HUD's official Fair Market Rent data as clean CSVs, two fiscal years in one pack. The FY2026 file set holds 51,895 ZIP-level rows across 3,229 counties and 52 states; the FY2027 update adds 51,871 rows with rates effective October 1, 2026. Every row carries monthly rents for 0-4BR units, metro or nonmetro flag, area name and state, with Small Area FMRs set at ZIP level in many metros. Each year also ships a county rollup (median and max FMR per county) and a state summary with median 2BR rents. A data dictionary explains every column, HUD's 40th-percentile gross-rent methodology and the source file hashes. Join the ZIP key to addresses, tenant records or listings to set rents, screen tenants, build rent comparators or anchor yield models to an official benchmark instead of scraped numbers. Public domain US federal data, no scraping, no estimates beyond what HUD published.
