The database details the four types of subsidies for rental units in New York City, including HUD Financing and Insurance, HUD Project-based Rental Assistance, the Mitchell-Lama program and Low-Income Housing Tax Credit (LIHTC) program. The database shows approximately 11,000 affordable-housing units which could possibly expire in the next few years without renewal because they are part of programs that no longer exist. The database is user-friendly, providing subsidy information to both policy makers and the public, especially New York tenants who reside in subsidized housing units.
