Ohio Properties of approximately $67,000 and $29,000, respectively. During the first half of 2013, the Partnership advanced additional funds to Ashley Square, Cross Creek and the Ohio Properties of approximately $118,000, $96,000, and $42,000, respectively. Due to the recognized sale of the Ohio and Greens Properties, the taxable property loans receivable with the Ohio and Greens Properties are no longer eliminated upon consolidation (Note 9). During the first half of 2014 and 2013, the Partnership recorded loan loss reserves equal to the accrued interest on the Ashley Square, Cross Creek, Greens and the Ohio Properties taxable property loans receivable because the Partnership determined they were not reasonably assured. The Partnership also reserved against the $96,000 advanced to the Cross Creek property in 2013 based on the quarterly impairment analysis.
	The following is a summary of the taxable property loans receivable, accrued interest and loan loss reserves on the amounts due at June 30, 2014 and December 31, 2013, respectively:

	Discontinued Operations
	In June 2010, the Company completed a sales transaction whereby the Ohio Properties were sold to three new ownership entities controlled by an unaffiliated not-for-profit entity and in October 2011, the three limited partnerships that own the Ohio Properties admitted two entities that are affiliates of BC Partners as new limited partners as part of a syndication of LIHTCs. The BC Partners agreed to contribute equity to these limited partnerships, subject to the Ohio Properties meeting certain debt service coverage ratios specified in the applicable limited partnership agreements. As such, there was not sufficient equity invested at closing by the not-for-profit or BC Partners into the Ohio Properties to allow the Company to recognize a real estate sale for accounting purposes. During the first quarter of 2013, BC Partners contributed $6.5 million of capital into the Ohio Properties which was sufficient to allow the Company to recognize the sale for accounting purposes. This gain on sale of discontinued operations was approximately $1.8 million.
	The deposit method of accounting for real estate sales required deferral of the gain from the real estate sale and did not allow recognition of the interest payments by the Ohio Properties to the Company between June 2010 and the date of the equity contribution by BC Partners. In conjunction with the recognition of the real estate sale, approximately $3.5 million of interest was recognized within investment income in the first three months of 2013 which represents the interest payments received from the Ohio Properties between June 2010 and December 2012. In addition, the Partnership reported approximately $1.1 million in taxable note interest income received from the Ohio Properties and a $250,000 guarantee fee from the general partner of the Ohio Properties during the first quarter of 2013. Due to the deposit method of accounting, the Company recognized the sale of the Ohio Properties and the purchase of the mortgage revenue bonds they secure in the consolidated statement of cash flows during the first quarter of 2013. The Ohio Properties contributed approximately $0 and $138,000 to income from discontinued operations for the three and six months ended June 30, 2013.
	In October 2012, the limited partnership that owns the Greens Property admitted two entities that are affiliates of BC Partners as new limited partners as part of a syndication of LIHTCs on the Greens Property. Prior to the execution of the admittance of the new limited partners, the Company had entered into an agreement to sell the Greens Property for approximately $7.3 million to an unaffiliated not-for-profit which is the general partner of the limited partnership that now owns the Greens Property.  That sale was conditional on securing the mortgage revenue bond and low-income housing tax credits from the North Carolina Housing Finance Agency.  The $961,000 BC Partners equity contribution into this limited partnership in October 2012 was not sufficient to allow the Company to recognize a real estate sale for accounting purposes. In July 2013, BC Partners made their required $800,000 capital contribution into the Greens Property as construction was then 75% complete.
	The Company purchased 100% of the mortgage revenue bonds issued as part of the agreement to finance the acquisition and rehabilitation of the Greens Property. The Series A mortgage revenue bond has approximately $8.5 million par value and bears interest at 6.5% per annum. The Series B mortgage revenue bond has a $950,000 par value and bears interest at 12.0% per annum. Both series of mortgage revenue bonds mature on October 1, 2047. The Company also obtained an $850,000 taxable property loan secured by the Greens Property at closing.
	The July 2013 equity payment provided sufficient invested equity to recognize a real estate sale for accounting purposes and the Company recorded the sale of this discontinued operation. This gain on sale of discontinued operations was approximately $1.4 million. The deposit method of accounting for real estate sales required the deferral of the gain from the real estate sale and did not allow recognition of the interest payments by the Greens Property to the Company between October 2012 and July 2013, the date of the second equity contribution by BC Partners. In conjunction with the recognition of the real estate sale, approximately $523,000 of interest was recognized within investment income in the third quarter of 2013 which represents the interest payments received from the Greens Property between October 2012 and July 31, 2013. The Greens Property contributed a loss from discontinued operations of approximately $167,000 and $325,000 for the three and six months ended June 30, 2013, respectively.
	There were no assets and liabilities of discontinued operations to report at June 30, 2014 and December 31, 2013.

	Debt Financing
	At June 30, 2014 and December 31, 2013, the Company reported outstanding debt financing of approximately $244.5 million and approximately $257.3 million, respectively, under separate credit facilities.
	Other Financings
	In March 2014, the Partnership obtained two $5.0 million unsecured revolving lines of credit. The first revolving line of credit carries a variable interest rate which was approximately 3.5% at date of closing and matures in March 2015. The second revolving line of credit also carries a variable interest rate which was approximately 3.4% on June 30, 2014 and matures in March 2016. On June 30, 2014, the Partnership had not borrowed funds on either line of credit. The lines of credit will be utilized to help with short-term working capital needs and to fund new investments during the periods of time that the Company is working with its lender to finalize new TOB financings of assets.

	(2) Avistar at Chase Hill, Avistar at the Crest, and Avistar on the Boulevard is the collateral for the approximate $13.2 million TOB Trust.
	In July 2011, the Company executed a Master Trust Agreement with DB which allows the Company to execute multiple Tender Option Bond (“TOB Trust”) structures upon the approval and agreement of terms by DB. Under each TOB Trust structure issued through the Master Trust Agreement, the TOB trustee issues SPEARS and LIFERS. These SPEARS and LIFERS represent beneficial interests in the securitized asset held by the TOB trustee. The Company will purchase the LIFERS from each of these TOB Trusts which will grant them certain rights to the securitized assets. The Master Trust Agreement with DB has covenants with which the Company is required to comply. At June 30, 2014, the most restrictive covenant was that cash available to distribute for the trailing twelve months must be at least two times trailing twelve month interest expense. The Company was in compliance with all covenants as of June 30, 2014. If the Company were to be out of compliance with any of these covenants, it would trigger a termination event of the financing facilities. The Company expects to renew each of the TOB financing facilities at its discretion per the terms of the agreements. DB can require the posting of cash collateral under the terms of the Master Trust Agreement.
