Sharat Ahuja, realtor, Long & Foster, Fairfax, and Terra Firma Realty Group “I work mostly in the Fair Oaks area, the 22030, 31 and 33 zip codes. What I see are prices going up overall, slowly. Not as fast as areas closer in, but still improving. Inventory is very low. Some people are waiting to see prices getting back more to 2005-2006. But if a house is priced right, it can sell quite fast.”
