Rent by unit size
These are HUD Fair Market Rents, the payment standard for a Housing Choice Voucher (Section 8). They often differ from the $1,832 market median above, and that is expected: FMR is the 40th percentile of standard-quality units and counts gross rent, so it includes essential utilities such as electricity, water, gas, sewer, and trash. The market median is asking rent, which usually excludes utilities. HUD sets FMR once a year; market rent here updates monthly.
