Mortgage rates in Idaho
Average 30-year fixed 6.49% · Updated July 9, 2026 · Freddie Mac (FRED)
Boise was one of the decade’s fastest-appreciating metros. Below is what buying at Idaho's median price looks like at today's national average rate, plus the local property tax and assistance that actually change your payment.
What a mortgage costs in Idaho
The interest rate on a Idaho mortgage is the same 6.49% national average a lender would quote anywhere — rates are set by the bond market, not by your state. On Idaho's median $599,900 home with 20% down, the financed amount is $479,920, or about $3,030 a month in principal and interest.
What makes Idaho different is the cost around the loan. Its 0.63% effective property-tax rate adds roughly $315 a month, and homeowners insurance about $225 more — bringing the all-in estimate to $3,570. Those local costs, not the interest rate, are what set Idaho apart. Your own price and down payment will move the number — work backward from your income with the affordability check.

Down-payment help in Idaho
You rarely need 20% down. Idaho Housing — Idaho's housing finance agency — runs the state's main assistance program: Idaho Housing offers down-payment and closing-cost assistance up to 7%. Eligibility usually turns on income limits and a homebuyer-education course. Check current terms at Idaho Housing, see how a smaller down payment changes your number with the minimum down payment tool, or compare first-time buyer help by state.
