Mortgage Calculator in Idaho

Calculate your monthly mortgage payment in Idaho using the 2026 median home price of $485K and current local rates. Adjust the inputs below. Formula shown, sources cited — no account required.

Few western states have seen home prices climb as sharply over the past decade as this one. The median price of $485,000 reflects strong demand from out-of-state buyers, remote workers, and retirees drawn by wide-open spaces and no state sales tax on groceries. Property taxes sit at 0.69%, which on the median home translates to roughly $3,347 per year — moderate by national standards and well below neighbors like Utah or Oregon. A typical buyer here puts 10% down, bringing $48,500 to closing plus another 1.3% in closing costs, or about $6,305. First-time buyers should look closely at the IFA First Loan program, which offers below-market interest rates and down-payment assistance paired with homebuyer education. Competition remains stiff in the Treasure Valley and around Coeur d'Alene, where inventory rarely satisfies demand. Getting pre-approved before you search is essential, and knowing your exact maximum monthly payment protects you from overextending. Use the mortgage calculator to stress-test your budget at different rate and price scenarios.
