I'd suggest somewhere other than Florida, honestly. East central, central-central Florida and southeast Florida are extremely bike-unfriendly. I can't speak for other parts of the state (and it is a surprisingly big state with several distinct and culturally very different regions) - but what I read isn't encouraging. Still, I know next to nothing about Tampa, and the northeastern inland side wouldn't be too far from some of the state's best biking in Lake County.
Western North Carolina has been popular for many years with outdoors-people of all stripes. I haven't looked there in a while, but I'd have to think the real estate boom has slacked off there as it has in the rest of the country, so it might be a good time to buy. Some friends of mine in their 70s just sold their coastal Florida home and moved full-time to a condo in Asheville. Neither of them would ride the roads in Florida any more, just too dangerous, though I don't know if they've revisited road cycling at all now that they've moved.
