Many home buyers in the D.C. region see Arlington as an ideal place to live. It’s outside the city limits yet offers quick access to downtown D.C., walkability, public transportation and parks. That desirability means home prices are high in the Northern Virginia suburb. In May, the median sales price for a home in Arlington was $676,200, according to Bright MLS, higher than the median sales price of $650,000 in D.C.
