FHFA House Price Index (HPI)

FHFA House Price Index (HPI) is a housing-market data concept used to track property prices, affordability, demand, or market cycles.

The FHFA House Price Index (HPI) is a critical measure of the average price changes of single-family houses across the United States. This index, compiled by the Federal Housing Finance Agency (FHFA), is based on data derived from mortgage loans held or guaranteed by Government-Sponsored Enterprises (GSEs) such as Fannie Mae and Freddie Mac. The HPI provides vital insights into housing market trends on a national, state, and metropolitan area level.

Data Sources

The FHFA HPI predominantly uses data from:

  • Mortgage loans purchased or securitized by Fannie Mae and Freddie Mac.

  • Repeat-sales method measuring changes in the price of the same property over time.

  • Pertinent property attributes and transaction dates from public records.

Formula

The HPI calculation uses the following repeat-sales regression technique:

$$ P_{t} = \beta_0 + \beta_1 \cdot Month_i + \beta_2 \cdot Property_j + \epsilon_{t} $$

Where:

  • \( P_t \) = House price at time t

  • \( \beta_0, \beta_1, \beta_2 \) = Coefficients

  • \( Month_i \) = Monthly indicator variable

  • \( Property_j \) = Property-specific variable

  • \( \epsilon_t \) = Error term

Purchase-Only Index

Includes only house price data for single-family properties that have been sold.

All Transactions Index

Incorporates purchase prices as well as appraisal values from refinancing.

Applications

  • Economic Analysis: Used by economists to track housing market health and identify trends over time.

  • Policy Making: Helps in formulating housing policies and regulatory measures.

  • Financial Markets: Aids investors by providing insights into real estate market performance.

  • Real Estate Valuation: Serves as a benchmarking tool for appraisers and valuation experts.

FHFA HPI vs. S&P/Case-Shiller Index

  • Coverage: The FHFA HPI includes data from all states and metropolitan areas, while the Case-Shiller covers select metropolitan areas.

  • Data Source: FHFA uses data from GSE mortgages; Case-Shiller includes a broader range of home sales.

  • Calculation Methodology: Both use repeat-sales regression techniques but apply different methodologies.