	In March 2014, the Company executed a new TOB Trust under its credit facility with DB securitizing the Decatur-Angle mortgage revenue bond borrowing $17.3 million. The facility has a variable interest rate tied to SIFMA and matures in February 2015. On the date of closing the total fixed TOB Trust fee was approximately 1.5% per annum and the variable rate paid on the TOB Trust on the SPEARS was approximately 0.3% resulting in a total cost of borrowing of approximately 1.8%. The outstanding balance remains at approximately $17.3 million on June 30, 2014. In July 2014, the Company entered into a new TOB Trust which replaces this TOB Trust (Note 18).
	In December 2013, the Company executed a new TOB Trust under its credit facility with DB securitizing The Suites on Paseo Series A mortgage revenue bond. The amount borrowed was approximately $25.8 million with a variable interest rate tied to SIFMA. The facility matures in December 2014. On the date of the closing the total fixed TOB Trust fee was approximately 1.6% per annum and the variable rate paid on the TOB Trust on the SPEARS was approximately 0.4% per annum resulting in a total cost of borrowing of approximately 2.0% per annum. The outstanding balance remains at approximately $25.8 million on June 30, 2014.
	In October 2013, the Company executed a new TOB Trust under its credit facility with DB securitizing the Avistar at the Oaks Apartments, the Avistar on the Hills Apartments, and the Avistar in 09 Apartments Series A mortgage revenue bonds. The amount borrowed was approximately $13.2 million with a variable interest rate tied to SIFMA. On the date of the closing the total fixed TOB Trust fee was approximately 1.8% per annum and the variable rate paid on the TOB Trust on the SPEARS was approximately 0.4% per annum resulting in a total cost of borrowing of approximately 2.2% per annum. The outstanding balance remains at $13.2 million on June 30, 2014. This TOB Trust was settled in July 2014 (Note 18).
	In June 2013, the Company executed a new TOB Trust under its credit facility with DB securitizing the Avistar on the Boulevard, Avistar at Chase Hill, and Avistar at the Crest Series A mortgage revenue bonds. The amount borrowed was $20.0 million with a variable interest rate tied to SIFMA. On the date of closing the total fixed TOB Trust fee was approximately 2.1% per annum and the variable rate paid on the TOB Trust on the SPEARS was approximately 0.4% resulting in a total cost of borrowing of approximately 2.5%. The outstanding balance remains at $20.0 million on June 30, 2014. This TOB Trust was settled in July 2014 (Note 18).
	In March 2013, the Company executed a new TOB Trust under its credit facility with DB securitizing the Arbors at Hickory Ridge mortgage revenue bond. The amount borrowed was $7.0 million with a variable interest rate tied to SIFMA. On the date of closing the total fixed TOB Trust fee was approximately 2.1% per annum and the variable rate paid on the TOB Trust on the SPEARS was approximately 0.5% resulting in a total cost of borrowing of approximately 2.6%. The outstanding balance remains at $7.0 million on June 30, 2014. This TOB Trust was settled in July 2014 (Note 18).
	In February 2013, the Company executed a new TOB Trust under its credit facility with DB securitizing the Greens Property mortgage revenue bond. The amount borrowed was approximately $5.8 million with a variable interest rate tied to SIFMA. On the date of closing the total fixed TOB trust fee was approximately 2.1% per annum and the variable rate paid on the TOB Trust on the SPEARS was approximately 0.5% resulting in a total cost of borrowing of approximately 2.6%. The outstanding balance was $5.7 million on June 30, 2014. This TOB Trust was settled in July 2014 (Note 18).
	In the fourth quarter of 2012 through the second quarter of 2013, the Company purchased the LIFERS issued by the trustee of six additional TOB Trusts. The LIFERS entitle the Company to all principal and interest payments received by these TOB Trusts on the mortgage-backed securities after payments due to the holders of the SPEARS and trust costs (“MBS TOB Trusts”). The SPEARS represent senior interests in the MBS TOB Trusts and some have been credit enhanced by DB. The Company reports the MBS TOB Trusts on a consolidated basis as it has determined it is the primary beneficiary of these variable interest entities (Note 6). A summary of the six MBS TOB Trusts is as follows:
	•	During the fourth quarter of 2012, the Company purchased approximately $6.5 million of LIFERS from securitized MBS TOB Trusts with a par value of approximately $31.6 million of MBS. The MBS TOB Trusts also issued SPEARS of approximately $25.1 million to unaffiliated investors. The approximate outstanding amount at June 30, 2014 is $21.2 million which mature in October 2014. On the date of closing the total fixed TOB Trust fee was approximately 0.9% per annum and the variable rate paid on the SPEARS of approximately 0.4% is tied to SIFMA which results in the total cost of borrowing of approximately 1.3%.
	•	In January 2013, the Company purchased an additional $540,000 of LIFERS from one of the five MBS TOB Trusts which is a securitization of MBS with a par value of $2.5 million. SPEARS of approximately $2.0 million were issued by the MBS TOB Trust which is currently outstanding at June 30, 2014. This MBS TOB Trust matures in October 2014. On the date of closing the total fixed TOB Trust fee was approximately 0.9% per annum and the variable rate paid on the SPEARS of approximately 0.3% is tied to SIFMA which results in the total cost of borrowing of approximately 1.2%.
	•	In April 2013, the Company purchased approximately $2.2 million of LIFERS issued by a new MBS TOB Trust which is the securitization of MBS with a par value of approximately $10.0 million. The MBS TOB Trusts issued SPEARS of approximately $7.8 million to unaffiliated investors which is the outstanding amount at June 30, 2014. This facility matures in August 2014. On the date of closing the total fixed TOB Trust fee was approximately 0.9% per annum and the variable rate paid on the SPEARS of approximately 0.3% is tied to SIFMA which results in the total cost of borrowing of approximately 1.2%.
