The Tenant Interim Lease (TIL) program provides renters that live in City-owned buildings the opportunity to own those units as a cooperative. Existing tenants of buildings that participate in the program are required to attend building management education programs, and rents are restructured to enable the property to be converted to cooperative ownership with maintenance fees sufficient to cover ongoing operating expenses. After the building achieves stable occupancy rates and operating expenses, all units in the property are transferred from New York City’s Department of Housing Preservation and Development (HPD) to tenants as cooperatives for $250 an apartment (TIL tenants who agreed to participate in the later Affordable Neighborhood Cooperative Program faced a new price of $2,500). HPD initially funded the rehabilitation of these buildings using a modest scope and later included gut rehabilitation.
