House Price Index: A Detailed Explanation
The House Price Index, developed by the Federal Housing Finance Agency (FHFA), measures the movement of single-family house prices in the U.S. It provides a broad understanding of the housing market's current state and potential future trends.
By monitoring the HPI, first-time home buyers can determine whether it's a good time to buy a home. The index helps identify whether the market favors buyers or sellers based on historical price trends and current values. The HPI is a useful tool for comparing current and past prices.
The House Price Index is also used to establish conforming mortgage loan limits, which are based on the annual Q3 change in HPI.

How is the House Price Index Calculated?
The FHFA's House Price Index is calculated using a weighted repeat-sales method. This method analyzes mortgage transaction data from Fannie Mae and Freddie Mac to track home value changes over time, focusing on properties with at least two successive sales. The index measures the price change of the same property over different periods, providing a realistic and consistent view of price movements in the housing market.
