Buying a home in Idaho

Idaho’s median home price of $420,000 puts it above the national median. At the current average rate of 6.95%, a buyer putting 15% down would pay $2,350/month in principal and interest — plus an estimated $221/month in property taxes, based on Idaho’s effective tax rate of 0.63%.

Choosing a 15-year loan in Idaho instead of a 30-year would save $273,420 in total interest, but increases your monthly P&I payment by $831. Whether that trade-off makes sense depends on your income stability, other financial goals, and how long you plan to stay in the home.

Idaho’s property tax rate of 0.63% is one of the lowest in the country. This means property taxes represent a moderate portion of your all-in monthly cost. First-time buyers often underestimate this line item — the calculator above includes it in the all-in monthly estimate so you see the true cost of ownership, not just the loan payment.
