Check realtytrac.com for foreclosure information in and around San Ramon. I counted pre-foreclosure (NOD) average 50 filings per month in San Ramon. That rate is getting worse recently. The NOD is a leading indicator of future foreclosure which strongly correlated to house price downward movement. Within 6 months, about 30 out of these 50 NODs (some of them are duplicate, and some will manage become current again) will eventually join already large distressed property inventory (either REO or short sale). That will be accounted for 50% of total re-sale homes in San Ramon per month. House price will not stabilize as long as distressed property inventory is till high.
