$350K - a nice 3BR condo? Where?
My wife and I sold our 624 sq. ft. one bedroom apartment for $340 last year. My neighbor (who is in D.C., not Virginia - so there is a difference) just sold her 800 sq. ft. one bedroom for a whopping $525!
Ashburn should be a little cheaper. It's really quite nice out there. You'll be very close to Horse Country (Virginia raises more horses within its borders than every state in the union, save two - KY and TX), which is gorgeous country. In addition, there are some really nice golf courses, crime is virtually non-existent, and UVA is a short commute for your kids when they get to be college age.
Welcome home, my friend. I've spent my whole life here, and don't see myself leaving the area any time soon.