	In May 2014, the Company sold a portion of the MBS and collapsed the related MBS - TOB Trust 3 securitizing the related MBS for approximately $3.7 million. The Company’s $2.9 million TOB financing facility, which was the securitization of this MBS TOB Trust, was paid off in full in connection with this sale. .
	In April 2014, the mortgage revenue bond secured by Autumn Pines was sold for approximately $13.1 million. The Company’s $9.8 million TOB financing facility, which was the securitization of this mortgage revenue bond, was collapsed and paid off in full in connection with this sale (Note 4).
	As of June 30, 2014, the Company has posted approximately $2.5 million of cash collateral in connection with the MBS TOB Trusts. This collateral is recorded as restricted cash in the consolidated financial statements.
	The Company owns the PHC Certificate LIFERS issued by the PHC TOB Trusts and pledged the LIFERS to the trustee to secure certain reimbursement obligations of the Company as the holder of LIFERS. The Company is consolidating the PHC TOB Trust as it has determined it is the primary beneficiary of these variable interest entities. The PHC TOB Trusts issued SPEARS to unaffiliated investors. The SPEARS represent senior interests in the PHC TOB Trusts and have been credit enhanced by DB. The LIFERS entitle the Company to all principal and interest payments received by the PHC TOB Trusts. Approximately $1.3 million was paid to reduce the outstanding balance during the first half of 2014. The amount owed to the SPEARS owners is approximately $47.8 million at June 30, 2014.
	The Company is accounting for these TOB Trust financing transactions as secured financing arrangements. As of June 30, 2014, the total cost of borrowing averaged approximately 2.3% and 1.1%, on the PHC TOB Trusts and MBS TOB Trusts, respectively.
	2010 TEBS Financing
	As of September 1, 2010, the Partnership and its Consolidated Subsidiary ATAX TEBS I, LLC, entered into a number of agreements relating to a new long-term debt financing facility provided through the securitization of thirteen mortgage revenue bonds owned by the ATAX TEBS I, LLC (the “Sponsor”) pursuant to the 2010 TEBS financing. The 2010 TEBS financing essentially provides the Partnership with a long-term variable-rate debt facility at interest rates reflecting prevailing short-term rates. In January 2014, the mortgage revenue bond secured by Lost Creek was retired for an amount greater than the outstanding principal and accrued base interest. The Company received approximately $18.7 million for the Lost Creek mortgage revenue bond and paid approximately $15.7 million to reduce the outstanding balance of the 2010 TEBS financing facility (Note 4), therefore at June 30, 2014 there are twelve mortgage revenue bonds owned by the Sponsor.
	The par value of the mortgage revenue bonds included in this financing facility as of June 30, 2014 and December 31, 2013 are as follows:

(1) Collateralized by Crescent Village, Postwoods, and Willow Bend (Note 2 and Note 9)
The securitization of these assets occurred through two classes of certificates. The Class A TEBS Certificates were issued in an initial principal amount of $95.8 million and were sold through a placement agent to unaffiliated investors. The Class B TEBS Certificates were issued in an initial principal amount of $20.3 million and were retained by the Sponsor. The holders of the Class A TEBS Certificates are entitled to receive regular payments of interest from Freddie Mac at a variable rate which resets periodically based on the weekly SIFMA floating index rate plus certain credit, facility, remarketing and servicing fees (the “Facility Fees”).
The total Facility Fees are 1.9% per annum, and as of June 30, 2014, the SIFMA rate was equal to approximately 0.1% resulting in a total cost of borrowing of approximately 2.0% on the outstanding balance of the 2010 TEBS financing facility of $77.2 million. The 2010 TEBS financing and the associated TEBS Trust are presented as secured financings within the consolidated financial statements.
The term of the 2010 TEBS financing coincides with the terms of the assets securing the TEBS Certificates, except that the Partnership may terminate the 2010 TEBS financing at its option on either September 15, 2017 or September 15, 2020. If the Partnership does not elect to terminate the 2010 TEBS financing on these dates, the full term of the 2010 TEBS financing runs through the final principal payment date associated with the securitized mortgage revenue bonds, or July 15, 2050.
The Company’s debt financing as of June 30, 2014 contractually matures over the next five years and thereafter as follows:
2014		$	150,774,000
2015		18,160,000
2016		949,000
2017		74,585,000
2018		—
Thereafter		—
Total		$	244,468,000
In July 2014, the Company sold the LIFERS and retired the MBS TOB Trusts securitized by the SPEARS that came due in June 2014 (Note 18).

	The general partner of the Partnership, AFCA 2, is entitled to receive an administrative fee from the Partnership equal to 0.45% per annum of the outstanding principal balance of any of its mortgage revenue bonds, taxable property loans collateralized by real property, and other investments for which the owner of the financed property or other third party is not obligated to pay such administrative fee directly to AFCA 2. For the three and six months ended June 30, 2014 the Partnership paid or accrued administrative fees to AFCA 2 of approximately $471,000 and $944,000, respectively. For the three and six months ended June 30, 2013 the Partnership paid or accrued administrative fees to AFCA 2 of approximately $370,000 and $712,000, respectively. In addition to the administrative fees paid directly by the Partnership, AFCA 2 receives administrative fees directly from the owners of properties financed by certain of the mortgage revenue bonds held by the Partnership.  These administrative fees also equal 0.45% per annum of the outstanding principal balance of these mortgage revenue bonds and totaled approximately $17,000 and $34,000 for the three and six months ended June 30, 2014, respectively. For the three and six months ended June 30, 2013, these fees totaled approximately $33,000 and $66,000, respectively.
	AFCA 2 earns mortgage placement fees in connection with the acquisition of certain mortgage revenue bonds.  These mortgage placement fees were paid by the owners of the respective properties and, accordingly, have not been reflected in the accompanying condensed consolidated financial statements because these properties are not considered VIEs.  During the three and six months ended June 30, 2014 AFCA 2 earned mortgage placement fees of approximately $403,000 and $726,000 , respectively. During the three and six months ended June 30, 2013, AFCA 2 earned mortgage placement fees of approximately $470,000 and $862,000, respectively.
