The Real Estate Beginners Guide to Home Price Index (HPI) in 2026
Key Takeaways
- A Home Price Index (HPI) measures the change in residential home prices over time, not the price of any single house.
- The Federal Housing Finance Agency (FHFA) House Price Index is a weighted, repeat-sales index built from repeat sales or refinancings of single-family homes with mortgages purchased or securitized by Fannie Mae or Freddie Mac since January 1975.
- The FHFA index is released monthly and quarterly and covers all 50 states, over 400 American cities, and levels down to census tract.
- The two main methods are repeat sales, which compare the same property over time, and hedonic regression, which adjusts for property attributes.
- An HPI works best alongside other tools such as comparative market analyses, appraisals and local data.
The Home Price Index (HPI) is a statistic that tracks how much home prices in a region have risen or fallen relative to a starting period. The FHFA describes its index as a "weighted, repeat-sales index" that "measures average price changes in repeat sales or refinancings on the same properties."
How It Works, Step by Step
- An agency collects transaction data such as sales, mortgage records or appraisals.
- It applies a method: repeat sales (the same home sold twice) or hedonic regression (prices adjusted for features like size and age).
- It sets a base period equal to a fixed index level, for example 100.
- It publishes the index monthly or quarterly, often with seasonal adjustment, for a nation, state, metro area or smaller geography.
Worked Example
If a metro area's HPI moves from 200 to 210 over a year, home prices there rose about 5% (210 divided by 200). It does not mean a particular $400,000 house is now worth $420,000. The index describes the market overall. The numbers are illustrative.
Why It Matters to Investors and Agents
Investors use the HPI to see how fast a market is appreciating before they buy and to compare metro areas. Agents use it to explain trends to sellers and buyers. Because it uses the same properties over time, it avoids the distortion a median sale price can have when the mix of homes sold changes.
HPI Compared With Other Price Measures
Measure | What it tells you | Level |
|---|---|---|
Home Price Index (HPI) | Percentage change in prices over time, based on repeat sales or adjusted attributes | Market or region |
Median sale price | The middle price of homes sold in a period, affected by which homes happen to sell | Market or region |
Comparative Market Analysis (CMA) | An agent's estimate of one home's value from similar nearby sales | Single property |
Appraisal | A professional's opinion of one property's market value | Single property |

More Frequently Asked Questions
Is the Case-Shiller index the same as the FHFA HPI?
No. They are separate indexes from different publishers with different data and methods, so their numbers differ. Check which index a source is quoting.
Does the HPI tell me what my house is worth?
No. The HPI shows how prices in an area have changed. An appraisal or comparative market analysis estimates the value of a specific home.
