flood zones and real estate

Today I learned a valuable lesson about the accuracy (or inaccuracy) of the flood zone designation from our municipal tax database. I’ve known not to rely on the square footage or even the number of bedrooms listed in the tax assessor’s database, but I’ve always assumed that the flood zone designation was accurate. I have since learned that with FEMA constantly changing the flood hazard maps, a property that may have been designated outside of a floodplain a few years ago may now actually be located within a hazardous boundary.

What does this mean to you as an investor? Buying a property in a high-risk flood zone could mean additional expenses including a flood survey as well as ongoing flood insurance.  In addition to this, it could make the home more difficult to sell at some point in the future as a result of this designation (not to mention the expense and headache associated with a flooded property).  Flood insurance alone can be anywhere from a few hundred dollars a year all the way up to a few thousand a year, depending on the flood zone category. The bottom line is any property purchase should be made with full knowledge and awareness of the property’s flood zone designation.

Going forward, we have implemented a policy in my office to run official flood certifications on any new properties we put under contract. Rather than rely on our local tax database or even some of the free flood zone sites online (which we have also found to be inaccurate), we have partnered with a local lender to run this for us . We also have an insurance agent that can run flood certs as well. Most investors have a good relationship with either an insurance agent or loan officer that would be willing to help in this area – don't be afraid to utilize these relationships for this valuable information.

As an aside, if you do discover that a property you have purchased is in a flood plain, consider carefully what kind of flood insurance coverage you want. It may be that your lender requires flood insurance, but doesn’t necessarily dictate how much coverage you need. If this is the case and you feel confident that the property won’t flood, you may be able to elect to cover only the building (not contents), insure for a lesser dollar amount, or carry a higher deductible. In doing so, you can lessen the impact that flood insurance has on your cash flow by obtaining a policy with a smaller yearly premium.

For more information on the National Flood Insurance Program, check out the official government website at But even more importantly, make sure you have the ability to determine the flood zone of a property before you buy it. The last thing a real estate investor wants is a property with unexpected risk and expenses cutting into future profit.

    I bought several homes in nice areas 4 feet above flood stage. Both are atleast 3 feet higher than that and one is right behind the city court house. A couple of years ago FEMA came in and label the whole city a flood zone were no flood has ever occured. They said on their site don’t even bother trying to get out of it, you WILL NOT WIN! I guess they need the money. Did a lot of good checking things out before buying. Moral of story, paid off the mortgages, NO FLOOD INSURANCES.

    Ken – It took me a while to put that on my checklist when buying a property; “Check to see if it’s in a flood plain”. It only took one mistake for me to remember. Sometimes you just can’t tell by looking at the area. I have found that houses I never dreamed were in a flood plain were actually in one. As a wholesaler, I can tell you from experience, they are harder to sell in my area.
