Lawrence Yun, NAR chief economist, says the wave of sales activity the last two months represents a convincing autumn revival for the housing market. "October's strong sales gain was widespread throughout the country and can be attributed to the release of the unrealized pent-up demand that held back many would-be buyers over the summer because of tight supply," he said. "Buyers are having more success lately despite low inventory and prices that continue to swiftly rise above incomes."
