LA JOLLA, Calif. ( DQNews) -- The Bay Area's housing market rounded out 2011 much the way it started it: with constricted and atypical sales activity, lots of bottom feeding, and a largely dormant mid- to move-up market. Sales were up slightly last month, while prices dropped, a real estate information service reported.A total of 7,494 new and resale houses and condos sold in the nine-county Bay Area in December. That was up 18.6% from 6,317 in November, and up 4.4% from 7,178 in December 2010. The year-over-year increase was the sixth in a row, according to San Diego-based DataQuick. "We'll remember 2011 as much for what didn't happen as for what did. People put discretionary buying and selling on hold, except at the very top of the market. The spectacular gains in affordability, based on the combination of lower prices and ultra-low interest rates, was largely theoretical for many people because it was so hard to get a mortgage. That, combined with negative equity and economic uncertainty, kept people away," said John Walsh, DataQuick president. "Many of the deals that did make their way through the system were in the distressed arena - foreclosures and short sales. Much of it was deeply discounted cash purchases, disproportionately at the lower end of the price scale," he said. The median price paid for all new and resale houses and condos sold in the Bay Area last month was $351,500. That was down 3.5% from $363,500 in November, and down 6.3% from $375,000 in December 2010. The median has declined on a year-over-year basis for the last fifteen months. Last month distressed property sales -- the combination of foreclosure resales and "short sales" -- rose to 49.6% of the resale market. That was up from 45.9% in November and up from 48.2% from December 2010. Last month 31.4% of Bay Area sales were for $500,000 or more, down from a revised 32% in November, and down from 35% in December 2010. Government-insured FHA home purchase loans, a popular choice among first-time buyers, accounted for 23.4% of all Bay Area home purchase mortgages in December, up from 21% in November and up from 23.2% a year earlier.