	An affiliate of AFCA 2, America First Properties Management Company, LLC (“Properties Management”) provided property management services for the eight MF Properties, the two Consolidated VIEs and six of the properties collateralized by the mortgage revenue bonds, earning management fees of approximately $315,000 and $634,000 for the three and six months ended June 30, 2014, respectively. Properties Management provided property management services for eight MF Properties, the three VIEs, the six properties classified as discontinued operations and four of the properties collateralized by the mortgage revenue bonds, earning management fees of approximately $305,000 and $608,000 for the three and six months ended June 30, 2013, respectively.  These property management fees are not Partnership expenses, but are paid in each case by the owner of the multifamily apartment property.  For properties owned by entities treated as Consolidated VIEs and for MF Properties, the property management fees are reflected as real estate operating expenses on the Company’s condensed consolidated financial statements.  The property management fees are paid out of the revenues generated by all properties financed by mortgage revenue bonds and taxable mortgages prior to the payment of debt service on the Partnership’s mortgage revenue bonds and taxable property loans.
	The Partnership executed a Developer and Construction Management Agreement with two affiliates of AFCA 2 during the second quarter of 2013 in connection with the mixed-use development at the University of Nebraska - Lincoln (Note 7). Under the terms of this agreement, these affiliates received approximately $56,000 and $168,000 in the first three and six months of 2014. An affiliate of AFCA 2 acts as a placement advisor to the borrowers under the mortgage revenue bonds at the time they are acquired by the Company. Any and all advisory fees are paid by the borrower of the respective bonds and, accordingly, have not been reflected in the accompanying consolidated financial statements.
	Two of the owners of the limited-purpose corporations which own two of the Consolidated VIEs held by the Company are employees of Burlington who are not involved in the operation or management of the Company and who are not executive officers or managers of Burlington.

	Interest Rate Derivative Agreements
	As of June 30, 2014, the Company has six derivative agreements in order to mitigate its exposure to increases in interest rates on its variable-rate debt financing. The terms of the derivative agreements are as follows:
		Date Purchased	Notional Amount		Effective Capped Rate		Maturity Date	Purchase Price		Counterparty
		September 2, 2010	$	31,936,667	3	%	September 1, 2017	$	921,000	Bank of New York Mellon
		September 2, 2010	$	31,936,667	3	%	September 1, 2017	$	845,600	Barclays Bank PLC
		September 2, 2010	$	31,936,667	3	%	September 1, 2017	$	928,000	Royal Bank of Canada
		August 15, 2013	$	93,305,000	1.5	%	September 1, 2017	$	793,000	Deutsche Bank
		February 18, 2014	$	41,250,000	1	%	March 1, 2017	$	230,500	SMBC Capital Markets, Inc
		February 18, 2014	$	28,750,000	1	%	March 1, 2017	$	161,000	SMBC Capital Markets, Inc
	In February 2014, the Company entered into two interest rate cap agreements with SMBC Capital Markets, Inc. for a notional amount of $70.0 million with an effective start date of March 1, 2014. These agreements effectively limit the interest component of the TOB financing correlated with the SIFMA index to a maximum of 1.0% on $70.0 million of the outstanding borrowings on the MBS TOB financing facilities and the PHC Certificates TOB financing facilities through a three year term ending March 1, 2017. These interest rate cap contracts cost approximately $390,000 and do not qualify for hedge accounting, therefore, changes in the estimated fair value of the interest rate derivatives are included in earnings.
	On July 30, 2013, the Company purchased a new interest rate derivative with a notional amount of $93.3 million which represented the amount outstanding on the 2010 TEBS financing facility at August 1, 2013.  The maturity date of this interest rate derivative is September 1, 2017 and the effective capped interest rate is 1.5%.  On July 30, 2013, the Company also sold a new interest rate derivative to the same counterparty which had the same notional amount of $93.3 million and an effective capped interest rate of 3.0%.  The total cost of these two interest rate derivatives was approximately $800,000 and the derivative contracts do not qualify for hedge accounting, therefore, changes in the estimated fair value of the interest rate derivatives are included in earnings.  This interest rate corridor transaction effectively reduced the capped interest rate from 3.0% to 1.5% on the 2010 TEBS financing facility through the maturity date of the interest rate derivative contracts. In August 2013, the Company executed a master netting agreement with DB, which is the counterparty to these interest rate derivative contracts and is also the provider of the Company’s TOB financing facilities. The Company received $500,000 of cash collateral upon the execution of this master netting agreement. This $500,000 has been reported on a net basis against the cash collateral posted for the TOB financing facilities in the consolidated balance sheet as of June 30, 2014 and December 31, 2013.
	These interest rate derivatives do not qualify for hedge accounting and, accordingly, they are carried at fair value, with changes in fair value included in current period earnings within interest expense. The change in the fair value of these derivative contracts resulted in an increase in interest expense of approximately $434,000 and $610,000 for the three and six months ended June 30, 2014, respectively. The change in the fair value of these derivative contracts resulted in a decrease in interest expense of approximately $241,000 and $136,000 for the three and six months ended June 30, 2013, respectively. The valuation methodology used to estimate the fair value of the Company’s interest rate derivative agreements is disclosed in footnote 15.

Fair Value Measurements [Abstract]	'
Fair Value Disclosures [Text Block]	'
	Fair Value Measurement
	Current accounting guidance on fair value measurements establishes a framework for measuring fair value and provides for expanded disclosures about fair value measurements.  The guidance:
	•	Defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date; and
	•	Establishes a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date.
	Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk.  To increase consistency and comparability in fair value measurements and related disclosures, the fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels.  The three levels of the hierarchy are defined as follows:
	•	Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities.
	•	Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
	•	Level 3 inputs are unobservable inputs for asset or liabilities.
	The categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
	Following is a description of the valuation methodologies used for assets and liabilities measured at fair value.
	Investments in Mortgage Revenue Bonds.  The fair values of the Company’s investments in mortgage revenue bonds have each been based on a discounted cash flow or yield to maturity analysis. The Company uses this same valuation methodology to estimate the fair value adjustment for its mortgage bond purchase commitments. There is no active trading market for the mortgage revenue bonds and price quotes for the mortgage revenue bonds are not available.  If available, the General Partner may also consider price quotes on similar mortgage revenue bonds or other information from external sources, such as pricing services.  The estimates of the fair values of these mortgage revenue bonds, whether estimated by the Company or based on external sources, are based largely on unobservable inputs the General Partner believes would be used by market participants.  Additionally, the calculation methodology used by the external sources and the Company encompasses the use of judgment in its application. To validate changes in the fair value of the Company’s investments in mortgage revenue bonds between reporting periods, the General Partner looks at the key inputs such as changes in the current market yields on similar bonds as well as changes in the operating performance of the underlying property serving as collateral for each bond. The General Partner validates that the changes in the estimated fair value of the mortgage revenue bonds move with the changes in these monitored factors. Given these facts the fair value measurement of the Company’s investment in mortgage revenue bonds is categorized as a Level 3 input. There is also an approximately $1.7 million and $5.2 million estimated fair market value adjustment related to forward bond purchase commitments that are categorized as a Level 3 input which were recorded in other comprehensive income (loss) during the three and six months ended June 30, 2014, respectively. The fair value of the bond purchase commitment is determined in the same manner as the mortgage revenue bonds.
