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 New Jersey: 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 or blow away. Your mortgage balance is a financing number with no relationship to construction cost.
New Jersey makes this confusing in a specific way, because here the two numbers happen to sit close together. Median home price is about $550,000; rebuild cost on a typical home, worked below, is about $522,000. That proximity is a coincidence of a high-cost construction market meeting high land values, and it does not mean market value is a safe proxy. In a high-land-value Shore town, market value overstates rebuild cost substantially; in an inland town with cheaper land and the same construction costs, it understates it.
Rebuilding in New Jersey runs roughly $290 per square foot — the midpoint of a published $215 to $370 band covering materials, labor, and general contractor overhead and profit, excluding land.
On an 1,800 square foot home:
That is $222,000 above the $300,000 reference tier the premium comparisons in Section 1 are quoted at. If you carry $300,000 because that is the number you saw in a rate comparison, the gap is not marginal.
The band matters:
New Jersey carries the third-highest construction cost band in the country, and its $215 floor ties California, Hawaii, and Alaska for the highest low-end figure of any state. Even the cheapest plausible New Jersey rebuild is above the $300,000 reference tier.
Two independent cross-checks put New Jersey lower — one at $225 per square foot, another at $184 — but both measure a narrower quantity that excludes general contractor overhead and profit, which a real rebuild does not get to exclude. Worth knowing about; not a reason to insure to the bottom.
No New Jersey building department or insurance regulator publishes a competing rebuild-cost survey, so get an actual replacement-cost estimate for your specific home from your carrier or an independent estimator rather than relying on a per-square-foot rule.
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 $522,000, so the 80% threshold is $417,600. 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 $29,000 to $34,000 short on a claim well inside your policy limit, entirely because Coverage A was set too low. None of it is visible until you file.
