The Real Home Price
Case-Shiller Home Price to CPI Ratio
Interpretation
The real home price takes into account the effects of inflation and therefore allows for better comparison over time. The ratio in the chart above divides the Case-Shiller Home Price Index by the Consumer Price Index (CPI).
The Case-Shiller Home Price Index is a widely recognized measure of the price level of existing single-family homes in the United States. Developed by Robert J. Shiller and Karl E. Case, it is considered the leading indicator of US residential real estate prices. The index is based on a scale of Jan 2000=100 and is multiplied by 1800 to approximate the average sales price of houses sold in the United States.
When inflation is high, prices as measured by the CPI increase and the purchasing power per unit of currency decreases. The Case-Shiller index has a base of Jan 2000=100 while the CPI has a base of 1983=100. Therefore, it is the trend over time that is significant, and not the absolute ratio values.
