(RECAP: Buyers in Northern Virginia face a limited supply of homes, particularly for first-time buyers, says Nela Richardson, chief economist for Redfin real estate brokerage in Washington. Unlike suburban Maryland, where prices vary widely between Montgomery and Prince George’s counties, prices in Northern Virginia are relatively high everywhere. The highest prices are typically in neighborhoods closest to the District such as Arlington, McLean and Alexandria. Overall in Northern Virginia, median home sale prices from January through August 2016 rose just 0.5 percent to $432,000 from $430,000 in that same period in 2015.)
