The median price of a home in Southern California surged 6.4 percent in June from May to the highest level in 30 months.
The price is still down 26.4 percent from $360,000 a year ago.
DataQuick attributes the jump to an increasing number of deals above $500,000, as buyers responded to price cuts and found it easier to secure financing.
