What to know when your lender determines your structure/property is in the floodplain and what options you have:
Anyone who applies for a federally-funded mortgage/loan or refinancing on an existing home in flood-prone areas will be required to carry flood insurance for the life of the mortgage/loan. Generally, the only documentation that lenders will accept to change their floodplain determination is a FEMA Letter of Map Amendment. For more information, see the links below.
