I think there is more to it than that. I think it has to do with how insurance companies are designed/regulated. I don't know when, but regulation changed awhile back that allows insurance companies to work like investment companies. Years ago, insurance companies where limited on what/how they could invest, it had to be utilities or bonds or something like that. Now I think they can invest in anything, so when those investments do well, the premiums don't go up as much, then those investments do bad, premiums go up more (the company makes their profit no matter how).
I'd like to see Florida tell the insurance companies that if they offer Auto coverage you have to offer homeowners too. This way they can't just cherry pick the most profitable products to sell. If Progressive wants to sell auto insurance in FL, they should offer their homeowners insurance too.
For me, it's time to sell the jeep... I can't justify the insurance for how little I drive it.
I wasn't suggesting what I outlined to be the only issue, just that there's a correlation between insurance and natural disasters and that has a massive impact, not particularely a news flash. Keep in mind those same carriers that are investing in whatever they want aren't jacking rates insanely and/or pulling out of other states... I'm in PA & I don't know of any carriers that have packed up & left, & my homeowners and auto rates have gone up around 50% BUT spread out over the course of 25 years, basically commensurate with inflation. Although we did manage to get one significant hurricane here during that time which was Sandy in 2012, PA is generally not a big natural disaster state, see below. Stability in that respect has resulted in stability in homeowner's insurance rates, I believe.
