The Federal Housing Finance Agency (FHFA) determines loan limits in Idaho and other states across the US. The FHFA is required to keep tabs on average home prices in the nation and to adjust the baseline conforming loan limit every year as needed to reflect changes in home prices.
In other words, if home prices increase by a certain amount in a certain county, the FHFA may boost the loan limits to keep up with increasing home values. Conforming limits are typically set at 115% of the average home price for each area, though they can go over this level in certain high-cost locations.
The 2026 conforming limit for most counties in Idaho is $832,750. The only exception to this baseline amount is Teton county. (See the table above for county-by-county details.)
Over the recent past, the FHFA has used home values estimated by the Federal Housing Administration (FHA), which is a part of HUD, so there are many federal housing agencies that have a hand in establishing loan limits.

Generally speaking, loan limits are increased to reflect an increase in home prices across the state and country. In order to accommodate higher home prices, conforming loan limits are increased. That said, loan limits aren’t automatically increased for every county. Some county loan limits may stay the same, while others may even be decreased.
According to FHFA’s recent news release:
“U.S. Federal Housing (FHFA) today announced the conforming loan limit values (CLLs) for mortgages Fannie Mae and Freddie Mac (the Enterprises) will acquire in 2026. In most of the United States, the 2026 CLL value for one-unit properties will be $832,750, an increase of $26,250 from 2025.“
As such, most Idaho and US counties are seeing higher conforming loan limits this year in comparison to 2025. Home prices across the nation increased by roughly 0.1% throughout 2025. In Idaho, home prices saw an increase in 2025 by 0.7%.
