I think that it really involves money management, and setting goals for the future.

Yes, homes in Fairfax, MoCo, and Loundon are going for 700+, but homes in PW, Stafford, F'Burg and the like are going for 350+ for a couple thousand square ft.

I have known several people making making about 40k, that were able to live(not survive) comfortably in Prince William.

Now if you want to live in Great Falls, and drive an 06 something; 70k+ wont be enough. But if you are willing to look(really look) for a place, and manage money, think know youll be just fine.

BTW-Town homes in F'Burg are renting for about 850 a month, my girl just got a place down there, right off of Rt. 3
