Each time you make, inrease, extend, or renew a loan you’re required to determine if the property is in a special flood hazard area. You may rely on an existing determination if it isn’t more than seven years old, is on a SFHDF, and there have been no map changes. You’ll want to make sure the life of loan monitoring is extended to cover any modification of the term of the existing loan or to cover a new loan on the same property. You will need to provide a new Special Flood Hazards Notice to the borrower even if you are using an existing determination.
