HUD Fair Market Rent or the GSA Lodging Rate: Which Should You Budget From?
Neither one is your rent: HUD’s Fair Market Rent estimates what ordinary unfurnished apartments in an area rent for by the month, while GSA’s lodging rate is the nightly ceiling on a tax-free lodging allowance. Treat the Fair Market Rent as a reference for long-lease rents nearby, the GSA rate as the cap on what a tax-free lodging stipend can be, and a real listing near the facility as your budget.
What does HUD's Fair Market Rent measure?
HUD defines Fair Market Rents as “estimates of 40th percentile gross rents for standard quality units within a metropolitan area or nonmetropolitan county.” Its methodology adds that these rents “include both shelter costs and tenant-paid utilities.”
Read that as three limits. It is a monthly figure for an ordinary lease. It is for an unfurnished unit. And it sits below the middle of the market, at the 40th percentile. A furnished place on a short lease is a different product, which is why each city guide here notes that the figure is not a furnished or short-term price.
What does the GSA lodging rate measure?
GSA sets per diem rates “that federal agencies use to reimburse their employees for lodging and meals and incidental expenses incurred while on official travel within the continental United States.” The lodging part is a maximum per night, set by location, and in some areas it changes by month. For federal fiscal year 2027 GSA publishes a standard rate for most of the continental states and higher rates for listed areas; GSA rates by state lists every one.
For a traveler the rate matters because of an IRS rule in Publication 463: “If your allowance is less than or equal to the federal rate, the allowance won’t be included in box 1 of your Form W-2.” That makes the GSA rate a ceiling on the stipend an agency can pay that way, not a promise of what any agency pays.
How do you compare a monthly rent with a nightly rate?
Put them in the same unit first. The Fair Market Rent is per month and GSA’s lodging rate is per night, so multiply the nightly figure by the nights in the month you are pricing before you set them side by side.
Charlotte shows how far apart they sit. The Charlotte guide sets GSA’s fiscal year 2027 lodging rate for Mecklenburg County beside HUD’s fiscal year 2027 Fair Market Rent for a one-bedroom in the Charlotte area, and the monthly rent comes out well below a month of nights at the GSA rate. Every city guide on this site shows both numbers, rendered from the HUD and GSA files, so you can make the same comparison for any contract city. The two numbers answer different questions: GSA’s is set for federal employees on official travel, HUD’s describes rents on ordinary leased units. Your housing usually sits between them, furnished, on a short lease, for about the length of a contract.
If you want an offer whose housing stipend you can check against these figures, ask a ProTherapy recruiter: Find my next contract.
Which number should set your housing budget?
Neither on its own. Use them as bounds and let a listing decide:
- Your stipend is the number on your package. The GSA rate caps how much of it can be paid under the IRS rule above, and an agency is free to quote less.
- The Fair Market Rent tells you what an ordinary unfurnished lease in the area costs, utilities included. A furnished listing priced near it is worth a close look; one far above it is charging for furniture, flexibility or location.
- A listing near the facility is the only figure that is actually your rent. Price furnished options on the lease length you need, then run them through the housing worksheet for a weekly margin.
What does this comparison not tell you?
Whether the stipend is untaxed for you. That turns on your tax home and on Publication 463 rules that the stipend decision guide walks through, without applying them to your situation. It also leaves out deposits, partial months and a contract that ends early; the housing options comparison covers those terms.
Both figures change each federal fiscal year, and GSA’s can change by month. Look up the county where the facility is on GSA’s site and the area on HUD’s before you sign, not from a figure you saw last year.
Frequently asked questions
Is HUD's Fair Market Rent what I will pay for a furnished rental?
No. HUD's figure estimates 40th percentile gross rents for standard quality units, including tenant-paid utilities, on ordinary leases. It is not a furnished or short-term price, so use it as a reference, not a quote.
Can my housing stipend be more than the GSA lodging rate?
The IRS rule that keeps an allowance out of box 1 of your Form W-2 covers an allowance less than or equal to the federal rate, which GSA publishes for each location. Ask a tax professional how any amount above that rate would be treated before you rely on it.
Where do I find the GSA lodging rate for my assignment?
On GSA's per diem rates page. Look up the location of the facility, because rates are set by location and some change by month.
