Fewer Foreclosure Resales the Key Difference in the New Case-Schiller Indexes

How much did home prices fall during the housing market crash? According to the new monthly CoreLogic Case-Shiller National Home Price Index, U.S. prices fell by 27 percent. But if measured by the old, quarterly Case-Shiller index, the peak-to-trough decline was 35 percent. So why do two home price indexes, both calculated using the same Case-Shiller methodology, differ so noticeably on the magnitude of the home price crash? The simple answer is because they are not tracking identical populations of housing transactions.

The new CoreLogic Case-Shiller indexes are estimated using CoreLogic public-deed record data, while the old indexes used data from other vendors. In general, the newly incorporated CoreLogic data provides more detailed and comprehensive information about individual property transactions and broader geographic coverage than the data sources previously had. These differences in turn generate different populations of repeat-sales pairs – the observations that are used to estimate our repeat-sales indexes.
