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 Ohio: What It Costs and What Actually Covers You
The most consequential number on your policy is your Coverage A limit, and in Ohio it is also the number most likely to be wrong — by a lot.
The common error is setting Coverage A 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.
Ohio demonstrates this more starkly than almost any state in this dataset, because the two numbers are far apart and point the wrong way.
Rebuild cost is roughly 1.7 times market value. Land is inexpensive across most of Ohio; construction is not, and construction costs are set by national materials markets and regional labor rather than by local home prices.
If you insure an Ohio home to what it would sell for, you are dramatically underinsured. This is the single most common and most consequential mistake on Ohio policies, and it is made by people who thought they were being careful.
Rebuilding in Ohio runs roughly $235 per square foot — the midpoint of a published $170 to $300 band covering materials, labor, and general contractor overhead and profit, excluding land.
On an 1,800 square foot home:
That is $123,000 above the $300,000 reference tier the premium comparisons in Section 1 use, and $177,500 above the state's median home price.
The band:
An honest caveat about this figure. Ohio shares its exact $170-$300 range with Missouri, which makes it a regional construction-cost band applied to Ohio rather than an Ohio-specific survey. Read it as a range, not a point.
Two independent cross-checks put Ohio construction at $160 and $159 per square foot — both close to the national middle, and both materially below the figure used here. Both measure a narrower quantity that excludes general contractor overhead and profit, which a real rebuild does not get to exclude. They are worth knowing about and they are not a reason to insure at $160 per square foot.
No Ohio building department or insurance regulator publishes a competing rebuild-cost figure, so get an actual replacement-cost estimate for your specific home from your carrier or an independent estimator.
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. Full replacement cost $423,000, so the 80% threshold is $338,400. Suppose you carry the $300,000 reference limit and a storm does $100,000 of damage. Your limit is three times the loss, so it feels safe:
You are $12,000 to $14,000 short on a claim well inside your policy limit, purely because Coverage A was set too low.
Now consider the homeowner who insured to market value — $245,500 on a home costing $423,000 to rebuild:
And on a total loss there is no proration to argue about at all: the policy pays its limit, and the $177,500 gap between $245,500 and $423,000 is entirely yours.
