Why is my lender requiring the purchase of flood insurance?

Lenders are mandated under the Flood Disaster Protection Act of 1973 and the National Flood Insurance Reform Act of 1994 to require the purchase of flood insurance by property owners who acquire loans from federally regulated, supervised, or insured financial institutions for the acquisition or improvement of land, facilities, or structures located within or to be located within an SFHA. The lender reviews the current NFIP maps for the community in which the property is located to determine its location relative to the published SFHA and completes the Standard Flood Hazard Determination Form (SFHDF). If the lender determines that the structure is indeed located within the SFHA and the community is participating in the NFIP, the borrower is then notified that flood insurance will be required as a condition of receiving the loan. A similar review and notification are completed whenever a loan is sold on the secondary loan market or perhaps when the lender completes a routine review of its mortgage portfolio.
