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 York: What It Costs and What Actually Covers You
Almost every underinsurance problem starts with the same mistake: insuring the home for what it is worth, or for what is owed on it, instead of what it costs to rebuild.
Your dwelling limit should be the cost to rebuild your home from the foundation up, at today's construction prices, on the lot you already own. It has nothing to do with your mortgage balance — the bank's interest and your rebuilding cost are unrelated numbers. And it has nothing to do with market value, because market value includes land, and land does not burn down.
The rebuild-cost figure this site uses for New York is $275 per square foot, the midpoint of a published $200-$350 band. That is construction cost: materials, labor, and general contractor overhead and profit to rebuild finished living area. It excludes land.
For a 2,000-square-foot New York home:
Compare that to New York's statewide median home price of $480,000 and the problem becomes obvious. The midpoint rebuild estimate for a mid-sized home is higher than the statewide median sale price. Insuring to market value would leave that homeowner roughly $70,000 short — and that is before considering that in much of upstate New York, market value sits well below rebuild cost, while in New York City and its suburbs the land component pushes market value far above it. There is no consistent relationship between the two numbers in either direction.
Two honest caveats on the $275 figure. First, it comes from a coarse regional cost band that New York shares with Connecticut and Massachusetts, so it is a Northeast construction-cost band applied to New York rather than a New York-specific survey. Second, the statewide figure is badly lossy: New York City and its suburbs sit well above it and much of upstate sits well below, and no sub-state breakdown is published. Use the band, get a real replacement-cost estimate from your carrier or an independent estimator, and treat $275 as the starting point rather than the answer.
Here is the mechanism that turns "a bit underinsured" into a bad day.
Most homeowners policies contain a coinsurance provision, commonly set at 80%. It says: to receive full replacement-cost settlement on a partial loss, you must carry dwelling coverage of at least 80% of your home's full replacement cost. Fall below that line and your partial-loss payments get reduced proportionally — not just on the shortfall, but on the entire claim.
Work it through on that 2,000-square-foot New York home with a $550,000 replacement cost:
Scale that to a total loss and it is worse: you carried $400,000 against a $550,000 rebuild, so you are $150,000 short of a finished house.
The fix is boring and effective: get your replacement cost re-estimated every few years, and after any significant renovation. Ask your carrier whether your policy includes extended replacement cost (typically an extra 10-50% above your dwelling limit if rebuilding costs spike) and inflation guard (an automatic annual bump to your limit). Both are cheap relative to what they protect against, and both address the specific failure mode where construction costs rise faster than your policy limit does.
