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 Iowa: What It Costs and What Actually Covers You
Dwelling coverage should equal the cost to rebuild your home from the foundation up at today's construction prices. Not market value, which includes land — land does not blow away. Not your mortgage balance, which is a financing number with no relationship to construction cost.
In Iowa the gap between those things is enormous.
Rebuilding in Iowa 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:
Iowa's median home price is $250,000.
It costs roughly $190,000 more to rebuild a typical Iowa home than to buy one — one of the largest such gaps in this series, comparable to Indiana's and larger than Arkansas's.
The mechanism is straightforward. Iowa has inexpensive land and ordinary Midwest construction costs. When land is nearly free, the market price of a house is close to what the structure alone is worth — and then five years of post-derecho construction cost inflation ran straight past it. The result is a state where the intuitive answer ("insure it for what I paid") is wrong by nearly $200,000.
A total loss pays your limit. That is the whole calculation.
In a state whose defining insurance event was a windstorm that destroyed housing at scale, this is the scenario to plan around.
Most homeowners policies also 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. Full replacement cost $440,000, so the 80% threshold is $352,000. Suppose you insured to market value — $250,000 — and a hailstorm does $100,000 of damage:
Over $31,000 short on a claim well inside your policy limit, entirely because Coverage A was set to what the house would sell for. None of it is visible until you file.
The $160-to-$280 range means the same 2,000 square foot house rebuilds for anywhere from $320,000 to $560,000. Iowa shares that exact band with eight other states — Arizona, Colorado, Georgia, Kansas, Montana, Nebraska, North Dakota, and South Dakota — which tells you plainly it is a regional construction-cost band applied to Iowa rather than an Iowa-specific survey. One independent cross-check puts Iowa at the top of that nine-state group. No Iowa building department or insurance regulator publishes a competing figure to arbitrate.
