Montana Mortgage Calculator
This calculator pre-fills Montana's local figures — a median home price near $450,000 (7% pricier than the U.S. median), property tax at 0.74% of home value per year (below the national average, roughly $278/month here), and typical homeowners insurance of about $268/month — so the estimate reflects buying in Montana, not a generic national number. All told, a median-priced purchase with 20% down on a 30-year loan runs near $2,821/month before HOA dues or PMI. Adjust any input to match the home you're actually considering, and the tax and insurance lines recalculate with it.

Property taxes in Montana
Montana's effective property-tax rate is about 0.74% of a home's value each year — lower than the U.S. average of 1.1%. On the state's median home price of $450,000, that works out to roughly $3,330/year ($278/month) added to your payment.
Good to know: Montana has no statewide sales tax and reappraises property every two years — a sensitive issue lately, as Bozeman- and Missoula-area price surges have pushed reassessments sharply higher.

Homeowners insurance in Montana
Lenders require homeowners insurance, and in Montana it averages about $3,215/year ($268/month) for a policy with $300,000 in dwelling coverage — 26% above the U.S. average of $2,543. Premiums run high here, so it's worth comparing several insurers and asking about wind, hail or flood deductibles that may apply separately. The calculator above already includes this figure in the monthly estimate — replace it with a real quote when you have one.
Buying a home in Montana
A typical Montana purchase looks like this: the median home at $450,000 — 7% pricier than the $420,000 U.S. median — bought with 20% down on a 30-year loan near 6.5% costs about $2,275/month in principal and interest. Property tax adds $278/month at the state's 0.74% effective rate (below the national average), and average homeowners insurance another $268/month, for an all-in figure around $2,821/month — before HOA dues or PMI if your down payment is under 20%. The calculator above uses these local defaults, so adjusting the price or rate recalculates the whole picture for Montana.
