 As a homeowner, there are several key ones you need to understand, starting with a CLU report. It's a record of every insurance claim filed on your home in the last seven years, and it could make selling your house a little more challenging if there have been persistent problems. The next is the WALK score, which indicates how walkable your neighborhood is. That's important because surveys show that a majority of younger homebuyers prefer communities where they can get out and walk. And one more score to pay attention to is the flood insurance rating. The risk of flooding where you live can affect whether you can get insurance or even a mortgage.
