Hi,
I grew up in Alexandria Va. a suburb of D.C. Actually, it's the Mt. Vernon area. Housing in the D.C. area is high but apparently the housing market has changed. It's more a buyers market but still high. Va is a great place to live and Fairfax county has a great school system as does Prince William county. Woodbridge, Dale City are in PW county which is south of Fairfax county /Mt. Vernon. FF county has grown so much since I was living there. Not sure if you have kids but if you do that's something to consider(school system). It use to be, not sure about now, that the farther west you lived in Va the lower cost of housing. The Mt. Vernon area is HIGH!!
My sister lives in Clinton Md. where the cost of housing isn't as high as Va. I don't think Md. has the personal property tax that Va. has. I could be wrong on that. Montgomery county, Md. is nice.
I've lived, pretty much, all over the world as an adult (military) and I have to say that I really appreciate that I was raised in the D.C. area. So much to do and see. Majority of my family (extended) lives in the city (I refer to it as the District) or Maryland.
Since retiring from the military we have settled in Va. Beach, Va. Your money goes a little farther down here then up there but I'm only 3 hrs away from home and that's nice.
Good luck w/ your move I think you'll love that area.
