The NAHMA Affordable 100 comprises the largest affordable multifamily property management companies, ranked by affordable unit counts. The NAHMA Affordable 100 list contributes vital data to the ongoing national dialogue on the future of federal funding for affordable housing. In an effort to accurately determine the portfolio of affordable units receiving federal subsidy in the United States, NAHMA publishes this annual listing of affordable units containing at least one of the following federal subsidies: HUD Project-based Assistance, Section 42 LIHTC, HOME funds, USDA Section 515, or Bonds.

NAHMA also presents two specialty lists – the 25 largest housing credit (LIHTC) property management companies, and the 25 largest Rural Development program property management companies.
