Montana Mortgage Calculator Guide
When I use a statewide mortgage page, I treat the first result as a reference point, not a promise. In Montana, the statewide home-value benchmark gives us a consistent place to begin, while the city pages show why the same down payment and interest rate can still produce different monthly totals. The current benchmark is $471,700, and this guide covers 36 city calculators. That sequence keeps the first estimate simple without hiding the local details that can change a real monthly payment.

Down-payment comparison
What 5%, 10%, and 20% down could look like in Montana
These examples use the $471,700 statewide benchmark, a 6.75% 30-year fixed planning rate, the 0.81% midpoint property-tax assumption, and 0.35% annually for homeowners insurance. PMI is illustrated at 1% annually below 20% down.
| Down payment | Cash down | Loan amount | Principal & interest | Property tax | Insurance & PMI | Estimated monthly payment |
|---|---|---|---|---|---|---|
| 5% | $23,585 | $448,115 | $2,906 | $320 | $531 | $3,757 |
| 10% | $47,170 | $424,530 | $2,753 | $320 | $531 | $3,605 |
| 20% | $94,340 | $377,360 | $2,448 | $320 | $138 | $2,905 |
The examples do not include HOA dues, closing costs, discount points, lender fees, flood insurance, or property-specific insurance adjustments. Change the city calculator inputs before using a result for a budget.
Local variation
Why one Montana estimate should not represent every city
The available city-page tax assumptions run from 0.42% for Red Lodge to 1.22% for Glendive, with a midpoint of 0.81% used in the statewide examples. That spread is a reminder to verify the parcel, assessment, exemptions, and taxing district before relying on a monthly number. Red Lodge and Laurel and Glendive are useful starting points for seeing how the planning assumptions vary inside Montana.
These are effective-rate planning assumptions from 2024 public data, published in this system in 2026. Actual tax bills depend on assessed value, exemptions, levies, and the property's taxing districts.
Cash-to-close research
Homebuyer assistance in Montana
The state-level research list currently contains 2 programs. Montana Housing Bond Advantage Down Payment Assistance and Montana NeighborWorks Down Payment Assistance Loan are included as a place to begin, not as a promise of approval. Funding, income limits, first-time-buyer definitions, participating lenders, and eligible locations can change, so I would confirm the current rules before counting assistance as cash available at closing.
Montana NeighborWorks Down Payment Assistance Loan
Provides loans of up to $25,000 to qualified buyers for down payment and closing costs. Income and location restrictions apply.

Common questions
Planning a mortgage in Montana
How much is an estimated mortgage payment in Montana?
Using the current $471,700 statewide home-value benchmark, 20% down, a 6.75% 30-year planning rate, the 0.81% midpoint property-tax assumption, and a 0.35% insurance assumption, the estimated monthly payment is $2,905. Actual property, loan, tax, and insurance details can differ.
Does the Montana mortgage estimate include property taxes?
Yes. The statewide examples use a 0.81% midpoint from the available city-page assumptions. A property-specific estimate should use the actual parcel, assessment, exemptions, and local taxing districts.
How much down payment should I compare in Montana?
The page compares 5%, 10%, and 20% down. A smaller down payment reduces upfront cash but can increase the loan balance and may add mortgage insurance. Program and loan requirements vary.
Where should I verify Montana homebuyer assistance?
Start with each linked official program source. Verify current funding, income limits, purchase-price limits, property rules, participating lenders, and first-time-buyer definitions before relying on assistance.
