I live in South Florida.

The ONLY one that can answer this question is your agent. Without lots of other information, a number can't even be guessed properly.
No one here would know. There are many other factor like the many discounts your insurance company offer, like multi-car discount, multi-line discount, good student discount, worthy driver discount and others.

Only your agent would know. Give your agent a call.
