The inimitable Case-Shiller family of regional real estate indices adopt a repeat sales methodology to control for the ever-changing composition of housing stock, but still lack a measure of geographic transitivity that challenges comparisons across markets. Haus.com’s Common Haus Price Index (CHPI) normalizes for housing stock tracked across regions by focusing the asking price of the “most common American home: a three-bed, two-bath, 1,600-square-foot home built in 1977 on a 7,500-square-foot lot.” Moreover, the lag between measure and report is just over two weeks, versus the 1-3 month lag of most other home indices.
While there are a number of considerations, including the supply of the “most common American home” within specific markets and the focus on asking price, this is a very intriguing step forward in transforming home indices from essentially descriptive to something approaching prescriptive.
