One of my customers asked me about what is the current housing market now? so I did a comparison of the silicon valley (Santa Clara County) real estate market comparison for September 2007 and last year September 2008. I use the Median sold price for Santa Clara County. The Monte Sereno has the most gain 33%  and followed by the Los Altos for 3%. The Los Alto Hills declined -40% and followed by San Jose declined 33%. The county wise lose 11%.
