Southern California homes sales spiked in December compared to November, but remain well below 2009 levels due to a sluggish job market, tight credit and few new home sales. San Diego-based data firm DataQuick said 19,528 new and resale homes and condos sold in Southern California in December, down 12.5% compared to December 2009, but up 20.5% from November. DataQuick's latest report covers Los Angeles, Riverside, San Diego, Ventura, San Bernardino and Orange counties. “Ultra-low mortgage rates, coupled with lower prices, gave the market a boost this fall, helping to explain the above-average gain in closings between November and December," said John Walsh, president of the data firm. DataQuick said the average gain between the two months is 12.9%. Despite the gain, Southern California home sales hit the lowest number recorded in a December since 2007 when only 13,240 homes sold. New home sales hit the lowest record for a December ever recorded by DataQuick. New home sales for all of 2010 also hit a record low. Foreclosure resales accounted for 34.3% of the resale market in December, down from 35.2% in November and down from 29.6% one year ago. Foreclosure resales hit a low this year of 32.8% in June and had generally trended slightly higher until last month. The peak was in February 2009 at 56.7%, DataQuick reported. The median price for a SoCal home last month was $290,000, up 1% from $287,000 in November. In December 2009, the average price was $289,000, according to DataQuick. At the county level last month, the overall median sale price fell on a year-over-year basis in Los Angeles (down 2.7%), Orange (down 5.7%), San Bernardino (down 1.3%) and Ventura (down 1.4%) counties, while San Diego and Riverside counties recorded small gains of 0.9 % and 2%, respectively. With regard to upcoming home-buying activity in the area, Walsh said there's "potential for sales to perk up this spring if rates stay low and brighter economic news lifts consumer confidence."
