It may be possible to get your home removed from a flood zone(technically, removed from a Special Flood Hazard Area), ultimately saving homeowners from lender-required flood insurance premiums.
Being required to carry flood insurance when only part of a structure lies in a flood zone has driven many home owners crazy. In some similar cases, we no longer require flood insurance for a conventional mortgage.
If you are thinking about buying a home and want to get a flood insurance quote, it’s pretty much pointless to do so if you don’t get an elevation certificate. Without it, an insurance agent will typically quote you with the highest premium for that given flood zone instead of a more accurate one.
