Do Home Insurance Companies Share Data?
Yes. Insurers pull a report of your past home insurance claims, so your claims history follows you to a new policy.

The CLUE report
Insurers use a database called CLUE to pull up to seven years of claims tied to you and the house itself. A past owner's claims on that house can show up too, even if you never filed one.
Effect on your price
Prior water damage or a liability claim at the address can raise what you're quoted, even before you've owned the place a day. Ask the seller about past claims early. A surprise quote right before closing is hard to fix fast.
Your lender's deadline
The lender needs proof of coverage before funding the loan, a binder showing the policy will take effect at closing. A flagged claims history can slow an insurer's underwriting, so starting the application early matters.
Checking the report yourself
You can request your own CLUE report to see what insurers see before you apply. If something on it looks wrong, you can dispute it, but that takes time you may not have right before closing.
Since the house's claims history can raise your quote before you've signed anything, it's worth seeing what another insurer would charge for the same place. One company's underwriting might weigh a past water damage claim more heavily than another's, and that difference can show up fast. Comparing quotes now, while there's still time before the lender's deadline, keeps you from being stuck with the first number you got.
What else insurers check besides your claims history
CLUE is not the only file an insurer pulls. Most also check your credit-based insurance score, which is a separate thing from your regular credit score and is calculated just for this purpose. Some states limit or ban the use of credit in setting home insurance rates, so whether this applies to you depends on where the house is. Where it's allowed, a thin or troubled credit history can push your quote up the same way a past water damage claim does.
The house itself gets looked at apart from any claims tied to it. Insurers want to know the age of the roof, the type of wiring and plumbing, and whether the home has had updates to any of those systems. An older roof nearing the end of its expected life can raise a quote or even cause an insurer to decline to write the policy until it's replaced. This is worth asking the seller about alongside past claims, since both affect the number you'll see.
Public records about the property can factor in too, including permits pulled for past work and, in some areas, wildfire or flood risk scores tied to the address rather than to any person. None of this is secret. An insurer has to tell you what information it used if it denies coverage or charges you more because of it, and you can ask what went into a quote before you accept it.
Because so much of this is tied to the house rather than to you personally, two different buyers of the same home would likely see similar quotes from the same insurer, but quotes can still vary widely between companies. One insurer might weigh an aging roof heavily while another focuses more on the claims history. Getting a few quotes before the lender's deadline is the only way to see which approach works in your favor, and it costs nothing to check while there's still time.
What if the insurer charges more because of a report?
An insurer that charges you more or turns you down because of something in your report has to tell you. This is called an adverse action notice. It names which report was used, like CLUE or a credit-based insurance score, and gives you a way to get a free copy of it. If a quote comes back higher than expected, that notice is where to look for why, rather than guessing.
The notice won't always spell out exactly which claim or which part of your credit history mattered most. It points you to the reporting company, and from there you can request the full file yourself. For CLUE, that means contacting the company that runs it. For a credit-based score, the insurer can usually tell you which bureau supplied the data behind it. Either way, you're entitled to see the actual report, not just the insurer's summary of it.
If you spot an error, like a claim listed that was never filed, or one that was closed with no payout but shows as open, you can dispute it with the company that holds the file. Disputes typically take a few weeks to resolve. That's longer than most closing timelines allow. This is the main argument for pulling your own CLUE report and checking your credit standing as soon as the house is under contract, well before any insurer runs its own check.
None of this means the number you're quoted is final or fixed. Since the adverse action notice names the specific report that drove the price, you'll know whether it was the house's claims history, your own credit file, or something else. That's useful information when shopping other insurers, since one company's underwriting might lean harder on credit while another cares more about the claims tied to the address. Knowing which factor is driving your quote tells you which other quotes are worth getting before the lender's deadline arrives.
Before you lock in a policy
Pull your own CLUE report and ask the seller about past claims now, while there's still time to fix a surprise before the lender's deadline. Then see what a few insurers quote for the same house.
