With my last house, I inquired about getting flood insurance becuase of it's proximity to a lake. I was quoted more than my mortgage for flood insurance because I wasn't in a designated flood zone.When a hurricane flooded a town near where I used to live over 20 years ago, numerous homes were lost. Their owners said they had been told they "didn't need" flood insurance or the insurance "wasn't available to them".
Meanwhile, the lot across the street and the neighbor next to me were in flood zones and they were 3' higher than me.
I lost a bunch of stuff in the garage when my lot flooded 8/2021. Thankfully it didn't get into the house, but I don't care to go through that again.
