A Fair Market Rent is HUD's annual estimate of the 40th percentile of gross rent paid by recent movers into a standard-quality unit, set separately for each metropolitan area and nonmetropolitan county, per the agency's FY2026 Fair Market Rent Methodology (HUD USER, updated July 2025). The figure sets payment standards for the Housing Choice Voucher program and rent ceilings for several other federal housing programs. This is information about how the calculation works, not investment or rent-setting advice.
For a small landlord weighing a unit near a voucher-heavy submarket, or an investor trying to read local rent data the way a housing agency does, the FMR is one of the few rent benchmarks published with a fixed, documented methodology and a fixed annual release date.
What Is a Fair Market Rent?
Fair Market Rent is HUD's estimate of the 40th percentile of gross rent — contract rent plus tenant-paid utilities — for standard-quality units among recent movers in a given area, according to the FY2026 methodology document (HUD USER, July 2025). Gross rent is the sum a tenant pays for shelter and utilities combined, not just the contract rent a landlord collects.
The 40th percentile means 40 percent of qualifying units rent at or below the published figure and 60 percent rent above it. HUD has used the 40th percentile since fiscal year 1995, when it lowered the standard from the 45th percentile as a program cost-saving measure, per the same methodology document.
What Are FMRs Actually Used For?
FMRs determine payment standard amounts for the Housing Choice Voucher program, set initial renewal rents for some expiring project-based Section 8 contracts, and establish rent ceilings for HOME Investment Partnerships and Emergency Solutions Grants funding, according to HUD USER's Fair Market Rents overview page. They also cap award amounts for Continuum of Care homelessness grants and set flat rents in public housing.
A landlord in a voucher jurisdiction who wants to know the maximum rent a housing authority will typically subsidize for a given unit size and county is, in effect, looking for the local FMR or its more granular counterpart, the Small Area FMR, calculated at the zip-code level for metro areas with wide rent variation, per HUD USER.
How Does HUD Calculate the Number?
The FY2026 calculation runs through several sequential adjustments, according to the FY2026 methodology document. It starts with five-year American Community Survey estimates of two-bedroom adjusted-standard-quality gross rent — for FY2026, the base data comes from the 2019–2023 ACS five-year file. Those figures must clear a quality bar: a margin of error under 50 percent of the estimate and at least 100 survey cases in the underlying sample.
From there, HUD applies a recent-mover adjustment, comparing one-year ACS rent estimates for movers to the five-year baseline through a hierarchical geographic fallback when local one-year data is too thin. The base rent is then inflated from 2023 dollars to 2024 dollars using a blend of private rental data — from six commercial providers including CoStar, Zillow, and RealPage — weighted at roughly 64.8 percent, and CPI-based shelter inflation weighted at roughly 35.2 percent, per the methodology document. A final trend factor forecasts the 2024 estimate forward to fiscal year 2026 dollars using one of several time-series models.
Two floors and a ceiling apply before a number is published. An FMR cannot fall below the lesser of the state's nonmetropolitan median or the national nonmetropolitan median — set at $973 for FY2026, according to the Federal Register notice published August 22, 2025. And no FMR is allowed to decline by more than 10 percent from the prior year, a limit HUD adopted in 2016 alongside its Small Area FMR rulemaking.
| Step | What Happens | Data Source |
|---|---|---|
| 1. Base rent | Five-year ACS two-bedroom gross rent estimate | 2019–2023 American Community Survey |
| 2. Recent-mover adjustment | One-year mover rents compared against the five-year baseline | ACS one-year estimates |
| 3. Inflation to base year | 2023 estimate inflated to 2024 dollars | Private rental data (~64.8%) plus CPI shelter inflation (~35.2%) |
| 4. Trend to fiscal year | 2024 estimate forecast forward to FY2026 | HUD time-series models |
| 5. Floors and caps | State/national nonmetro minimum applied; year-over-year decline capped at 10% | HUD FMR methodology rules |
What Changed in the FY2026 Methodology?
HUD made three documented changes for FY2026, per the methodology document. New construction is no longer excluded from the "adjusted standard quality" universe used in ACS and decennial census tabulations, following regulations tied to the Housing Opportunity Through Modernization Act. HUD also dropped a prior rule that treated units built within the last two years as automatically substandard for FMR purposes. And in Connecticut, HUD moved to current metropolitan statistical area definitions rather than the state's older town-based HUD Metro FMR Areas, reflecting Connecticut's own shift from towns to planning regions as its official geography.
For FY2026, the national FMRs took effect October 1, 2025, following publication in the Federal Register on August 22, 2025; that notice also opened a public comment and reevaluation-request period running through September 22, 2025.
How Does the Geography Work?
One FMR generally covers an entire metropolitan statistical area, spanning all its constituent counties, according to the methodology document. Nonmetropolitan counties each get their own FMR, except that Virginia's independent cities are grouped with an adjacent county. Six New England states — Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont — retain town-level FMRs for historical consistency. Where a metro county has enough independent survey data, HUD can also carve out a HUD Metro FMR Area, a subarea that captures local rent variation the metro-wide number would otherwise smooth over.
Why This Matters for a Small Landlord's Math
An FMR is not a market rent forecast and it does not tell a landlord what to charge on the open market; it is a program benchmark built from a three-year-old data lag by design — FY2026 figures rest on 2023 ACS data trended forward, per the methodology document. What it does offer is a documented, government-published number that a landlord evaluating a unit in a voucher-heavy area can compare against asking rents nearby, and a bedroom-size ratio structure — HUD applies bonuses of 8.7 percent for three-bedroom units and 7.7 percent for four-bedroom units relative to the two-bedroom base — that shows how HUD itself scales rent expectations by unit size. None of this is a substitute for local market data or professional advice on financing, tax, or legal questions specific to a property.
Frequently Asked Questions
Where can a landlord find the FMR for a specific county?
HUD USER publishes FMRs by state, county, and metropolitan area, including Small Area FMR lookups by zip code, on its public FMR dataset page, updated each fiscal year alongside the annual Federal Register notice.
Does a higher FMR mean market rents are rising?
Not necessarily. FMR reflects the 40th percentile of recent-mover rents from ACS data trended forward with CPI and private-data inputs, per the methodology document — it moves with underlying rent data but on a roughly three-year lag and through a specific formula, not a live market snapshot.
Can an FMR go down from one year to the next?
Yes, but only within limits. HUD caps any year-over-year decline at 10 percent of the prior year's figure, a floor adopted in 2016 alongside the Small Area FMR rule, according to the methodology document.
Is Fair Market Rent the same as Small Area FMR?
No. Standard FMRs apply metro-wide or county-wide; Small Area FMRs recalculate the same 40th-percentile standard at the zip-code level in metro areas with significant internal rent variation, per HUD USER's FMR overview page.
