@Joe Henry, I too have been searching for that same type of information myself only I'd like to broaden the search to historical prices in my local market, Kansas City, over the previous 30 years. Thus far I haven't found much more luck than it appears you have.
I had an epiphany after listening to the Serge Shukhat's podcast #60. Here's a bit of the transcript:
"Okay, looking at the analytics and the pure metrics of the real estate market in Metro Phoenix.” I looked at the—I still remember this one graph that showed income as a proportion—income to real estate prices. The ratio of income for the Metro Phoenix area to the cost of real estate and the relationship over the past 30 years and that real estate always, Arizona is a cyclical market, very ups, very fast downs.
It would always fall at a very specific ratio, which was defined as equilibrium, okay. Over the 30 years, it was always, homes were always trading at that equilibrium price. Low and behold by the end of Q1 2009, we were probable 70% below that equilibrium price. What I saw was that we were—that the market had over corrected to a point where it was just—it was a no brainer—it was a no brainer."
This made me totally change my philosophy behind when to purchase buy and hold, and when flipping is more profitable. What if there were a way to look at historical prices of homes in a specific market, and plot those prices on a graph next to any other number of values as well such as employment rate, or average income, ect. The investor armed with that information would be much better equiped to know what the intrinsic values of these homes are and not what the whimsical market demands right now.
Have you had any luck since this post in finding this info?
