We have moved alot in our lives with both my wife and I being military, One resource I wished we had then was this website.

http://www.city-data.com/

We have used it for many moves since its inception. It is full of good info. But for us it was always best to plan a trip to the area to get a feel and look at real estate before making a final decision. FWIW we lived in Rockville, MD while stationed at Walter Reed. It is an interesting area for sure. One thing it is not is CHEAP or car hobby friendly. Western MD seems very nice from our trips out that way. Mason Dixon dragway is a nice small track as well.