	Investments in Public Housing Capital Fund Trust Certificates. The fair value of the Company’s investment in Public Housing Capital Fund Trust Certificates has been based on a yield to maturity analysis performed by the General Partner. There is no active trading market for the trusts’ certificates owned by the Company, but the General Partner will look at estimated values as determined by pricing services when available. The estimates of the fair values of these trusts’ certificates begin with the current market yield rate for a “AAA” rated tax-free municipal bond for a term consistent with the weighted-average life of each of the Public Housing Capital Fund trusts, adjusted largely for unobservable inputs the General Partner believes would be used by market participants. Additionally, the calculation methodology used by external pricing services and the Company encompasses the use of judgment in its application. The General Partner validates that the changes in the estimated fair value of Public Housing Capital Fund Trust Certificates move with the changes in the market yield rates of investment grade rated mortgage revenue municipal bonds with terms of similar length. Given these facts the fair value measurement of the Company’s investment in Public Housing Capital Fund Trust Certificates is categorized as a Level 3 input.
	Investments in Mortgage-Backed Securities. The fair value of the Company’s investment in mortgage-backed securities is based upon prices obtained from a third party pricing service, which are indicative of market activity. The valuation methodology of the Company’s third party pricing service incorporates commonly used market pricing methods, incorporates trading activity observed in the market place, and other data inputs. The methodology also considers the underlying characteristics of each security, which are also observable inputs, including: coupon; maturity date; loan age; reset date; collateral type; geography; and prepayment speeds. The General Partner analyzes pricing data received from the third party pricing service by comparing it to valuation information obtained from at least one other third party pricing service, ensuring they are within a tolerable range of difference which the Company estimates as 7.5%. The General Partner also looks at observations of trading activity in the market place when available. Given these facts, the fair value measurements of the Company’s investment in mortgage-backed securities are categorized as Level 2 inputs.
	Taxable Bonds. The fair values of the Company’s investments in taxable bonds have each been based on a discounted cash flow or yield to maturity analysis. There is no active trading market for the taxable bonds and price quotes are not available. The estimates of the fair values of these taxable bonds, whether estimated by the Company or based on external sources, are based largely on unobservable inputs the General Partner believes would be used by market participants.  Additionally, the calculation methodology used by the external sources and the Company encompasses the use of judgment in its application. To validate changes in the fair value of the Company’s investments in taxable bonds between reporting periods, management looks at the key inputs such as changes in the current market yields on similar bonds as well as changes in the operating performance of the underlying property serving as collateral for each bond. We validate that the changes in the estimated fair value of the taxable bonds move with the changes in these monitored factors. Given these facts the fair value measurement of the Company’s investment in taxable bonds is categorized as a Level 3 input.
	Interest Rate Derivatives.  The effect of the Company’s interest rate caps is to set a cap, or upper limit, on the base rate of interest paid on the Company’s variable rate debt equal to the notional amount of the derivative agreement.  The effect of the Company’s interest rate swap is to change a variable rate debt obligation to a fixed rate for that portion of the debt equal to the notional amount of the derivative agreement.  The interest rate derivatives are recorded at fair value with changes in fair value included in current period earnings within interest expense.  The fair value of the interest rate derivatives is based on a model whose inputs are not observable and therefore are categorized as a Level 3 input. The inputs in the valuation model include three-month LIBOR rates, unobservable adjustments to account for the SIFMA index, as well as any recent interest rate cap trades with similar terms.
	Assets and liabilities measured at fair value on a recurring basis are summarized below:

	Commitments and Contingencies
	The Company, from time to time, may be subject to various legal proceedings and claims that arise in the ordinary course of business. These matters are frequently covered by insurance. If it has been determined that a loss is probable, the estimated amount of the loss is accrued in the consolidated financial statements. While the resolution of these matters cannot be predicted with certainty, management believes the final outcome of such matters will not have a material effect on the Company’s consolidated financial statements.
	Certain of the MF Properties own apartment properties that generated LIHTCs for the previous partners in these partnerships.  In connection with the acquisition of partnership interests in these partnerships by subsidiaries of the Company, the Company has agreed to reimburse the prior partners for any liabilities they incur due to recapture of these tax credits to the extent the recapture liability is due to the operation of the properties in a manner inconsistent with the laws and regulations relating to such tax credits after the date of acquisition. No amount has been accrued for this contingent liability because management believes that the likelihood of any payments being required thereunder is remote.
	The Company provided a guarantee on the $2.8 million mortgage secured by the Abbington at Stones River, a 96 unit multifamily property located in Tennessee, in addition to providing the approximately $1.6 million taxable property loan to Foundation for Affordable Housing, the not-for-profit owner of the property. Based on the historical financial performance of the property and its estimated fair value, the Company estimates there is no value to record for this mortgage guarantee.
	In connection with the sale of the Greens Property, the Company entered into guarantee agreements with the BC Partners under which the Company has guaranteed certain obligations of the general partner of the Greens of Pine Glen limited partnership, including an obligation to repurchase the interests of the BC Partners if certain “repurchase events” occur. A repurchase event is defined as any one of a number of events mainly focused on the completion of the property rehabilitation, property rent stabilization, the delivery of LIHTCs, tax credit recapture and foreclosure. No amount has been accrued for this contingent liability because the likelihood of a repurchase event is remote. The maximum exposure to the Company at June 30, 2014, under the guarantee provision of the repurchase clause is approximately $1.3 million which represents 75% of the equity contributed by BC Partners to date.
