Buying a home in Montana
Lenders qualify Montana buyers on gross income, but the budget that actually pays the mortgage is net of state income tax that reaches 5.90% at the top — a few percentage points of headroom that a pre-approval letter quietly assumes you have. Property tax adds a second, permanent layer at roughly 0.74% of assessed value per year.
A buyer earning $100,000 with $600 monthly recurring debt, 20% down, and a 6.5% 30-year fixed mortgage can typically afford a home up to about $391,178.75 in Montana, with an estimated monthly housing cost around $2,333.33. The 2026 median single-family home price in Montana is around $560,000.
The 0.74% property tax used here is a statewide effective average — actual bills are set at the county and city level and can differ substantially within Montana. Verify with Montana Department of Revenue (https://mtrevenue.gov/taxes/montana-tax-tables-and-deductions/) and the county assessor before setting a price ceiling.

What is the property tax rate in Montana?
Montana's effective property tax rate is approximately 0.74% of assessed home value annually. That is close to the US national median. On a $560,000 home, expect roughly $4,144 per year in property tax.
What is the median home price in Montana?
The 2026 median single-family home price in Montana is around $560,000. With 20% down that means a down payment near $112,000 and a financed amount of about $448,000. Prices vary widely by metro — coastal and urban areas typically exceed the state median by 30%–60%.
Is Montana good for first-time homebuyers?
Montana state income tax reduces take-home pay, which lenders factor into debt-to-income ratios. Property tax at 0.74% is in line with the national average. Montana first-time buyers may qualify for state-administered down-payment-assistance programs through the state housing finance agency.
What's the 28/36 rule and how does it apply in Montana?
Lenders typically cap front-end DTI (housing payment / gross monthly income) at 28% and back-end DTI (housing + all debt / gross monthly income) at 36%. In high-property-tax states like Montana (~0.74% property tax), the front-end ratio binds sooner because property tax and insurance can push monthly housing 25%–35% above pure principal & interest. Use the comfortable, stretch, and maximum ranges above to gauge how aggressive your budget is.
Can I afford more house in Montana or South Dakota?
On the same $100,000 income, 20% down, 6.5% rate, good credit profile, the estimated max home price is $391,178.75 in Montana vs $369,010.84 in South Dakota. Montana allows about $22,167.91 more purchasing power — driven mainly by differences in state income tax (affecting take-home) and property tax rates.
