Quick answer
The median Montana home is worth $425,400, 5.6 times the state’s median household income, the 8th-highest ratio in the country. With 10% down at the 7.24% national average rate it costs about $3,219 a month, including property tax at 0.69% of value. Montana bars transfer taxes, and the Montana Board of Housing lends up to 5% of the price, capped at $15,000, for the down payment. After you buy, apply for the homestead reduced tax rate or the home is taxed at the full residential rate.

Montana’s price-to-income gap
Montana’s median home value of $425,400 ranks 17th among the states and DC, above the US median of $360,600. Its median household income of $75,340 ranks only 36th. Divide one by the other and Montana homes cost 5.6 times income — the 8th-highest ratio in the country, against 4.4 for the US.
That gap shapes everything below: at today’s rates, a median local income doesn’t stretch to a median local home without help, a second earner or a cheaper house.
The monthly cost of a median Montana home
$425,400 home, 10% down, 30-year fixed at 7.24%
| Part of the payment | Monthly |
|---|---|
| Principal and interest on $382,860 | $2,609 |
| Property tax at 0.69% | $245 |
| Homeowners insurance at the national $4.90 per $1,000 | $174 |
| PMI (midpoint of Freddie Mac’s range) | $191 |
| Total | $3,219 |
Property tax is the lighter part: Montana’s effective rate of 0.69% is below the national 0.89% and the 19th-lowest in the country. The weight is in principal and interest, because prices are high relative to pay. Adjust the inputs in the payment calculator.
Shopping at the price a Montana income supports
Freddie Mac suggests keeping housing under 30% of gross income. For the median Montana household that is $1,884 a month, which supports a home of about $249,000 with 10% down at today’s rate — $176,400 below the state median.
A first-time buyer at $249,000 with a low down payment and Board of Housing help
| Amount | |
|---|---|
| Down payment at 3.5% (the FHA minimum) | $8,715 |
| Closing costs at the low end of the CFPB range | $4,980 |
| Board of Housing assistance (5% of the price, up to $15,000) | $12,450 |
| Cash you bring (at least $1,000) | $1,245 |
The assistance turns a down payment and closing bill into a much smaller check, but it doesn’t lower the price your income supports. The affordability calculator shows that price at several debt-to-income limits.
Montana Board of Housing down payment loans
The Montana Board of Housing (MBOH), part of the Department of Commerce, offers two down payment and closing cost loans. Both require you to qualify first for an MBOH Regular Bond Program first mortgage through a participating lender, a credit score of at least 620 for every borrower, a cash investment of at least $1,000 (gifts allowed) and homebuyer education.
| Bond Advantage DPA | MBOH Plus | |
|---|---|---|
| Amount | Up to 5% of the price, max $15,000 | Up to 5% of the price, max $15,000 |
| Interest | Same fixed rate as the first mortgage | 0% |
| Repayment | 15-year amortizing loan | No payments; due when you sell, transfer, refinance or pay off the first loan |
| Income limit | Regular Bond Program limits | $80,000 for 1–2 people, $90,000 for 3 or more |
At the median price, the $15,000 cap is lower than 5% of the price, so the dollar cap is the limit that binds. On the median home, the full Bond Advantage amount would add about $137 a month for 15 years at a rate equal to today’s national average (the actual rate matches your MBOH first mortgage); MBOH Plus adds nothing monthly but has lower income limits. Compare both in the first-time buyer programs guide.
Apply for the homestead tax rate after you buy
Montana now taxes a principal residence at a reduced homestead rate — but only if you apply. Homes without it are taxed at the residential rate of 1.9% of market value (the share that local mill levies are applied to). To qualify, you must own the home as an individual or through a revocable trust and live in it at least 7 months of the year.
Move in
Close on the home and make it your principal residence.
Apply
File the Department of Revenue’s homestead application online or by mail. For 2026 the window ran from December 1, 2025, to March 1, 2026; check the department’s dates for the next tax year.
Stay current
Pay your property taxes on time; you must be current by the deadline for the application to be approved.
Reapply when you move
If you sell and buy another Montana home, file a new application for the new address.
A separate homestead declaration, filed with your county, protects home equity from unsecured creditors up to a limit set in state law — $350,000 in 2021, rising 4% each year since. It doesn’t change your tax bill.
No transfer tax, by constitution
Montana’s constitution bars both state and local governments from taxing the transfer of real property, so no transfer or deed tax appears on your closing statement — only recording fees. Closing costs on the median home, at the CFPB’s typical range, would run $8,508–$21,270. The closing cost calculator itemizes them.
