The reason why insurance has gotten stupid here is because of socialist mentalities. So many of you don't even understand and refuse to learn about it because you can't accept that maybe there are some negatives to socialism (there are positives too, of course).
Companies do charge higher rates by locality; however, not NEARLY enough to make up the difference. For example, a millionaire with a home on the beach may pay double in insurance but that house may be 5 times more likely to be destroyed in a hurricane. Add to that the fact that if you live 30 or more miles inland from the beach, the chances of damage requiring full house replacement go down draaaastically. Yet, people inland are forced to pay a much higher share than the risk they incur because the rich Dems and Reps have socialized the cost of insurance.
If the huge houses on the beaches of Florida actually paid even close to their risk level proportion of total damage, Florida home insurance would be much lower for everyone else.
I live 50ish miles inland from the nearest coast and, when I moved here from a place that is just 5 miles from the coast, I ended up paying over 80% of what I was paying for a larger home in an area that was about the same affluence (lack of affluence describes it better), which is how I know all of this. Put it this way, where I moved to was so much less populated that my auto insurance dropped by almost half. I went from a single dwelling house in a popular neighborhood near the coast to a townhouse in a small city that didn't even have a Starbucks when I moved here. Yet homeowner's barely declined. When I pushed the topic on the agencies I got quotes from, they all said the same thing that proportional costs are not part of home insurance in Florida.
"Has climate change changed the appeal of coastal Florida?"
No, because the actual impact of climate change isn't rising sea levels regardless what the liberal media tries to tell you. The sea levels aren't rising at any measurable significance if you read unbiased news and not doomsday liberals with an agenda or idiot cons who don't believe anything ever changes and if it does then it's bad. What IS causing problems are rising water tables due to erosion and other factors (e.g., infrastructure expansion to meet expanding population, etc.) Miami is going to be at the tipping point in the next 5-10 years most likely, if not sooner. And having 2 more hurricanes a year (Atlantic) since 1920 with average wind speeds just a tick higher due to climate change isn't even close to the top of the reasons why this is happening.
Reading and researching is a very good skill to have.
