Yes, it is SO variable, based on proximity to the coast, age of house, what hurricane measures you have in place, etc. As I live in a 1954 house very close to the water, I don't have the proper measures such as roof tie-downs in place, and not every door/window has a Miami-Dade code approved shutter (most do, but I have 2 lower-rated shutters, and one door has a little half-moon window in it that's not up to code). So mine is probably a worst case scenario. BUT, it is a very well built house, with Dade county pine roof planking, and I was not about to mess with the roof to put the tie downs in place. At some point, I'll put hurricane resistant windows in place, and then maybe I'll be able to save SOME money on the insurance.
I haven't received my Citizen's (windstorm only) renewal notice yet, but last year it was about $2500, if I recall correctly.
Homeowner's (no windstorm) is $837.
Flood is $354.
