Check insurability before you buy a house
Get address-specific quotes and an eligibility answer during your inspection period, before you are committed. What to check and what to do if insurers say no.
Ask for an address-specific quote and a plain answer on eligibility while your inspection or due-diligence period is still open. A house that no standard insurer will write, or that costs three times what the one next door does, is a different purchase than the listing suggests, and the contract is the last point at which you can walk away or reprice. Roof age, electrical and plumbing, the property's claims history, natural hazards and the state of the local market decide most outcomes.
Lenders require insurance, so a house you cannot insure is a house you may not be able to finance. That alone makes this the cheapest check you will do.
Why do this before the offer is final
After you are under contract, the insurance picture is the last unknown, and it is the one most likely to move. Premiums have risen in many markets, insurers have narrowed what they will write in storm- and fire-exposed areas, and each company's underwriting rules are different. Triple-I, the industry's information institute, puts it directly in its home buyer's guide: don't wait until the last minute, get estimates, and confirm the property qualifies before you commit. It also warns that in some areas private coverage may not be readily available.
The same facts also affect your loan. Insurance is part of your monthly housing payment, and a lender counts it when it calculates what you can afford. A premium that is twice what you assumed shrinks what you can borrow or what you can comfortably pay.
A step-by-step check
- Get the address and the facts. From the listing, the seller's disclosure and your inspector, collect the year built, roof type and age, electrical panel, wiring and plumbing materials, heating system, square footage and any additions or conversions.
- Ask for the seller's loss history. Triple-I suggests asking the current owner to obtain a loss history report on the home. The seller can order a C.L.U.E. report (LexisNexis) or an A-PLUS property report (ISO). Entries are tied to the address, so claims by earlier owners show up too. See CLUE reports: how claims history follows you and your house.
- Call an independent agent with the address. Many agents will quote a house you do not own yet. Ask not only for a price but for eligibility: is the house acceptable as is, what conditions would apply, and which carriers declined. See captive agents, independent agents and direct insurers.
- Get at least two sets of quotes. Compare the same coverage on the homeowners quote comparison worksheet: dwelling limit, deductibles (especially wind and hail), roof settlement terms and exclusions.
- Check the hazards separately. Flood, wildfire, hail, hurricane and earthquake each have their own coverage rules. See below.
- Put insurance dates into the contract schedule. Decide with your agent or attorney whether to ask for a clause that lets you cancel if you cannot get insurance on acceptable terms by a set date. Some contract forms have one and many don't by default.
- Re-confirm after the inspection report. Quotes depend on what you tell the insurer. Give the carrier the inspection findings, and update the quote if the facts change.
A quote is not a guarantee. Insurers often review a new policy in its first weeks, with drive-by or aerial checks, and the standard ISO homeowners form allows cancellation in the first 60 days for any reason with 10 days' notice, though many states restrict this. Answer every application question accurately so the policy you buy is the one you keep.
What to check and what raises a flag
| Item | How to check | What can go wrong |
|---|---|---|
| Roof | Inspection report, permit records, the seller's invoice | Many insurers decline or limit older roofs or require actual-cash-value roof terms; see roof age limits: when insurers won't cover an old roof |
| Electrical panel and wiring | Inspector; look for Federal Pacific or Zinsco panels, knob-and-tube or aluminum branch wiring | Some insurers decline until replaced; see Federal Pacific, Zinsco and other problem electrical panels |
| Plumbing | Inspector; supply and drain pipe material, water heater age | Polybutylene and some galvanized or cast-iron systems draw declines or higher prices; see polybutylene, galvanized and other pipes insurers dislike |
| Heating | Wood stoves, space heaters, old boilers | Fire risk; some require professional installation proof |
| Prior claims | Seller's C.L.U.E. or A-PLUS report | Repeated water or fire claims, or damage never properly repaired |
| Fuel storage | Inspector or seller | Triple-I notes that many insurers will not insure homes with an underground oil tank |
| Liability features | Walk-through | Pool without a fence, trampoline, aggressive-breed dogs, a home business |
| Fire protection | Ask the agent for the fire protection class | Rural addresses far from a hydrant or station may cost more or be ineligible |
| Hazard exposure | Flood maps, wildfire scores, local storm history | Surcharges, percentage deductibles or closed markets |
| Condition | Inspection, your own eyes | Deferred maintenance, roof ponding, rot, failing drainage |
Triple-I adds that a wind or hail claim that led to a new roof reads favorably, while water damage is worth tracing to its cause and to proof of proper repair.
