How flood insurance works
You may be surprised to learn that your property insurance doesn’t cover flood damage. That’s because flood insurance policies are generally purchased separately through government programs.
Most flood insurance coverage is offered by the National Flood Insurance Program.

The cost of flood insurance can vary depending on a number of factors including:
Most importantly, your flood risk. Areas with a higher risk of flooding will have a higher flood insurance cost.
The amount of possessions you’re protecting with your new flood insurance coverage.
The type of property you are protecting; primary residence, nonresidential property or second homes.
Considering all of these factors, the average cost of flood insurance through the National Flood Insurance Program is about $700 per year. (3)
