Conforming limit vs FHA limit in St. Louis City
Two federal frameworks publish a limit for this county-equivalent, and they are not interchangeable. Conforming limits govern mortgages eligible for purchase by Fannie Mae and Freddie Mac. FHA limits govern mortgages FHA will insure.
| Program | One-unit limit | Authority |
|---|---|---|
| Conforming | $832,750 | FHFA · Fannie Mae and Freddie Mac |
| FHA | $541,287 | HUD · FHA-insured mortgages |
The two figures differ by $291,463 — a calculated difference, not a published one. The conforming figure is the larger of the two here. Neither limit governs the other program, and a larger limit is not a better mortgage — the two answer different questions.
