Most homes in the Atlanta area are not in a flood zone. That means they are not in an area that requires flood insurance. Flood insurance can be very costly running from several hundred to a few thousand dollars per year. The process for determining if a home requires flood insurance can be costly as well so it is important to do a few things up front to minimize your risk.
First ask your Realtor if the home is in a flood zone. He should be able to check the tax database to see how the property is classified. If it is classified "X" this means the home is not in the 500 year flood plain and is considered low risk. This home should not require flood insurance. In addition you can visit the Floodsmart.gov website and enter the property address to do some research on your own. The website should tell you what the risk level is for the property.
Also ask your lender to verify if the home is in a flood zone. This should be done during the due-diligence period of the contract. The lender will pull a flood certification report for the property. If it is determined the home is in a high-risk area, the lender may also need to order an elevation certificate from a local surveyor before they can quote flood insurance rates. This can run $350 to $800 which is a cost that the Buyer will be required to pay.
