National Affordable Housing Management Association (Nahma)

Affordable housing is housing which is deemed affordable to those with a household income at or below the median, as rated by the national government or a local government by a recognized housing affordability index. Most of the literature on affordable housing refers to mortgages and a number of forms that exist along a continuum – from emergency homeless shelters, to transitional housing, to non-market rental (also known as social or subsidized housing), to formal and informal rental, indigenous housing, and ending with affordable home ownership. via Wikipedia ↗
