Mortgage Association (GNMA). After GNMA assumed the mortgage, City Line ran into financial difficulties. Despite entering into a series of workout agreements with GNMA to adjust the mortgage and bring its loan payments up to date, City Line defaulted on the loan and GNMA assigned its rights to the mortgage to the insurer HUD. HUD then assumed the mortgage and became the lender. After several additional workout agreements between HUD and City Line, and an influx of additional capital from new partner Brunswick Management Company and the existing partners of City Line, the project stabilized and the mortgage arrears were eliminated.
Between 1988 and 1996, Congress enacted various statutes related to preservation of low-income multi-family housing built during the 1960s-1970s that were insured with these forty-year government-insured mortgage loansAct restored prepayment rights to City Line and other owners that had not entered into use agreements (which City Line did not). As of April 29, 1996, City Line was again allowed to prepay its mortgage and exit the program, though the statute prevented it from raising the rents for an additional two months after it prepaid (restricted until at least June 26, 1996). City Line filed suit at the Court of Federal Claims in November 1996, seeking damages for breach of contract or, alternatively, for just compensation under the Fifth Amendment for a regulatory taking. On August 13, 1997, City Line prepaid the mortgage on its housing project, thereby exiting the program.
