What it isn't
This report summarizes public data so you know what to ask. It is not a home inspection, appraisal, survey or official flood zone determination, and hazard ratings describe the surrounding area rather than the specific house.
Lenders use an official Standard Flood Hazard Determination for insurance requirements.