	In connection with the Ohio Properties transaction in 2011, the Company entered into guarantee agreements with the BC Partners under which the Company has guaranteed certain obligations of the general partner of these limited partnerships, including an obligation to repurchase the interests of the BC Partners if certain “repurchase events” occur. A repurchase event is defined as any one of a number of events mainly focused on the completion of the property rehabilitation, property rent stabilization, the delivery of LIHTCs, tax credit recapture and foreclosure. Even if a repurchase event should occur, 25% of the BC equity would remain in the Ohio Properties and thus BC, a third party, would have sufficient equity in the Ohio Properties for the Company to recognize the sale discussed in Note 9. No amount has been accrued for this contingent liability because the likelihood of a repurchase event is remote. The maximum exposure to the Company at June 30, 2014, under the guarantee provision of the repurchase clause is approximately $4.9 million which represents 75% of the equity contributed by BC Partners.
	In March 2013, a wholly-owned subsidiary of the Company executed a 35-year ground lease with the University of Nebraska - Lincoln (“Lessor”) with an annual lease payment of $100. The leased property will have a mixed-use development consisting of a 1,605 stall parking garage and 475 bed student housing complex constructed on it. The Lessor will own the parking garage and the Company will own the student housing. The Company currently estimates the construction of the student housing will cost approximately $34.0 million and executed a guaranteed maximum price contract with the general contractor for the construction. The lease agreement has a stipulation that if the parking garage is not completed by August 1, 2014, the Company will pay damages of $6,000 per day of delayed completion to the Lessor. The Company’s construction contract with the general contractor also stipulates that the general contractor will pay the Company $6,000 per day of liquidated damages for each day subsequent to August 1, 2014 that the parking garage is not completed. Construction has commenced and is estimated to be completed before the August 1, 2014 deadline.
	In June 2013, the Partnership executed a Bond Purchase Commitment agreeing to purchase an $8.0 million new mortgage revenue bond and a $500,000 taxable bond both secured by a multifamily property under construction in Albuquerque, New Mexico. The mortgage revenue bond will have a stated annual interest rate of 6.0% per annum, the taxable bond will have a stated rate of 12.0% per annum, and bond proceeds must be used to pay off the third party construction loan. The Partnership accounts for the Bond Purchase Commitment as an available-for-sale security and, as such, records the change in estimated fair value of the Bond Purchase Commitment as an asset or liability with changes in such valuation recorded in other comprehensive income.  As of June 30, 2014, the Partnership has estimated the value of this Bond Purchase Commitment and recorded in other assets an asset of approximately $41,000.
	The Partnership has also executed a Guarantee Agreement with the construction lender for this Albuquerque project. The terms of the Guarantee Agreement require the Partnership to guarantee that all construction costs are paid when due and pay any remaining outstanding principal and unpaid interest on the construction loan on or before July 1, 2015. Construction is expected to be completed in the first quarter of 2015 when the Partnership anticipates purchasing the mortgage revenue bond and taxable bond. No amounts have been accrued for this Guarantee Agreement as the Partnership expects that the construction loan will be sufficient to pay all costs during the construction period and that the proceeds from the mortgage revenue bond, taxable bond, and third party equity contribution to be sufficient to pay off all outstanding principal and interest on the construction loan on or before July 1, 2015.
	As the holder of residual interests issued in connection with its TEBS and TOB bond financing arrangements, the Partnership is required to guarantee certain losses that can be incurred by the trusts created in connection with these financings. These guarantees may result from a downgrade in the investment rating of mortgage revenue bonds held by the trust or of the senior securities issued by the trust, a ratings downgrade of the liquidity provider for the trust, increases in short term interest rates beyond pre-set maximums, an inability to re-market the senior securities or an inability to obtain liquidity for the trust. In each of these cases, the trust will be collapsed. If the proceeds from the sale of the trust collateral are not sufficient to pay the principal amount of the senior securities with accrued interest and the other expenses of the trusts, the Partnership will be required to fund any such shortfall pursuant to its guarantee.

Subsequent Events [Text Block]	'
	Subsequent Events
	Mortgage Revenue Bond Purchase
	In August 2014, the Company acquired at par the approximate $18.1 million mortgage revenue bond secured by Bruton Apartments, a 264 unit multifamily apartment complex under construction in Dallas, Texas. The mortgage revenue bond carries an annual interest rate of 6.0% and matures on August 1, 2054.
	Forward Commitment
	On July 2, 2014, the Partnership entered into a Bond Purchase Commitment agreeing to purchase up to approximately $9.9 million new mortgage revenue bond secured by a multifamily property under construction in Vancouver, Washington. The mortgage revenue bond will have a stated annual interest rate of 6.25% and bond proceeds must be used to pay off the third party construction loan. The Partnership will account for the Bond Purchase Commitment as an available-for-sale security and, as such, will record any changes in estimated fair value of the Bond Purchase Commitment as an asset or liability with changes in such valuation recorded in other comprehensive income.
	2014 TEBS Financing
	On July 2, 2014, a separate transaction occurred as a preliminary transaction to achieve the closing of the 2014 TEBS financing. DB purchased the SPEARS which securitized four TOB Trust facilities for approximately $45.9 million and approximately $26.5 million in the related residual LIFERS. DB held the ten mortgage revenue bonds that collateralized this transaction, the Greens Property, Arbors at Hickory Ridge, Avistar on the Boulevard, Avistar at Chase Hill, Avistar at the Crest, Avistar on the Hills Apartments, Avistar at the Oaks Apartments, and Avistar in 09 Apartments, until the 2014 TEBS financing facility closed on July 10, 2014.
	On July 10, 2014, the Partnership and its newly created consolidated subsidiary, ATAX TEBS II, LLC (“the 2014 Sponsor”), entered into a number of agreements relating to a new long-term debt financing facility provided through the securitization of thirteen mortgage revenue bonds, with a par value of approximately $118.4 million, owned by the the 2014 Sponsor pursuant to the 2014 TEBS financing. The 2014 TEBS financing facility essentially provides the Partnership with a long-term variable-rate debt facility at interest rates reflecting prevailing short-term tax-exempt rates.
