According to this report from NAHB Winston-Salem is one of twenty three housing markets in the US showing sustained improvement:
The IMI is designed to track housing markets throughout the country that are showing signs of improving economic health. The index measures three sets of independent monthly data to get a mark on the top improving Metropolitan Statistical Areas. The three indicators that are analyzed are employment growth from the Bureau of Labor Statistics, house price appreciation from Freddie Mac, and single-family housing permit growth from the U.S. Census Bureau. NAHB uses the latest available data from these sources to generate a list of improving markets. A metro area must see improvement in all three areas for at least six months following their respective troughs before being included on the improving markets list.
