I wish I did back in 2016 with the Baton Rouge flooding. Wasn't required to have flood insurance, so I didnt. House took on water. Not much, but enough to make a mess of things. Expensive lesson.
It was honestly never even a consideration for me not to have flood insurance. The first house I owned required it and flooded in Katrina. The second house I owned required flood insurance and it flooded in Isaac. So there was no way that I was not going to have flood insurance on the third house I bought.
The cost has gone up over the years, but its still worth the cost to pay for flood insurance. But I can certainly understand why people who lived in areas of Baton Rouge that had never flooded would not have it. Nobody really knew at the time that all that development was going to cause wide spread flooding.
