It sounds like LOTS more research is in order:
Is the mortgage industry in Florida right now what your husband would want to join? Does he need to be worried about layoffs and low commissions?
Are you willing to possibly pay for private school? Are there acceptable public schools in the areas you are considering?
Have you spent much time in Florida in the July and August? Can you live in the intense heat? How will you handle hurricanes?
I moved from Chicago to the Tampa area in 2004 - in a year, I was back in Chicago.
I hated it. The schools leave a lot to be desired. The traffic is horrendous. There seems to only be one way to get to and from anywhere (no 'side streets' - which Im used to in Chicago) There wasnt a whole lot of Culture. Id only heard of the "Jaws of Life" until I moved to Florida - I got to see them alllll the time. The food is very 'chain's only' - no cute little hot dog stands, or great Chinese food or wonderful pizza joints. (and this one is going to annoy some but...) Their fashion sense was months (if not years) behind - which was weird *for me*. When the hurricanes rolled through (remember, I was there for Charlie, Jeanne, Francis and on and on...) the electricity would go out for dayssssssssssssssss.... Dayssss!!! Heck, we'd have ice and snow storms in Chicago and the crews would be out there during them, getting our power back on. No electricty in July makes for a stinky, sweaty 4 days.
I hated it. My kids hated it. My husband hated it.
Dont get me wrong. Weekend Disney trips ROCKED...other then that, it stunk, IMO. Things seemed backwards.
Oh and bugs. Bugs Bugs Glorious Bugs...a giant ones. And snakes... they send out newsletters and Public Service warnings about snakes.
Granted you dont have to shovel snow, but June, July and August you cant even walk to your mailbox without breaking a sweat. The locals said we had to flip-flop our seasons...inside in the summer, outside in the winter.
Now I moved down for a new help-desk being formed. Out of me (Chicago), another Chicago person, a Boston person, a Dallas person, a Philadelphia person, another Boston person - only Philly and the other Chicago person stayed.... the rest of us left.
