How Loan Limits Are Established

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. This is exactly what happened from 2018 to 2019. 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 2020 conforming limit for most counties in Idaho will be $510,400. The four exceptions to this baseline amount are Blaine, Camas, Lincoln, Teton counties. (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.

Why Loan Limits Increased for 2020

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 November 2019 news release:

“As a result of generally rising home values, the increase in the baseline loan limit, and the increase in the ceiling loan limit, the maximum conforming loan limit will be higher in 2020 in all but 47 counties or county equivalents in the U.S.”

As such, most Idaho and US counties will see higher conforming loan limits next year in comparison to 2019. Home prices across the nation have increased by roughly 4% throughout 2019. In Idaho, home prices saw great appreciation in 2019, with the median home value of $275,100 an increase of over 11% as of December 2019, compared to the same time last year. This is why we are seeing higher conforming loan limits in Idaho for 2020.
