Whether the dwelling coverage on your policy would actually rebuild your house — and what a shortfall costs you at claim time. Planning estimate only, not an appraisal.
Your renewal jumped and the carrier said 'rates went up.' Here is what is actually driving it, how to tell whether yours outran your state's, and the four levers that genuinely move the number.
Flood and earth movement are excluded from every standard homeowners policy — and the clause that excludes them is written so a wind-and-water loss can be denied entirely. Here is what is out, and what fills each gap.
Non-renewed, cancelled, or declined: read the notice correctly, stop force-placed insurance, fix the reason code on it, and get the house insured again in 30 days.
The exact sequence to run when your house is damaged — mitigation, documentation, the claim call script, the adjuster visit, reading the estimate, and every escalation step in order.

From Home Insurance in Montana: What It Costs and What Actually Covers You
The most consequential number on your policy is your Coverage A limit, and the most common way it goes wrong is setting it to your home's market value or your mortgage balance.
Neither is right. Dwelling coverage should equal the cost to rebuild your home from the foundation up at today's construction prices. Market value includes land, which does not burn. Your mortgage balance is a financing number with no relationship to construction cost.
This is the one state in this group where the coastal-style error applies.
Montana's median home price is $527,848 — remarkably high for a state with low construction costs, and driven by land values in the Gallatin, Flathead and Bitterroot valleys. Rebuilding a 2,000 square foot home runs roughly $440,000 at the state's midpoint construction cost.
Market value exceeds rebuild cost by about $88,000 at the state medians. In Kansas, Missouri and Kentucky the relationship runs the other way, and insuring to purchase price leaves you short. In Montana, insuring to market value likely means over-insuring — paying premium on land value that cannot burn.
But be careful applying that statewide. Montana's land-value spread is extreme. A home outside Bozeman or Whitefish may be 60% land by value; a comparable home in Glendive or Havre may be 10% land. The statewide relationship tells you nothing reliable about your specific property, which is exactly why you need a replacement-cost estimate rather than a rule of thumb.
There is also a Montana-specific reason to be careful about under-insuring despite the above: rural rebuild costs run above urban ones. Materials travel further, contractor availability is thin, and after a wildfire season local building capacity is consumed. A remote property can cost meaningfully more per square foot to rebuild than any state average implies.
Rebuilding in Montana runs roughly $220 per square foot — the midpoint of a published $160 to $280 band covering materials, labor, and general contractor overhead and profit, excluding land.
On a 2,000 square foot home:
Take the band seriously:
A $240,000 spread on the same house. A limitation worth stating rather than burying: this source publishes coarse regional cost bands, and Montana shares its exact $160-$280 range with Arizona, Colorado, Georgia, Iowa, Kansas, Nebraska, North Dakota and South Dakota. It is a regional Mountain/Plains band applied to Montana, not a Montana-specific survey. No Montana building department or insurance regulator publishes a competing figure to check it against.
Two other national construction-cost series put Montana at $162 and $160 per square foot — and unusually, they agree closely with each other. They are not averaged in here, because they measure a narrower quantity: both land near a $162 national average, which is the construction-cost figure that excludes general contractor overhead and profit. Your rebuild will include a general contractor's overhead and profit. The higher figure is the right one for insurance purposes.
Get an actual replacement-cost estimate for your specific home from your carrier or an independent estimator — and in Montana, make sure whoever produces it accounts for your access, your elevation, and how far materials have to travel.
Most homeowners policies contain a coinsurance provision requiring you to insure the dwelling to at least 80% of its full replacement cost. Fall below that and the insurer does not merely cap your payout at your limit — it reduces every partial claim proportionally.
Work it on the Montana example. Full replacement cost $440,000, so the 80% threshold is $352,000. Suppose you carry the $300,000 reference limit and a hailstorm does $100,000 of damage to roof, siding and windows:
You are roughly $17,800 short on a claim well inside your policy limit, entirely because Coverage A was set too low. Your limit was three times the size of the loss. Nothing exceeded your coverage. None of this is visible until you file.
