A Home Price Index (HPI) is a measure used to track the relative level of home prices in a specific housing market at a given time. Instead of reflecting an average or median home price in dollar terms, the HPI indicates changes over time by being pegged to a starting value.
Definition
The Home Price Index quantifies the changes in home prices over periods by comparing the price of homes at different times. Essentially, it provides a straightforward, accurate measure that reflects market conditions, enduring comparisons across time frames.
Key Types of Home Price Indices
Case-Shiller/S&P Home Price Index
The Case-Shiller/S&P Home Price Index is one of the most renowned measures. It evaluates changes in the value of residential real estate in the United States, focusing on single-family homes. The methodology involves repeat-sales pricing, which examines the prices of homes sold multiple times to identify price change trends.
FHFA House Price Index (HPI)
Another significant Home Price Index is the FHFA House Price Index. Constructed and maintained by the Federal Housing Finance Agency, it uses data from mortgages bought or securitized by Fannie Mae and Freddie Mac, covering both accessible single-family homes and repeat-sales pricing.
Special Considerations
Calculation Methodologies
-
- The repeat-sales method involves tracking the prices of individual homes that have been sold multiple times, allowing a precise measurement of price changes for the same property.
-
- This method adjusts index measurements for various home characteristics, capturing quality changes within homes to isolate pure price movement.
Market Comparisons
Using Home Price Indices, analysts can compare different housing markets, studying the dynamics and price alterations over time. It enables an understanding of the broader economic environment and real estate trends.
Historical Context
The Home Price Index system was developed extensively in the late 20th century when more complex economic models required refined measures of price indices. Introduction and enhancement of computing technologies facilitated the widespread use and accuracy of these indices.
