Montana has transformed from a sleepy Big Sky market into one of the fastest-appreciating in the Mountain West, with a median home price of $523,000 that reflects the explosion of remote-worker demand in cities like Bozeman, Missoula, and Whitefish. Property taxes are relatively low at 0.84%, adding about $4,393 annually on a median-priced home โ a modest carrying cost by national standards. Montana stands out for one major financial advantage: no sales tax at all. That means no tax on building materials, appliances, or contractor services, which reduces the real cost of new construction and renovation. Closing costs average 1.5%, translating to roughly $7,845 upfront on a median purchase. First-time buyers should look at the MBOH Bond Advantage and MBOH Regular Bond programs from the Montana Board of Housing, both offering below-market rates with down payment assistance. A 10% down payment on a $523,000 home requires saving $52,300, a significant hurdle that the MBOH programs can partially offset. Competition is fierce in resort-adjacent markets, with cash buyers common. Use the mortgage calculator to model how Montana's rates and taxes stack up in your monthly payment.
How Mortgage Payments Work in Montana
A standard mortgage payment in Montana 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 รท 12), and n is the number of monthly payments. On a $523K home in Montana with a 10% down payment at 6.51% over 30 years, your principal and interest payment comes to approximately $2,978/monthโ not including property taxes or homeowner's insurance.
Montana's property tax rate of 0.84% adds roughly $366/month to your total housing cost on a $523K home. This rate is near the national average of ~1.1%.
