Total listing inventory is creeping up, however, there is still a significant shortage of detached homes for sale on the Westside (only 342).  So far in January, the number of sales are lagging from December/09, but sales are slowly increasing.  The sale to list ratio over the past week was 33% (104 units were reported sold).  Moving forward into 2010, the listing inventory will be a key factor in what happens with prices.
