No good answer for the coastal states
The changes many companies are making to coverage in the coastal areas include , but are not limited to:
1. Eliminating wind & hail coverage and making the policy holder go to the state pool for it.
2. Pulling out of the coastal states completely.
3. Increasing premiums to more adequately cover their risks.
4. Refusing to write new business in the coastal areas.
You don't say what town you're in - make sure you're mapped right if in the Miami area. There used to be some quirks about being on one side or the other of the Dixie Hwy. You can always go to a higher deductible - risky unless you can afford it.
I'm assuming you have flood insurance. Ask your servicing agent for your flood policy (assuming they're not USF&G) to see if they're in a position to quote you homeowner's insurance. As Betty said, you'll need to shop around for quotes. Make sure you're dealing with reputable companies as there are a few fly-by-nights out there. You could call the Florida Consumer Hotline
http://www.fldfs.com/ and ask if they can assist you by providing a list of insurance companies offering homeowner's insurance in your area.
Now for my philosophical meandering (for which I'll apologize if you find it boring.)
The insurance companies should be able to command a premium commiserate with the risk; but, at what cost? If rates are held artificially low by the state insurance commissioners, then companies will no longer offer insurance in that state. If rates are too high, consumers cannot afford the expense.
Looking into my crystal ball (which was a discount model at K-Mart) - I expect the coastal states to eventually create state pools for homeowner's insurance for the majority of the consumers. Insurance companies will be expected to fund the pool; however, the deductibles will be high and the coverage will not be all risk.
As you can see, there is no good answer for this situation. With your September renewal, you're simply the first of hundreds of thousands of people who will get their renewal notices over the next twelve months and get the shock of their lives.
I wish you the best of luck.
