Wow, 3 summers in Yuma...that's harsh. My brother lived there a couple years and I always asked him how he could stand the heat, he would always say "Ahhh, it's not that bad."

Now to each his own, but I can understand why you want to move home.
Anyway, read the first line from this website describing MD's housing market.
Maryland Housing, Baltimore, Bethesda, Columbia, Silver Spring
The MD forecast was just updated, so the info is up to date. Now don't get me wrong - MD is going through some tough times. But not nearly as bad as many, many other places. It's also potentially a good time to buy a home if you decide to come back to stay. Good luck and welcome "home."