	Effective July 1, 2014, the Partnership transferred the following mortgage revenue bonds to the 2014 Sponsor pursuant to the 2014 TEBS financing described above:
		July 1, 2014
	Description of Mortgage Revenue Bonds	Bond Par Amount		Financial Statement Presentation
	Arbors at Hickory Ridge	$	11,450,000	Mortgage revenue bond
	Avistar at Chase Hill A Bond	10,000,000		Mortgage revenue bond
	Avistar at the Crest A Bond	9,700,000		Mortgage revenue bond
	Avistar at the Oaks A Bond	7,800,000		Mortgage revenue bond
	Avistar in 09 A Bond	6,735,000		Mortgage revenue bond
	Avistar on the Boulevard A Bond	16,525,000		Mortgage revenue bond
	Avistar on the Hills	5,389,000		Mortgage revenue bond
	Copper Gate Apartments	5,220,000		Mortgage revenue bond
	Greens Property A Bond	8,396,000		Mortgage revenue bond
	Harden Ranch A Bond	6,960,000		Mortgage revenue bond
	The Palms at Premier Park Apartments	20,152,000		Mortgage revenue bond
	Tyler Park Apartments A Bond	6,075,000		Mortgage revenue bond
	Westside Village A Bond	3,970,000		Mortgage revenue bond
	Total	$	118,372,000
	The mortgage revenue bonds were then securitized by transferring these assets to Freddie Mac in exchange for Class A and Class B Freddie Mac Multifamily Variable Rate Certificates (collectively, the “2014 TEBS Certificates”) issued by Freddie Mac. The 2014 TEBS Certificates represent beneficial interests in the securitized assets held by Freddie Mac. The Class A TEBS Certificates were issued in an initial principal amount of approximately $94.7 million and were sold through a placement agent to unaffiliated investors. The Class B 2014 TEBS Certificates were issued in an initial principal amount of approximately $23.7 million and were retained by the 2014 Sponsor. The gross proceeds from the 2014 TEBS financing were approximately $94.7 million. After the payment of transaction expenses, the Partnership received net proceeds from the 2014 TEBS financing of approximately $91.6 million. The Partnership applied approximately $72.4 million of these net proceeds to retire the short-term securitization that previously existed on these bonds and $6.3 million to a stabilization escrow.
	The holders of the Class A 2014 TEBS Certificates are entitled to receive regular payments of interest from Freddie Mac at a variable rate which resets periodically based on the weekly SIFMA floating index rate plus certain credit, facility, remarketing, and servicing fees (the “Facility Fees”). As of closing, the SIFMA rate was equal to 0.04% and the total Facility Fees were approximately 1.5%, resulting in a total initial cost of borrowing of approximately 1.5%. In order to mitigate its exposure to interest rate fluctuations on the variable rate 2014 TEBS financing, the 2014 Sponsor also entered into interest rate cap agreements with Barclays Bank PLC, the Royal Bank of Canada, and Sumitomo Mitsui Banking Corporation, each in an initial notional amount of approximately $31.6 million, which effectively limits the interest payable by the 2014 Sponsor on the Class A 2014 TEBS Certificates to a fixed rate of 3.0% per annum on the combined notional amounts of the interest rate cap agreements through August 15, 2019.
	Payment of interest on the Class A 2014 TEBS Certificates will be made from the interest payments received by Freddie Mac from the Bonds held by Freddie Mac on designated interest payment dates prior to any payments of interest on the Class B 2014 TEBS Certificates held by the 2014 Sponsor. As the holder of the Class B 2014 TEBS Certificates, the 2014 Sponsor is not entitled to receive interest payments on the Class B TEBS Certificates at any particular rate, but will be entitled to all payments of principal and interest on the Bonds held by Freddie Mac after payment of principal and interest due on the Class A 2014 TEBS Certificates and payment of all Facility Fees and associated expenses. Accordingly, the amount of interest paid to the 2014 Sponsor on the Class B 2014 TEBS Certificates is expected to vary over time, and could be eliminated altogether, due to fluctuations in the interest rate payable on the Class A 2014 TEBS Certificates, Facility Fees, expenses, and other factors.
	Freddie Mac has guaranteed payment of scheduled principal and interest payments on the Class A 2014 TEBS Certificates and also has guaranteed payment of the purchase price of any Class A 2014 TEBS Certificates that are tendered to Freddie Mac in accordance with their terms which cannot be remarketed to new holders within five business days.  The 2014 Sponsor is obligated to reimburse Freddie Mac for certain expenses, including any payments made by Freddie Mac under its guaranty. These obligations of the 2014 Sponsor are also guaranteed by the Partnership.  The Partnership also entered into various subordination agreements with Freddie Mac under which the Partnership has subordinated its rights and remedies with respect to the mortgage revenue and taxable bonds and mortgage loans made by it to the owners of properties securing certain of the Bonds to the rights of Freddie Mac as the holder of the Bonds.
	The term of the 2014 TEBS financing coincides with the terms of the assets securing the 2014 TEBS Certificates, except the 2014 Sponsor may elect to purchase all (but not less than all) of the Bonds from Freddie Mac on either July 15, 2019 or July 15, 2024.  The 2014 Sponsor also retains a right to require a Bond to be released from Freddie Mac in the event of a payment default on the Bond which remains uncured for two consecutive scheduled payment dates or 60 days, whichever is shorter, by paying Freddie Mac the unpaid principal and accrued interest on the Bond plus a yield maintenance payment.  In addition, the 2014 Sponsor has a limited right to substitute new bonds for existing Bonds held by Freddie Mac in certain circumstances. Should the Partnership not elect to terminate the TEBS Financing on these dates the full term of the 2014 TEBS Financing runs through the final principal payment date associated with the securitized bonds, or August 1, 2050.
	TOB Trust Financing
	In July 2014, the Partnership executed a new TOB Trust under its credit facility with DB securitizing the Live 929 Apartments mortgage revenue bond borrowing approximately $35.0 million. The TOB Trust facility has an approximate 4.4% per annum fixed interest rate and will mature in July 2019. Pursuant to the terms of this TOB trust the Partnership is required to reimburse DB for any shortfall realized on the contractual cash flows on the SPEARS.
	In July 2014, the Partnership executed a new TOB Trust under its credit facility with DB securitizing the Decatur-Angle mortgage revenue bond borrowing $21.9 million. The new TOB Trust facility will mature in October 2016. On the date of closing the total fixed TOB Trust facility interest rate will be approximately 4.3% per annum. This will replace the March 2014 TOB Trust which was securitized by the Decatur-Angle mortgage revenue bond (Note 10). Pursuant to the terms of this TOB trust the Partnership is required to reimburse DB for any shortfall realized on the contractual cash flows on the SPEARS.

