Buying in Idaho: what the numbers look like
Idaho keeps the recurring cost of ownership low: its 0.47% average effective property tax rate ranks 5th lowest in the nation (national average ≈ 0.94%), so the typical $445,000 home carries only about $2,092 a year in property tax. On the insurance side, Idaho homeowners average about $1,700 a year — a bargain at 37% below the 50-state average.
Put together at an illustrative 6.5% rate (30-year, 20% down), the typical Idaho purchase pencils out near $2,566/month: $2,250 principal & interest + $174 tax + $142 insurance. That's the number the calculator above starts from — swap in your real price, rate quote, and county figures to make it yours.
