Flood Insurance vs. Homeowners Insurance in 2026: What MLOs Must Know About SFIP and NFIP

Flood damage is one of the most common causes of residential property loss and one of the most frequently misunderstood insurance gaps. Standard homeowners insurance policies exclude flood damage by definition. When a property is in a Special Flood Hazard Area, lenders are legally required to mandate flood insurance under the Flood Disaster Protection Act. Missing this requirement can kill a closing or create significant post-closing liability.

When Flood Insurance Is Required

Flood insurance is federally mandated on any federally backed mortgage where the property is in a FEMA-designated Special Flood Hazard Area, which includes Zones A and V. The lender must order a flood zone determination at or before closing. If the determination confirms SFHA designation, flood insurance must be in place before funding. The coverage must be at least equal to the lesser of the outstanding principal balance or the maximum coverage available under NFIP.

NFIP vs. Private Flood Insurance

• ✦NFIP covers up to $250,000 for the structure and $100,000 for contents; for properties with replacement costs above $250,000 an excess flood policy is needed
• ✦Private flood insurance has been acceptable for Fannie Mae loans since 2019 if it meets the minimum coverage requirements; it often provides higher coverage limits and broader terms
• ✦Freddie Mac also accepts private flood insurance meeting its requirements; the policy must be from an insurer rated A- or better by AM Best
• ✦FHA accepts private flood insurance for HECM and single-family programs when the policy meets HUD requirements
• ✦Private flood premiums are sometimes lower than NFIP for newer construction and properties in moderate-risk zones; always compare both

Flood Zone Changes and Letter of Map Amendment

Properties can be removed from SFHA designation through a FEMA Letter of Map Amendment or Letter of Map Revision. If a borrower believes their property is incorrectly mapped in a flood zone, they can petition FEMA. If successful, flood insurance is no longer required. For MLOs with clients in contested flood zones, this process can save significant annual premium costs and is worth flagging.
