Considering that real estate is in the dump right now, no sense in considering selling the old place just yet. You might keep it for your summer home, and winter over in Arizona.

I really like Wyoming in the summer. Nice countryside and no state income taxes! I think it would be a great place for summer, and winter in Florida (also cheap real estate right now + no state income taxes). Or, you can do winters in Belize (English-speaking country in Central America), or even better, Panama.
