- Unit: USD
- Definition: Monthly gross rent, in US dollars, that the U.S. Department of Housing and Urban Development (HUD) sets for a four-bedroom unit in the HUD area that contains the county. Gross rent is the rent plus all utilities paid by the tenant except telephone, cable or satellite television and internet. HUD sets Fair Market Rents at the 40th percentile of gross rents paid by recent movers for standard-quality rental units, from American Community Survey data brought forward to the fiscal year; until 2018 a few metropolitan areas were set at the 50th percentile. They set payment standards for Housing Choice Vouchers and rent ceilings in other HUD programs.
