That is all Central/South Florida. North is usually considered Jacksonville west to Pensacola.
It really depends where you want to live and what your budget is. There are nice areas in every location, South Tampa, Clearwater Beach, St. Pete Beach, and some areas of Brandon for the Tampa area. Then in the Miami-Dade Broward County areas you have places like Weston, Miramar, etc. The downside is that from MD&B it is a 3-31/2 hour drive to the Tampa Area.
I would stay away from Orlando. It is very touristy and everyone I know from there goes nuts.
