Why Are Home Insurance Companies Allowed to Use Credit Scores?
States allow it because insurers' data shows credit-based scores predict claim risk, though a few states ban the practice entirely.

For someone buying a house, this mostly matters because the quote tied to your application may already reflect your credit. If your score is strong, you likely won't notice. If it's thin or still recovering, ask the insurer how much weight it carries in your state, since some cap the effect and a handful, like California and Massachusetts, don't allow it at all. Either way, the lender only cares that the dwelling coverage and binder are in place by closing, not what shaped the price.
Your Credit Isn't the Only Factor Insurers Weigh
Credit history is one piece of the quote. The rest comes from dwelling coverage, deductible and how each insurer prices the same house. Comparing quotes shows whether your credit is costing you more than it should.
What Insurers Actually Look At in Your Credit
Insurers don't pull your FICO score. They use something called a credit-based insurance score, built from the same credit bureau data but weighted differently. Payment history matters, but so does the length of your credit history, how much available credit you're using, and whether you have a mix of account types. A medical bill in collections or a missed payment from two years ago can carry more or less weight than it does for a loan application, because the formula is built around claims data, not lending risk.
Someone with a decent FICO score can still land in a weaker tier for insurance purposes. The models insurers use look for patterns that showed up repeatedly in people who filed claims, and some of those patterns don't line up with what a mortgage lender cares about. If you're buying your first house and have thin credit, meaning a short history or few open accounts, that alone can place you in a less favorable tier even with no missed payments at all.
Insurers are required to disclose when your premium reflects a credit-based score, and that notice typically comes with the quote or the policy documents. If you want to see the number itself, you can ask the insurer directly, and several states require them to tell you. What you can't do is fix it before closing. Credit-based insurance scores update periodically as your credit file changes, so paying down a card or correcting an error on your credit report now may help at your next renewal, not this quote.
A few things do not factor in anywhere in this calculation. Your income, your employment, and your address's ZIP code demographics are not part of it. Race is barred from use as well. If a quote looks high and you suspect credit is the reason, ask the company what score range it used and whether an error on your credit report might be pulling it down. Disputing a mistake with the credit bureau can take a few weeks to resolve, so it's worth checking your credit report early if closing is approaching fast.
Can You Improve Your Score Before Closing?
Probably not in time to change this quote. Credit-based insurance scores are usually pulled once when you apply. They don't refresh mid-underwriting just because you paid off a balance. If closing is a few weeks out, anything you do to your credit now matters for the next renewal, not this policy.
Checking your credit report is still worth doing. Errors are common, and they're the one thing that can sometimes be fixed fast enough to matter. Pull your report from all three bureaus before you apply for coverage, not after. If you find an account that isn't yours, a balance reported wrong, or a collection that should have aged off, dispute it right away. Bureaus generally have 30 days to investigate, which is tight against a closing date but not impossible if you start as soon as you're under contract.
If a correction comes through before your policy is issued, tell the insurer and ask if they'll re-pull your credit before binding coverage. Some will, especially if the change is significant and you ask directly. Many won't rerun it automatically, so this only happens if you raise it yourself. It costs nothing to try.
For most first-time buyers, the more useful move is getting quotes from a few insurers instead of one. Credit weighting isn't the only variable, and it isn't weighted the same way by every company. One insurer's model might penalize a thin credit file more than another's does. Comparing quotes side by side shows whether a high price is about credit or just about how that insurer prices the house, the coverage amount, or the deductible you chose. The binder your lender needs can still be in place on time either way. Fixing the score is a longer project that starts now and pays off at renewal, not before closing.
Before You Lock In a Quote
Pull your credit report from all three bureaus now and dispute anything wrong. Then get quotes from a few insurers, since credit weighting differs by company and the gap might come from somewhere else entirely.
