Years ago, State Farm and Allstate both tried to get out of offering homeowners policies in Florida because of the hurricanes. The state told them that they could stop offering homeowners policies but that they would also be banned from offering auto policies in that case. That changed their tune dramatically.
When my homeowners policy was dropped because that company left the state of Florida, I tried both State Farm and Allstate for a policy. State Farm was servicing present policy holders but was not offering new ones and Allstate wouldn't insure me because my house was valued under $100,000. I had to go into a state "pool" for insurance and ended up with some company out of New Hampshire. They then tried to cancel my insurance because there was a city-owned tree on city-owned property that "might" fall on my house one day. Nothing wrong with the tree, mind you, but it "might" fall. They didn't mention anything about a comet that "might" fall on my house or that Godzilla "might" rampage through Orlando, but I'm sure their actuaries had those circumstances on a list somewhere. Getting the city to trim the tree and the mention of getting a lawyer seemed to make them back down on the threat. They also tried to make me get flood insurance, but since my house was the highest point in the neighborhood with three roads running down from my lot, I wasn't buying that. If I had to worry about water coming into my house in that neighborhood, I had more to worry about than the flood; I'd need to start building an ark.
You do have to remember, though, that insurance companies don't exist for your advantage......they're in it to make $$$$$.
