What these limits mean for buyers in Bonneville County
The 2026 conforming 1-unit limit for Bonneville County is $832,750. Loans at or below this amount can be sold by the originating lender to Fannie Mae or Freddie Mac, which keeps pricing tight and underwriting consistent. Bonneville County uses the standard national conforming baseline.
For FHA financing, the 2026 1-unit limit is $541,287. The HUD CHUMS table pegs the median sales price for Bonneville County at $410,000. This matches the FHA national floor — Bonneville County did not qualify for an upward adjustment for 2026.
Practical takeaway. The median sales price in Bonneville County ($410,000) is below both limits — FHA, conventional, and VA financing all cover median-priced purchases here. Choice between programs comes down to credit, down payment, and overlay differences.
How the limits are set
Conforming limits come from the Federal Housing Finance Agency (FHFA), which adjusts them each year based on changes in the FHFA Housing Price Index. FHA limits come from HUD: the national floor is $541,287 (65% of conforming baseline), the ceiling is $1,249,125 (150% of conforming baseline), and counties between are calculated as 115% of the area median sales price.
Multi-unit and house-hacking math
Bonneville County 2-, 3-, and 4-unit conforming limits are $1,066,250, $1,288,800, and $1,601,750 respectively. If you're house-hacking — owner-occupying one unit of a 2-4 unit property — these are the limits that matter, and the rental income on the other units can be used to qualify. FHA and VA both finance owner-occupied 2-4 unit properties at their own multi-unit limits.
