Buying a Home in a Flood Zone: What to Know

Due Diligence Before You Buy

Before making an offer on a property in a flood zone, research the property's flood history thoroughly. Request the seller's flood insurance claims history, which is available through FEMA's National Flood Insurance Program. Properties that have received multiple claims may be classified as Severe Repetitive Loss properties, which can affect future insurability and costs.

Order a flood zone determination from a certified company to confirm exactly which zone the property is in. Cross-reference this with the current FEMA flood map and check whether map updates are pending that could change the designation.

Understanding the True Cost

Calculate the total annual cost of owning the property, including flood insurance premiums. In high-risk zones, premiums can range from $1,500 to over $10,000 annually depending on the property's elevation relative to the BFE, construction type, and coverage amount.

Request an elevation certificate if one does not exist. This $300-$600 investment tells you the property's exact flood risk and what your insurance premium will be. Without it, you are buying blind on one of the largest ongoing costs of ownership.

Negotiation Leverage

Flood zone designation is a legitimate negotiation factor. Properties in high-risk zones should be priced lower to reflect the ongoing cost of insurance and the risk of damage. Use comparable sales data from both inside and outside flood zones to support your negotiation position.

Ask the seller about any mitigation improvements such as elevation, flood vents, or improved drainage. These improvements reduce your future costs and indicate the property has been thoughtfully managed.

Mortgage and Financing Considerations

Lenders for properties in SFHAs will require proof of flood insurance before closing. Some lenders may have stricter requirements than the federal minimum, potentially requiring higher coverage amounts or specific deductible levels. Factor insurance costs into your pre-approval calculations. Use our ZIP code tool to research flood zones before you start house hunting in a new area.
