Your claims history follows your house. Here is how to read it.

A CLUE report is your claims history report: the record of property claims tied to you and to your home that insurers check before they quote you. CLUE stands for Comprehensive Loss Underwriting Exchange, the database LexisNexis runs.

When an insurer opens or pays a property claim, it reports the basics to a shared industry database. That includes the address, the date, what kind of loss it was, and what was paid.

Other insurers can pull that history when they are asked to quote the property. It is a consumer report, in the same legal family as a credit report, produced by companies that operate under federal consumer-reporting law.

Two histories are being looked up, not one. There is a history attached to you personally, and a history attached to the property itself. That is why claims filed by the people who owned your home before you can appear on a report about your home.

Property loss history usually reaches back about seven years. Most insurers weigh the last five years much more heavily, and many base their rules entirely around that window. So an older claim counts for less each year, and eventually it drops off.

Casa does not order this report. The insurers that quote your home may, under the consumer report permission you check before the search runs.

Insurers are not just counting claims. They are reading a pattern. How often matters more than how much: two modest claims in three years usually hurt you more than one large claim from six years back.

An open claim that has not been repaired and closed out is its own problem. Nobody wants to take on a home with a known, unrepaired loss.

Water is the type of claim homeowners underestimate most. A burst supply line, a failed water heater, or a slow leak behind a wall reads to an insurer as a repeat problem.

It can carry far more weight than the dollar amount suggests, more than a one-time weather loss would. Two water claims on one property is among the most common reasons a standard insurer turns a home down.

This is worth knowing before you file a small claim. A claim you could pay for yourself can sit on the report for years, and cost you more, in higher prices and fewer choices, than it ever paid out.

Ask the company that keeps it. LexisNexis Risk Solutions runs the CLUE database, and Verisk runs a similar one called A-PLUS. Each gives you one free copy of your own file every 12 months.

Federal law also lets you request it again after an insurer uses a report against you. There is no reason to wait for an insurer to tell you what is in it.

Request it before you shop, not after. If something on it is wrong, a correction takes time to work through, and you would rather fix it while your quotes are still ahead of you. If you are in a non-renewal window, or in the middle of buying a home, order it the same week you start.

The practical route: ask the agent or company that quoted you which reporting company's report they pulled, then request your file from that company directly. They publish request instructions and a consumer phone line. Have your address history handy, because the file is looked up by property as well as by name.

Mistakes on these reports are common enough that checking is worth the effort, and most of them fall into a short list.

None of this is exotic. It comes from ordinary reporting slips in busy claims departments, and it is fixable once you can point at it.

• An inquiry recorded as a claim: you called to ask if something would be covered, never filed, and it shows up as a loss anyway.
• A claim from the prior owner. It happened at your address, on someone else's watch, and it is being read as your history.
• A duplicate. The same loss appears twice, sometimes with slightly different dates or amounts, which doubles your apparent claim count.
• A wrong amount. An early estimate or a reserve figure got reported instead of what was actually paid.
• A wrong loss type. Water coded as flood, or a weather loss coded as a maintenance failure, which changes how every insurer reads it.
• A claim that closed with no payment, but still shows as if it paid. A withdrawn claim that was never removed counts the same way.
• The wrong property. A neighboring address, a unit number typo, or an old address of yours attached to this house.

Dispute it in writing with the reporting company that produced the file. Say which entry is wrong, say why, and attach proof: the claim's closing letter, a repair invoice, or your home's closing documents if the loss predates your ownership.

The company generally has thirty days to investigate, and must tell you the outcome. An entry that cannot be verified comes off.

Push at the source too. Ask the insurer that reported the entry to correct what it sent, because a correction at the source is what keeps the entry from reappearing later.

Then request a fresh copy of the file and keep it, so you can hand a clean version to whoever is quoting you.

Set expectations honestly. An accurate claim does not come off just because it is inconvenient, and no dispute changes that.

A dispute fixes a record that is wrong. Time fixes a record that is right: as claims age past five years, then past seven, they carry less and less weight.

In the meantime, document the repair on any accurate claim, so the insurer can see the problem was actually fixed.
