This is an interesting chart. A couple of points jump out at me.
1. Prospective buyers dropped off precipitous in 2006. I wish we would have been watching this statistic in 2006! It seems obvious when you look at this chart.
2. Case-Shiller has always been a tough metric for me to get my arms around.
Came across this video the other day and it is a great, simplified, graphic illustration of the housing crisis we just went through. Share it with some of your friends or family who maybe did not understand what was happening or did not take the time to study it. It is kind of like School House Rock for adults! There is a clever little graphic presentation on leverage between minutes 2:00 and 3:15.
