The Florida homeowner insurance crisis is not a new one. It started way back in 1992 when Hurricane Andrew roared through southern Dade, destroying tens of thousands of homes. It wasn't long after that before the smaller insurance companies went under, and the larger companies such as State Farm realized they had kept their rates far too low for too long.
So they started raising the rates. When I bought my house in near Ft. Lauderdale in 1994, my homeowner's rate was about $600, a bit less than I'm paying now. Of course, I had to take out flood insurance to the tune of $400, so I was a paying about a grand for insurance that first year. Each year after that, it went up, and the rate of increase actually accelerated around the turn of the century. My rates soared past a $1000, then $1500, and then cracked the $2000 barrier a couple years before we sold. At the time of sale, I think we were paying $2400 for watered-down insurance (5% deductible, etc), while the flood was around $450. Had we stayed one more year longer, we'd had to pay another 20-25% on top of that. Ouch!
Tyler is right - if an area is too expensive to live in, MOVE. Boy, that was the smartest move I ever made...LOL. Came up to Atlanta and found out I could insure a house bigger than the one in Ft. Lauderdale for the amazing sum of $630 a year, no flood needed. I thought I had died and gone to heaven...hehe.
If a Cat 5 were to ever hit South Florida head-on, it would mean the end of private homeowner's insurance. This would devastate the real estate market to the point that approximately 40% of Florida's population would have to move out of the state - as so few people would be able to afford to own a house without a mortgage - and there simply wouldn't be enough rentals to take up the slack. They might end up passing a law stating that mortgage companies could no longer require hurricane insurance coverage for existing note holders, but there would be no new mortgages written, that's for sure...LOL.
When it comes down to it, Florida is going to have to revert to a backwater, low-population state dominated by cheapo (i.e. disposable) $20,000 shacks for snowbirds to winterover in, as opposed to the massively over-developed nightmare it is today.
I, for one, can't wait for that to happen. Bring on the Cat 5s!

Nowhere to run, nowhere to hide...
