HUD Fair Market Rents target the 40th-percentile gross rent in each metro area and are updated annually. For ZIPs in our sample dataset, you'll see a "high" confidence score (75-90). For ZIPs outside the sample, we fall back to a national median and clearly flag the result as extrapolated. For bedroom counts above 4, we extrapolate using HUD's historical incremental pattern (+18% per additional bedroom).
For a deal-level pricing decision, always combine this estimate with comparable listings on Zillow, Apartments.com, or your local MLS.
