Data sources and methodology:
- Latest quarterly, median, existing, single-family home price provided by the National Association of Realtors.
- Trailing house price index data provided by Standard & Poors.
- Inflation data provided by the U.S. Department of Labor's Bureau of Labor Statistics.
The chart on this page estimates the market value of today's median-priced house over a 18-year period. The trailing nominal prices are derived by taking the recent median price of existing single-family homes, as reported by the National Association of Realtors, and discounting it by the S&P/Case-Shiller Home Price Index. The S&P/Case-Shiller HPI is a "constant quality" index, so even though houses are built larger today than they were 18 years ago, this graph automatically adjusts for this variation. The trailing real prices are then derived by adjusting the nominal prices by the CPI - All items less shelter.
