SAN FRANCISCO (CBS/AP) – A research firm says the Bay Area’s median home price surged 17 percent in just one month, to pass the half-million dollar mark for the first time in five years.

DataQuick said Wednesday that April’s median price for new and existing homes hit $510,000 in the nine-county region, up 31 percent from the same period last year. The median price rose by $74,000 during April alone, the biggest month-to-month increase in percentage terms since DataQuick began keeping track of regional sales in 1988.
