I'm not sure how useful it is to talk about the Bay Area as one market. During 2006-2010 things were very different from one zip code to another. I was just looking at some historical Zillow data from those years and some zip codes like Cupertino barely moved at all, for all those months. Others, like parts of San Jose dropped by as much as 50% and just recovered to their 2006 numbers recently. So maybe for some general sense of the numbers you can average the Bay Area market but when it comes to pricing an actual house and trying to see how recession-proof/prone it is, thinking of the entire SF Bay doesn't seem to make sense.
