You may use reports emanating from Case-Shiller Indices to discover if the price of a target property is high, low, or stable, and perhaps you may also discover whether you should buy or sell. For example, using data collected in September 2013, the S&P/Case-Shiller Indices shows that U.S. home prices rose 3.2% in the third quarter of 2013, and 11.2% over the past four quarters. In order to confirm this trend, you must analyze data near your target property, but national results indicate an increasing price trend.
