Home insurance is changing the cost of owning a house before some buyers even reach closing and before some current owners finish a renewal.
The U.S. Treasury Department found that homeowners insurance premiums rose 8.7% faster than inflation from 2018 to 2022. Consumers in the 20% of ZIP codes with the highest expected annual losses from climate-related perils paid an average premium of $2,321, which was 82% higher than the average in the lowest-risk ZIP codes.
Treasury also found that average nonrenewal rates in the highest-risk ZIP codes were about 80% higher than in the lowest-risk ZIP codes. A homeowner who gets a nonrenewal notice may have to find replacement coverage quickly, sometimes in a market where fewer insurers want the risk.
For buyers and current owners, the insurance check now belongs beside the mortgage rate, property tax estimate, roof age, flood risk, deductible, and rebuilding cost. A house can look affordable until the quote, renewal packet, or escrow notice arrives.
High-Risk ZIP Codes Are Paying More for Coverage
The Treasury data ranked ZIP codes by expected annual losses from climate-related perils, including severe storms, wildfire, flooding, and other hazards that can damage homes. The highest-risk areas paid substantially more for coverage between 2018 and 2022, and they also saw higher nonrenewal rates.
Those numbers can affect buyers before they make an offer. Two homes with similar list prices and mortgage estimates can carry very different insurance costs if one sits in an area with repeated storms, wildfire exposure, hail losses, flooding, older roofs, higher rebuilding costs, or insurer pullbacks.
Current owners face the same issue at renewal. A higher premium, changed deductible, reduced roof coverage, or nonrenewal notice can change the annual cost of keeping the property even when the mortgage rate itself has not moved.
Escrow Can Turn a Premium Increase Into a Higher Mortgage Payment
Home insurance does not sit outside the monthly housing budget for many borrowers. If the premium is paid through an escrow account, a higher insurance bill can raise the mortgage payment after the lender or servicer runs an escrow analysis.
The Consumer Financial Protection Bureau says monthly mortgage payments can change when homeowners insurance premiums or property taxes change inside an escrow account. A servicer may adjust the payment to cover the new insurance amount or an escrow shortage.
A fixed-rate mortgage can still come with a higher monthly payment when escrowed insurance or taxes rise. Homeowners who receive a renewal notice should compare the new premium with the amount currently being collected through escrow and watch for any shortage notice from the servicer.
Flood Damage Usually Needs a Separate Policy
A standard homeowners policy does not cover every major weather loss. FEMA says most homeowners insurance does not cover flood damage and that flood insurance is a separate policy.
That separate policy can matter in coastal areas, river communities, hurricane-exposed counties, flash-flood zones, and neighborhoods seeing heavier rainfall. A home can have wind coverage and still lack flood coverage if water enters from rising water, storm surge, or flooding that falls outside the homeowners policy.
Buyers should ask whether flood coverage is required before closing. Current owners should check whether flood coverage exists, what it covers, when it starts, and whether the lender or property location requires a separate policy.
Buyers Should Price Insurance Before Making an Offer
A listing price can look affordable before the insurance quote arrives. Roof age, prior claims, wildfire exposure, coastal location, hail history, distance from fire services, local rebuilding costs, and flood risk can all affect what a buyer is quoted.
Before making an offer, buyers should ask for early insurance estimates and find out whether separate flood coverage is needed. FEMA’s National Risk Index can help buyers review county-level exposure to natural hazards, but it should not replace an actual insurance quote for the property.
Current owners can run the same check before renewal by shopping early, asking whether deductibles changed, reviewing roof terms, checking replacement-cost limits, and confirming that the policy still covers enough to rebuild the house.
A Higher Premium Can Come With Less Protection
A higher bill does not always mean stronger coverage. Some homeowners may see larger deductibles, separate wind or hail deductibles, lower roof settlement terms, new exclusions, or other policy changes that leave more repair cost outside the claim.
Brookings notes that Treasury’s homeowners insurance data gives consumers and researchers a way to compare premiums, claims, and nonrenewals by ZIP code. That local data can help buyers and owners see whether insurance pressure is already showing up in the area around a property.
Before the old policy expires, homeowners should read the renewal packet for deductible changes, wind or hail language, roof coverage, replacement-cost limits, flood exclusions, nonrenewal notices, and any change that shifts more repair cost back onto the owner.
