If you save 5 times what I pay, I am imaging paying like $20,000/yr for insuranceMy insurance is also through USAA. They apparently have different underwriters depending on where you live.
We are lucky, we didn't plan it, but we are up on what passes for high ground on a flat island, it would take three or four more feet of water than what we had in Isabel to get to our house, maybe the ones two blocks away that ended up being flooded pay more.
Thread drift: GET SEWER INSURANCE! We had a huge flooding storm that dumped so much water on the island that I had to tie my dinghy to a tree, it was in the front yard and was floating away. It wasn't tidal flooding, just way more water than could drain. The houses lower than us had fountains of sewage coming up from the toilets
They discovered this is not covered by standard insurance! You need sewer insurance for this. It isn't expensive, mine was about $50/year to add to homeowners.
