From my TeamIrene blog:
Here are the October 2009 housing inventory supply numbers going back five years for selected Eastside areas.* Months of Inventory (MOI) refers to the number of months it would take the current housing supply to be completely sold if no new listings were added. (Lower numbers = more seller-friendly market.)
The geographical area is marked at the top left of each chart. You can also click here to view stats for all Seattle and Eastside areas (opens as a pdf.)
