Data Nerds & Economists: Seeking Solid Real Estate Data

[Cary F.]

Looking for some help from all the engineers, bankers, economists, mathematicians or other quant people that might be out there. I've been looking for solid real estate related data sets online. I'm looking to do some statistical computing to analyze pricing patterns, demand metrics, bubble risk, etc.

Most of the data sets I see out there are either limited in observation or are just downright messy. I'm looking for some data to read into some SAS programs. If there are any Cleveland, Ohio investors who know of good local data, please let me know that as well!

Thanks in advance! Oh and feel free to connect with me if you're a data/analytics based thinker.
