This is the first entry of a series based on a presentation made by Julie Hansen, Professor of Economics, WWU.
This graph shows home sales (dark blue) from 1986 through 2009, and single family building permits (light blue/green) during the same period. It's interesting to see that current homes sales are almost down at the level they were in 1986, and building permits are nearly exactly at the level they were in 1986.
Also notice that home sales peaked in 2004, and building permits peakd in 2005.
Notice that homes sales have fallen to less than half of what they were at the peak in 2004. However, building permits have fallen to less than a third of what they were in 2005.
This graph does not show data for 2010 which indicates that homes sales and building permits have leveled off and are no longer in decline.
