Just because a property isn't in a known flood zone doesn't mean it's safe. Increasingly, flooding occurs in areas that never used to flood. Homeowners insurance is mandatory if you're in a FEMA flood zone, but standard policies often exclude flood damage—you'll need separate flood insurance that costs $500–$1,000+ per year. Check flood maps, ask neighbors about past water damage, and talk to your insurance agent before committing to a property in a risky area.
