Hi, Ashburn VA is a beautiful family community where I live with neighborhoods that range considerably in price from older established home to brand new building. Ashburn Farm is a neighborhood that is lovely and not so new that it is very expensive. I also think Ashburn Village is very reasonably priced but a little larger and a little older. Broadlands and Brambleton are the newer neighborhoods.
Sterling VA is more eastern and Leesburg VA is more western and some areas are very nice although I personally think there are a few sketchy neighborhoods in those towns so you want to pick carefully the neighborhood and school district. Chantilly, Herndon, Centreville, and Reston are also probably good choices as near to Dulles.
I am sure a realtor would be happy to talk to them via telephone. And if they have any particular questions, feel free to message me. Dulles is a really great suburban area. I wish my husband could get a job here. But he works over an hour away in Alexandria.
