Well, I actually just moved from Tucson after living there for almost 4 years.
We were renting, so not sure about home costs and things like that.
There are some other guys on TDH who are still living in Tucson, Jarvis and Firstsonofsolo live in Tucson. There are a few other 501st guys down there, too, but I don't know if they're on TDH or not.
Jimmy BUFFett lives in Phoenix and he works in the flying industry as well. They'd probably be able to give you more info.
