Low inventory couple with limited number of properties for sale in Santa Clara County, multiple offers are common. On the last day of May, there were 1,663 homes and condos for sale in the county. That was up a smidge from 1,552 in April, but way down from the 3,167 properties for sale in May 2011. That is a 48% decline. There is no easy fix for the inventory problem. While this tough on buyers, sellers are very happy.
