Montana Mortgage Guide 2026

Buying a Home in Montana

Montana's housing market looks nothing like it did five years ago. The typical home value statewide sat near $468,000 as of early 2026, per Zillow — up roughly 66% over four years, according to the Montana Free Press. Bozeman's median has climbed past $665,000; Missoula hovers above $550,000; even Billings, historically the state's most affordable major market, crossed $400,000. Remote-work migration accounts for a large share of that appreciation, and it shows no sign of reversing.

What gives Montana some relief: property taxes stay relatively modest, there is no state real estate transfer tax, and first-time buyers have access to below-market financing through the Montana Board of Housing. Understanding all three pieces before you shop changes the math substantially.

Montana Property Taxes

The Tax Foundation pegs Montana's effective property tax rate on owner-occupied housing at 0.61% for 2026 — roughly 40% below the national average of around 1.0%, and among the lowest of any Mountain West state. That low effective rate partially reflects Montana's graduated statutory assessment system, which the legislature restructured starting in 2025.

Under the current framework, the taxable value of a primary residence is calculated at graduated rates before local mill levies are applied:

Local mill levies vary by county and school district. A 500-mill rate is a rough midpoint for illustration; your actual rate will differ. On a $470,000 home assessed at current rates, the annual property tax bill typically lands in the $2,800 – $3,400 range (estimate, based on statewide effective rate). That works out to roughly $235 – $285 per month added to your mortgage payment through escrow.

Closing Costs in Montana (No Transfer Tax)

Montana is one of roughly a dozen states that charges no real estate transfer tax. There is also no state sales tax. These two absences trim closing costs compared to states like Colorado (which levies a transfer tax) or Washington (with its graduated REET). What you will pay in Montana:

You still need to file a Realty Transfer Certificate with the county clerk when recording your deed, but this is an administrative document, not a tax. Sellers in Montana typically pay real estate commissions plus title-related fees, bringing their total outlay to 8% – 10% of sale price — but again, no transfer tax component.

First-Time Buyer & Down Payment Assistance Programs

The Montana Board of Housing (MBOH), housed within the Montana Department of Commerce, administers several programs for first-time buyers and those who haven't owned a primary residence in the past three years. Eligibility requires a minimum 620 credit score, completion of a homebuyer education course, and at least $1,000 of the buyer's own funds (which may be a gift in some cases). Income and purchase price limits apply and are updated periodically at housing.mt.gov.

Regular Bond Loan Program

The flagship program offers 30-year, fixed-rate mortgages at below-market interest rates. Loan volume is funded through the sale of tax-exempt mortgage revenue bonds, which is what allows the rate to sit below conventional market rates. First-time buyers with incomes below posted limits — which vary by county and household size — qualify for the reduced rate on purchases up to the program's purchase price ceiling.

Bond Advantage Down Payment Assistance

Paired with the Regular Bond Loan, this program provides up to 5% of the purchase price (capped at $15,000) as a second loan at 0% interest. No monthly payments are required on the second loan; it becomes due when you sell, refinance, or pay off the first mortgage. For a buyer putting 3.5% down on an FHA loan, Bond Advantage can cover that entire down payment and leave room for some closing costs.

MBOH Plus 0% Deferred Down Payment Assistance

This separate DPA product offers up to $8,000 as a 0% deferred loan, repayable at sale or refinance. It can be used with conventional, FHA, VA, or USDA loans — not just the Regular Bond Program — giving borrowers more flexibility on the first mortgage product.

80% Combined Program

Designed for borrowers who want to avoid FHA mortgage insurance, the 80% Combined Program structures the purchase as two loans: an 80% LTV first mortgage from MBOH and a 20% LTV second mortgage from a partnering nonprofit. With the combined LTV at 100%, buyers can purchase with minimal cash down while staying off FHA's insurance requirements. The second loan terms are set by the nonprofit partner.

Mortgage Credit Certificate (MCC)

Montana's MCC converts 20% of the annual mortgage interest you pay into a dollar-for-dollar federal income tax credit, up to $2,000 per year. Unlike a deduction, a credit directly reduces your tax liability. On a $400,000 loan at 7%, you'd pay roughly $27,900 in interest in year one — 20% of that is $5,580, capped at $2,000. That $2,000 annual credit stays with you for the life of the loan as long as the home remains your primary residence. The MCC can be combined with MBOH loan programs or used with a market-rate lender.

Sample Monthly Payment (Estimate)

The figures below are illustrative estimates — not quotes — based on a hypothetical buyer purchasing a $470,000 home (near the statewide average) with 10% down.

A few things can shift that number meaningfully. Montana homeowners insurance has risen sharply — Insurify data puts the statewide average annual premium near $2,400 as of late 2025, up about 18% in a single year, driven by wildfire exposure and hail risk. Nearly 29% of Montana properties carry high wildfire risk. Getting multiple insurance quotes before closing is not optional; it's essential. On the tax side, buyers using the Regular Bond Program often secure below-market rates that reduce the P&I line by $100 – $250 per month compared to a conventional loan at current market rates.
