One option may be to take a lesson from the RV folks. I don't recall the specific about FL, but TX allows you to have a mail forwarding service as your official domicile/driver's license address. With a mail forwarding service as a home base address, you can test out many different areas until you find the one you want to stay at. That will save you from having to commit to a location only to find, after a while, you don't really care for it as much as you thought you might. It might also be handy if you want to migrate between midwest family locations and points further south in winter.
Florida allows the same, hence the success of St. Brendan's Isle which is more like a mail forwarding service on steroids.
This is a common practice of RV'ers, Cruisers, and traveling nurses, among others.
