First I would figure out where jobs are available in your field.
One of the best school districts is Brevard county. Usually in the top for math and science competitions; but like all counties; the budget cuts are hitting hard, teachers will be laid off, schools closed, programs dropped, less bus transport, no field trips, etc. . Most areas in Florida looking to drop sports, arts, have bigger classes with no assiastants in the classrooms as the first move. We have had charter schools shut down because they just can't make it. They are even considering letting school groups make money for the schools by allowing gambling like BINGO etc. Might not be the time to consider education for your kids in Florida.
That said houses have come way down. You can probably buy a descent house for $125,000 now with all the foreclosures down here. It might be on a street with ruts that can eat your car because cities are running out of money for repairs. Projects are being tabled. Most of us are living in houses worth $100,000 less than we paid for them if we bought in the last 5-10 years or so.
Jobs are getting scarcer. All I could find when I lost mine was part time with no benefits almost. I counted going back to teaching, but quickly found out that ain't happening unless at a daycare. With the shuttle going away in 2010 it probably means a lot more job cuts because of the tech people leaving the county in masses. I found out one of my favorite fast food places to eat ( Moes Southwest Grill) was closed yesterday when I went to go eat there. Have no idea when it shut down but it is gone and they always seemed to have a lot of people there.
Not looking rosy down here, but seems that is pretty much the picture everywhere. Find a job first, but remember that even having a job lined up doesn't mean the job will be here when you get here or for 6 months after you make the move.
