Dataquest's July numbers are out... San Francisco's sales increased 4.1% over last July (the other 8 Bay Area counties had fewer sales) and prices are up as well... 3.1% over last July.
So here are this year's stats:
Jan '07 - Median Price $750,000 - up 0.7% over Jan '06
Feb '07 - Median Price $757,500 - up 2.4% over Feb '06
Mar '07 - Median Price $753,000 - down 2.1% over Mar '06
Apr '07 - Median Price $790,000 - up 1.4% over Apr '06
May '07 - Median Price $835,000 - up 8.4% over May '06
June '07 - Median Price $825,000 - up 4.4% over June '06
July '07 - Median Price $799,000 - up 3.1% over July '06
Prices tend to peak in April/May when the market is at it's hottest... then cool a tad over the summer, and pick up a bit again in September/October. The bottom line though is that San Francisco remains unaffected by sub-prime woes.
A similar look at other counties will show that Solano, Sonoma, Napa, and Contra Costa counties are struggling. San Francisco... onward and upward.
