Why a seller cares

If the home sits in a flood, fire or earthquake zone you know about, the disclosure says so, and in some states a report is ordered to say it for you. A flood zone in particular changes the buyer's insurance and their loan.

A simple example

Your home is in a mapped flood zone and carries a flood policy. The buyer's lender will ask for one too, and the disclosure tells them before the lender does.

The hazard disclosure tells the buyer what their insurer is about to tell them.

What people get wrong

That hazard zones are the buyer's job to research. Where the seller knows, the seller says, and some states require a formal report.
