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 Idaho: 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 correct. Dwelling coverage should equal the cost to rebuild your home from the foundation up at today's construction prices. Market value includes land, and land does not burn. Your mortgage balance is a financing number with no relationship to construction cost.
In Idaho this error usually runs in the direction of overinsuring. Idaho's median home price is about $503,400 — high for an interior state, driven by the Boise metro — and a substantial share of that is lot value. If you set Coverage A to your purchase price, you are likely paying premium on land that cannot be destroyed.
Rebuilding in Idaho runs roughly $215 per square foot — the midpoint of a published $170 to $260 band covering materials, labor, and general contractor overhead and profit, excluding land.
On a 2,000 square foot home:
Take the band seriously rather than the midpoint alone:
That is a $180,000 spread on the same house. It is a wide band, and it is honest to say why: this is a coarse published cost band rather than an Idaho-specific survey, and no Idaho building department or insurance regulator publishes a competing rebuild-cost figure to check it against. It should be read as a range, not a number.
Note also what this figure is not. It is construction cost — materials, labor and contractor overhead to rebuild finished living area after a loss. It is not market value, and it is not the price per square foot of a home sale. Treating one as the other is the single most common way a replacement-cost estimate goes wrong.
Now compare the two Idaho numbers side by side. Median home price $503,400. Rebuild cost for a 2,000 square foot home $430,000. For a typical Boise-area home the land is a meaningful fraction of the price, and the gap widens the closer you get to expensive lots. Get an actual replacement-cost estimate for your specific home from your carrier or an independent estimator rather than working from either number.
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 threshold and the insurer does not simply cap your payout at your limit — it reduces every partial claim proportionally.
Work it on the example. Full replacement cost $430,000, so the 80% threshold is $344,000. Suppose you carry the $300,000 reference limit instead, and a fire does $100,000 of damage. Your limit is three times the loss, so it feels perfectly safe. It is not:
You are roughly $13,800 short on a claim well inside your policy limit, entirely because Coverage A was set too low. None of that is visible until you file.