The hazards that set the price
Flood. A standard homeowners policy excludes flood. Check the address on FEMA's flood map (Flood zones and FEMA flood maps explained); if it falls in a special flood hazard area and you use a federally regulated lender, you will have to buy flood insurance. Ask the seller for any elevation certificate and for the flood policy's premium history. Even outside a mapped zone, flood happens.
Wildfire. Insurers score the address and sometimes the neighborhood. Ask the agent what the carrier's score is and whether defensible space work would change the outcome. See wildfire risk scores and how insurers use them.
Hurricane and wind. Expect a separate percentage deductible in many coastal states and a possible requirement for opening protection or a wind mitigation report. See hurricane and named-storm deductibles explained.
Hail and storms. In hail states, ask about roof deductibles and payment schedules.
Earth movement and sinkholes. Earthquake, landslide and sinkhole coverage are separate questions to put to the agent.
A hypothetical comparison
Say you are choosing between two houses at the same price. Home A has a 6-year-old roof, a modern panel and sits outside a flood zone; the quotes you collect come to about $2,400 a year. Home B is similar, but the roof is 21 years old, the inspection found a Zinsco panel, and it sits in a mapped flood zone; the best quotes are $5,400 for homeowners coverage plus $1,800 for flood. These figures are invented to show the arithmetic, not market prices.
Home B costs $4,800 a year more to insure, or $400 a month, before repairs. If the seller agrees to replace the panel and give a credit toward the roof, the gap narrows. If neither happens, the extra $400 a month belongs in your offer, in your budget and in your lender's calculation. This is the real value of checking early: you get to put a number on it while you still have leverage.
If standard insurers say no
Being declined by the voluntary market is not the end, but the alternatives work differently, and each should be priced before you commit.
- State plans of last resort. FAIR plans and, in Florida, Citizens exist for properties that cannot get coverage elsewhere. Eligibility rules differ: in Florida, a new applicant is not eligible if an authorized insurer offers comparable coverage unless that premium is more than 20% above Citizens', under Fla. Stat. 627.351. The California FAIR Plan reported 696,562 policies in June 2026, per its published statistics. These policies are often narrower than an HO-3, so ask what is excluded. See FAIR plans explained: the insurer of last resort for homes, Florida and California.
- Surplus lines insurers. Non-admitted carriers can write risks standard carriers decline, with fewer consumer protections and, in most states, no state guaranty fund behind them. See surplus lines home insurance when standard carriers say no.
- A combination. A basic plan policy plus a difference-in-conditions policy to fill the gaps is common.
- Fix the cause and reapply. A new roof or panel can change the answer. Ask the seller to do the work before closing, or negotiate a credit and a post-closing deadline you can meet.
If no workable coverage exists at a price you can carry, the right move may be to walk away, which is far cheaper in the contract period than after closing. More options are in finding coverage for a hard-to-insure home and when your home seems uninsurable.
Key takeaways
- Ask for an address-specific quote and eligibility answer during your inspection period, while you can still renegotiate or cancel.
- Roof age, panels and plumbing, claims history, fuel tanks and natural hazards drive most declines and surcharges.
- Ask the seller for a C.L.U.E. or A-PLUS loss history report, and give the insurer the inspection findings.
- Put the insurance cost into your monthly budget and your offer; a $4,800 yearly gap is $400 a month.
- If standard carriers decline, price the FAIR plan, surplus lines or a combination before you decide, and consider asking for repairs or credits.
