Yes, REI. The purpose of the Case Shiler index is to look at base pairs of maintaned, but unmodified SFD's. The purpose is to look how market trends affect the value of an "unchanged" home over time.
I must admitted to some trepidation over deffending the work of the premiere macroeconomist of or time when dealing with the housing issue.
Please be advised that he was the only one to "call the bubble" when he explained "a history of home values" in 2005. Please look into his book called "irrational exuberance".
Please also be advised that when one includes things like new homes in an index, things like seller insentives can vastly effect the real value of the home.
For "Makessence",
Yes, history will repeat itself. But the question that I am looking at is: How quickly home values will reach levels more in line with historic Values. For instance, in the Japanese Bubble in the early 1980's, prices droped sharply for a year or two until the government steped in to stabalize them. This resulted in flat home values for a decade.
I can't attached a study of how Japanese prices reacted from 1980 to 2005 or so because it is 1.45MB. This is good resent history with this title:

I can forward this in depth study of how the Japanese maket played out to anyone who requests it.
Yes, history will repeat itself, but the devel is in the details. Home prices will fall from here, but, how far? for how long? and when they will start back up? have to many variables to predict with certainty.
I'm not a guru, but I do my home work.
Robert Shiller for God!
Opinions are like ********. We all have won. I hope I'm not seen as the latter. :D
