Housing market snapshot: Montana

Montana's desirable mountain and recreation towns have seen sharp price growth, while agricultural communities remain more affordable. Inventory can be thin outside Billings, Missoula, and Bozeman. An indicative median near $450,000 places Montana in a higher-cost cohort. Down payment size and PMI (or MIP) choices often matter as much as the note rate.

Property taxes and homestead notes

Montana's average effective property tax rate of roughly 0.74% is near the middle of the U.S. range. The dollar amount still scales with purchase price, so escrow on a median-priced home is material. Property taxes are moderate but have drawn attention amid rising values. Residential property tax relief programs may apply - check current DOR guidance.

Homeowners insurance in Montana

Indicative average homeowners insurance around $1,600/year is in a typical U.S. band. Roof age, claims history, and deductibles still swing real quotes. Wildfire risk is a major underwriting factor in forested areas. Winter access and older cabins can complicate coverage.

Worked payment example

Using Montana's indicative median of $450,000, a 20% down payment of $90,000, a 6.75% rate, and local tax/insurance defaults, principal and interest is about $2,335 with a full monthly payment near $2,746 (including roughly $278 tax and $133 insurance). With only 5% down ($22,500), the same price point jumps to about $3,380 per month because the loan is larger and PMI is typically required — roughly $196 of that total.

A common comfort check is keeping total housing cost near 28% of gross income. At $2,746/month, that implies ballpark gross income around $117,677 per year before other debts. Run your real income and debts through our home affordability calculator rather than relying on this rule of thumb alone.
