Lots of insurers have left the Florida markets entirely, because they're spending more paying out claims than they can take in for premiums. The ones that remain have sky-high premiums, thousands of dollars each month in some cases, because they're pretty sure that they will have to pay out claims. The result is that many homeowners in Florida can no longer afford insurance. Since you need to have insurance on a home in order to get a mortgage, that makes buying a home in Florida really expensive, unless you can pay cash up front.
