Marin County Real Estate Market Trends

It appears we've been "bouncing off the bottom" for a couple of months now. Investors and first time buyers have realized the opportunities out there.  There appears to be a pick up in property sales in all price ranges the last few weeks. The question is, as we bounce off the bottom, will this market get some lift?  Are the recent sales just seasonal? Or, does this reflect  we've hit the bottom, and are moving forward?
