The piece specifically references local John L. Scott CEO, Lennox Scott, who is quoted as saying "King County is built out" and that "a lot of the new single-family-home development is going into the Tacoma area." Additionally, the article references the major price disparity between Seattle and Tacoma as a reason why Tacoma will appreciate more rapidly than the average city.

This is not the first time I've seen national stories predicting nice appreciation particularly in Tacoma, and we currently have a bunch of active investors who have been seeking out investment properties in the Tacoma area largely due to the affordability. Even so, overall demand has remained modest in Pierce County as a whole, and the volume of closed single family sales for 2010 dipped slightly from 2009. Prices did, however, remain rather flat.

Will Tacoma perform well in the next 1-2 years? Time will tell, but in the meantime I think we can at least all agree that it has many more affordable options.
