How Mortgage Payments Work in Idaho
A standard mortgage payment in Idaho is calculated using the amortization formula:M = P[r(1+r)^n] / [(1+r)^n - 1]
Where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly payments. On a $415K home in Idaho with a 10% down payment at 6.87% over 30 years, your principal and interest payment comes to approximately $2,452/month— not including property taxes or homeowner's insurance.
Idaho's property tax rate of 0.69% adds roughly $239/month to your total housing cost on a $415K home. This rate is below the national average of ~1.1%, which helps keep total housing costs lower.
