S&P/Case-Shiller Home Price Indices Year-over-Year Change

Comparing all the home price indices, it needs to be understood each of the indices uses a unique methodology in compiling their index – and no index is perfect. The National Association of Realtors normally shows exaggerated movements which likely is due to inclusion of more higher value homes.
