There's a report on you, and on your house
It's called a CLUE report, run by LexisNexis. It generally holds up to seven years of home and auto claims, and carriers check it when you apply or ask for a quote. Insurers can report a claim they paid, a claim they denied, and even one they only opened a file on.
