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 Massachusetts: 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 right. Dwelling coverage should equal the cost to rebuild your home from the foundation up at today's construction prices. Market value includes land, which does not burn. Your mortgage balance is a financing number unrelated to construction cost.
Massachusetts makes this error easy to commit in the expensive direction, because land is a very large share of price here - the statewide median home price is about $690,000, and in Boston, the near suburbs, and on the Islands the land fraction is enormous. Insure a house to $690,000 because that is what it sold for, and you may be buying a great deal of coverage you do not need. Insure to your loan balance instead and you are likely to be badly under-covered. The only number that matters is construction cost.
Rebuilding in Massachusetts runs roughly $275 per square foot - the midpoint of a published $200 to $350 band covering materials, labor, and general contractor overhead and profit, excluding land.
Note where those land relative to Section 2's thresholds. A 2,000 square foot Barnstable coastal home at $550,000 is under the $600,000 cliff; a 2,400 square foot one at $660,000 is over it, at 5% - $33,000 out of pocket.
A limitation worth stating rather than burying: Massachusetts shares its exact $200-$350 band with Connecticut and New York. That makes this a regional construction-cost band applied to Massachusetts rather than a Massachusetts-specific survey, and no Massachusetts building department or insurance regulator publishes a competing figure to check it against. Read it as a range. On that 2,000 square foot home, the band runs $400,000 to $700,000 - a $300,000 spread on the same house. Get an actual replacement-cost estimate from your carrier or an independent estimator rather than relying on any 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 on the 2,000 square foot example. Full replacement cost $550,000, so the 80% threshold is $440,000. Suppose you carry the $300,000 reference limit instead, and a storm does $100,000 of damage. Your limit is three times the loss, so it feels safe:
You are $32,800 to $37,800 short on a claim comfortably inside your policy limit, entirely because Coverage A was set too low.
This is also the answer to the temptation Section 2 raised. Setting your limit at $599,999 instead of $650,000 to stay under a deductible cliff saves you $18,000 on one named-storm claim and costs you a proportional reduction on every partial claim you ever file. It is not a good trade.
