My neighbors have a house in Naples (their full time house) and several pieces of commercial real estate down there. They said their house value is crapping out but their commercial ventures are going great and they are buying more.
All the FL retirees are moving to my neck of the woods - my house has more than doubled in value in 6 years and land is appreciating even more. YAY!
Now I just need to decide when to start selling and move further out ;)
