Home Price Index (HPI)
Definition
The Home Price Index (HPI) tracks the value changes in residential housing over time. Unlike average or median house prices, the HPI is anchored to a base value and reflects price level changes, which help real estate investors, analysts, and policymakers understand market trends and performance.
Purpose
The primary purpose of an HPI is to provide an economical and systematic approach to understanding how housing prices are evolving over time within a particular geographical region or market segment. It helps in gauging the health of the real estate market and can be a critical tool for making informed investment and policy decisions.
Calculation
The Home Price Index is typically calculated using repeat sales of the same houses to track price changes accurately. Several methodologies are used, with the most common being the repeat-sales method, hedonic regression, and the purchase-only index.
Examples
- Case-Shiller/S&P Home Price Index: This widely known index covers multiple cities in the United States and is highly cited for understanding regional and national trends.
- Federal Housing Finance Agency (FHFA) Index: Uses purchase data from conforming, conventional mortgages to measure changes in single-family house prices across the United States.
- Local Market Index: A local index might track housing price changes within a specific metropolitan area. For example, an index might show that the home prices in Chicago have increased by 3% while indicating a decline in another city.
Frequently Asked Questions

Q4: Is the HPI the same for all market segments? A: No, the index can vary greatly depending on the type and segment of the market, such as single-family homes versus apartments.
