Depends on your criteria.
Are you looking only at detached single family homes? What size home -- there are so many nice and cute bungalows, but there are also very large homes that have sold
i can send you charts showing median sold compared to median or sale from 2007-2010 to compare supply and demand, days on market to show inventory levels, etc.
Let me know..,,or wait a few minutes and I can give you a general overview
In the meantime, here's a link to Trulia's report on market activity/values in Berkeley Hills
http://www.trulia.com/real_estate/Berkeley_Hills-Berkeley/527/market-trends/ which show median salesprice at $724K, a 12% decrease compared to prior year.
