Just a clarification on the difference between Jed's and my date of the height of the market: I use a three-month moving average of median values for my charts because it smooths out seasonal fluctuations. Jed also combines condos and single family homes for his numbers, whereas I track homes and condos separately. Both methodologies are equally valid -- just be certain you know what you're looking at.
The actual high for single family homes, according to my methodology was in May 2007, when homes reached a high of $965,000 (median).
Interestingly, the all-time high for condos/TICS occurred over a year later in July 2008, with a high median price of $776,125. You can see my chart comparing home and condo/tic values here: http://www.pegasusventures.net/wordpressblog/2009/07/22/surp