Segment Reporting [Abstract]	'
Segment Reporting Disclosure [Text Block]	'
	Segment Reporting
	The Company consists of five reportable segments, Mortgage Revenue Bond Investments, MF Properties, Public Housing Capital Fund Trusts, MBS Investments, and Consolidated VIEs.  In addition to the five reportable segments, the Company also separately reports its consolidation and elimination information because it does not allocate certain items to the segments.
	Mortgage Revenue Bond Investments Segment
	The Mortgage Revenue Bond Investments segment consists of the Company’s portfolio of mortgage revenue bonds which have been issued to provide construction and/or permanent financing of multifamily residential apartments.  Such mortgage revenue bonds are held as long-term investments.  As of June 30, 2014, the Company held forty-one mortgage revenue bonds not associated with Consolidated VIEs and two mortgage revenue bonds associated with Consolidated VIEs which are bonds that are eliminated in consolidation on the Company’s financial statements. The multifamily apartment properties financed by the forty-three mortgage revenue bonds contain a total of 5,607 rental units. Three of the bonds’ properties are not operational and are under construction (Note 4).
	MF Properties Segment
	The MF Properties segment consists of indirect equity interests in multifamily apartment properties which are not currently financed by mortgage revenue bonds held by the Partnership but which the Partnership eventually intends to finance by such bonds through a restructuring.  In connection with any such restructuring, the Partnership will be required to dispose of any equity interest held in such MF Properties.  The Partnership’s interests in its current MF Properties are not currently classified as Assets held for sale because the Partnership is not actively marketing them for sale, there is no definitive purchase agreement in existence that, under current guidance, can be recognized as a sale of real estate assets and, therefore, no sale is expected in the next twelve months. During the time the Partnership holds an interest in an MF Property, any net rental income generated by the MF Properties in excess of debt service will be available for distribution to the Partnership in accordance with its interest in the MF Property.  Any such cash distribution will contribute to the Partnership’s CAD.  As of June 30, 2014, the Company consolidated the results of eight MF Properties containing a total of 1,582 rental units plus the student housing complex in Lincoln, Nebraska that is currently under construction (Note 7).
	Other Investments
	The Partnership Agreement authorizes the Company to make investments other than in mortgage revenue bonds provided that these other investments are rated in one of the four highest rating categories by a national securities rating agency and do not constitute more than 25% of the Company’s assets at the time of acquisition as required under the Agreement of Limited Partnership. In addition, the amount of other investments is limited based on the conditions to the exemption from registration under the Investment Company Act of 1940. The Company currently owns other investments, PHC Certificates and MBS, which are reported as two separate segments. The PHC Trusts segment consists of the assets, liabilities, and related income and expenses of the PHC Trusts. The Partnership consolidates the PHC Trusts due to ownership of the LIFERS issued by the three PHC Trusts, which hold custodial receipts evidencing loans made to a number of local public housing authorities. Principal and interest on these loans are payable by the respective public housing authorities out of annual appropriations to be made to the public housing authorities by the HUD. This investment was acquired in July 2012. The MBS segment consists of the assets, liabilities, and related income and expenses of the MBS TOB Trusts that the Company consolidated due to its ownership of the LIFERs issued by the MBS TOB Trusts. These MBS TOB Trusts are securitizations of state-issued mortgage-backed securities which are backed by residential mortgage loans. These investments were acquired during the fourth quarter of 2012 through the second quarter of 2013 (Note 6).
	The Consolidated VIE Segment
	The Consolidated VIE segment consists of multifamily apartment properties which are financed with mortgage revenue bonds held by the Partnership, the assets, liabilities and operating results of which are consolidated with those of the Partnership as a result of consolidation guidance.  The mortgage revenue bonds on these Consolidated VIE properties are eliminated from the Company’s financial statements as a result of such consolidation, however, such bonds are held as long-term investments by the Partnership which continues to be entitled to receive principal and interest payments on such bonds.  The Company does not actually own an equity position in the Consolidated VIEs or their underlying properties.  As of June 30, 2014, the Company consolidated two VIEs containing a total 410 units (Note 3).
	Management closely monitors and evaluates the financial reporting associated with and the operations of the Consolidated VIEs and the MF Properties and performs such evaluation separately from the other operations of the Partnership through interaction with the affiliated property management company which manages the multifamily apartment properties held by the Consolidated VIEs and the MF Properties.
	Management’s goals with respect to the properties constituting the Company’s Consolidated VIE and MF Properties reportable segments is to generate increasing amounts of net rental income from these properties that will allow them to (i) make all payments of base interest, and possibly pay contingent interest, on the properties included in the Mortgage Revenue Bond Investments segment and the Consolidated VIE segment, and (ii) distribute net rental income to the Partnership from the MF Properties segment until such properties can be refinanced with additional mortgage revenue bonds meeting the Partnership’s investment criteria.  In order to achieve these goals, management of these multifamily apartment properties is focused on: (i) maintaining high economic occupancy and increasing rental rates through effective leasing, reduced turnover rates and providing quality maintenance and services to maximize resident satisfaction; (ii) managing operating expenses and achieving cost reductions through operating efficiencies and economies of scale generally inherent in the management of a portfolio of multiple properties; and (iii) emphasizing regular programs of repairs, maintenance and property improvements to enhance the competitive advantage and value of its properties in their respective market areas.
	The following table details certain key financial information for the Company’s reportable segments for the three and six months ended June 30, 2014 and 2013:

Description of New Accounting Pronouncements Adopted and Not yet Adopted [Text Block]	'
	Recently Issued Accounting Pronouncements
	In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers (Topic 606). ASU 2014-09 supersedes the revenue recognition guidance in Topic 605, Revenue Recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in the exchange for those goods or services. This standard is effective for annual reporting periods beginning after December 15, 2016. The Partnership is still evaluating the impact of this pronouncement on the consolidated financial statements.
	In April 2014, the FASB issued ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU 2014-08 raises the threshold for disposals to qualify as discontinued operations. It also requires additional disclosures for discontinued operations and new disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation. The ASU is effective for fiscal years beginning after December 15, 2014, and interim periods within those years.  The Partnership is still evaluating the impact of this pronouncement on the consolidated financial statements.
