True Cost of Owning a Home in Montana (2026): Beyond the Mortgage
Your lender shows you one number. Here are all six — pre-loaded with Montana's real data.
The statewide median home price in Montana sits at $448,600, up -2.8% over the past year. That number gets quoted constantly, but it's the wrong number to plan around. What actually matters is the full monthly cost of ownership — and in Montana, that number is consistently 53% higher than the mortgage payment alone.
Most lenders pre-approve buyers for a payment that covers principal and interest — roughly $2,242/mo on a $448,600 home at current rates. What they don't model is the $254/mo in monthly property taxes at Montana's 0.68% effective rate, the $162/mo in homeowners insurance ($601 below the national average, which actually works in your favor), or the $561/mo per month that should go into a maintenance reserve. Add it all up and the true monthly cost reaches $3,422/mo.
Property taxes in Montana range from 0.42% in Treasure County to 0.88% in Silver Bow County (Butte). On the same $400,000 home, that's a difference of $1,840 per year — over $153 a month. That's not a rounding error. It's a budget line that changes whether or not a house is affordable, and it's the kind of thing that should be in every buyer conversation long before the offer stage.

Roof
Lifespan: 25-30 years (dry climate; snow load a concern in mountain areas; minimal humidity extends lifespan) · Replacement cost: $6,729–$15,701
wildfire defensible space maintenance is an ongoing annual cost in fire-prone areas
Water Heater
Lifespan: 8–12 years · Replacement cost: $1,200–$3,500 installed
Hard water and high-usage households shorten lifespan
Windows
Lifespan: 20–25 years · Replacement cost: $400–$1,000 per window installed
