We were the first and only company in the Chicago area to analyze the real estate market in a comprehensive, aggregate manner (before Zillow). Utilizing custom mapping software and statistical methods, we built maps to show residential property values, appreciation, depreciation, and other real estate market trends. Our products were used by consumers, Realtors, developers, investors, city planners, and businesses in Chicago and the surrounding suburbs. We answered questions like: "How strongly is the price of a property tied to mortgage rates?" and "Can I see a map of all home sales in a particular area for the past year?" and "Is there a housing bubble in this neighborhood?". All analyses were customized to the specific needs of the client in order to provide a comprehensive understanding of the locations they were looking at. We were one of the first to empirically demonstrate that there was a real estate bubble in 2005, based on mortgage rates alone. When we added sub-prime mortgage data and re-finances to the equations, the bubble looked even worse. This news was a tough sell to people who wanted to buy a home, though. Ultimately, the company closed was sold to Zillow in 2006.
