What these numbers are, and are not
Everything above is computed from the FFIEC's HMDA Modified Loan/Application Register, the public loan-level file nearly every mortgage lender must submit each year, filtered to originated, first-lien, owner-occupied principal-residence loans that were not business-purpose or reverse mortgages. Groups smaller than 5 loans are omitted. The methodology page documents every step.
The public file contains no credit scores, so differences between lenders mix true pricing differences with different customer bases: loan sizes, points paid, and borrower profiles all vary by lender. A median is context for your own quote, not a ranking and not an offer. Rates here are also a year's worth of closings blended together, while your quote reflects a single day's market.

Common questions
What mortgage rate did people get in Custer County in 2025?
The median interest rate on closed home-purchase loans in Custer County, Idaho in 2025 was 6.5%, across 36 first-lien, owner-occupied loans. The middle half of borrowers got between 6.125% and 6.875%.
Is this a rate I can get today?
No. These are medians of loans that already closed, under those borrowers' credit profiles, loan sizes, discount points, and lock dates. Rates also move daily. The way to learn your own number is to collect Loan Estimates from two or three lenders, which federal rules make close to free.
Why do lenders in the table show different rates?
Partly pricing, partly customer mix. Public HMDA data contains no credit scores, so a lender serving stronger-credit borrowers or larger loans will show a different median than one serving first-time buyers, at identical pricing. Use the table as a map of who is active locally and roughly where they land, not as a ranking.
Where do these numbers come from?
The FFIEC's public HMDA Modified Loan/Application Register, the loan-level data nearly every mortgage lender must file each year, filtered to originated, first-lien, owner-occupied, non-business, non-reverse loans, in groups of at least 5.
