Key Insights At National Level

National TerraIndex™ HPI April 2023

The U.S. home values for combined single-family detached and single-family attached properties increased by 2.3% in July 2023 from a year ago. TerraIndex™ HPI reached the $346,000 mark at the end of July, a new record high.


On a month-over-month basis, non-seasonally adjusted (NSA) home values increased by 1.1% in July 2023. On a seasonally adjusted basis, monthly home values increased by 0.8%.


The 2.3% year-over-year increase, although relatively low, might accelerate in coming months due to contrasting market trends from last year. While home values experienced significant depreciation in Q3-Q4 2022, the recent monthly trend has been upward, potentially amplifying year-over-year numbers even if monthly growth cools down through the rest of 2023.

Why TerraIndex™ HPI

Our Home Price Index (HPI) is based on the proprietary Quantarium Valuation Model (QVM) value estimates for more than 100 million residential U.S. homes. QVM has been tested extensively in the last 5 years by some of the top third-party AVM testing agencies in the U.S. and has been consistently ranked at the top for both Accuracy and Hit Rate performance metrics. QVM was also recently approved by Fitch Ratings for Wall Street transactions. You can read the announcement here.

QVM re-computes the estimated values for the entire national footprint on a weekly basis, along with HPIs at various geography levels – from State, County, CBSA, down to Zip Code and Census Tract. Furthermore, the HPIs produced on any given date are based on proprietary valuation models which include over 90% of all sales transactions that will have been eventually reported through a four-week rolling period ending that date, taking advantage of Quantarium’s industry leading Data Services Platform (QDSP) to reduce the processing time lag to an absolute minimum. That allows Quantarium to provide the most current market insights, weeks faster than most other housing indices in the U.S. Learn more about TerraIndex™ HPI here.

The report for a given month is usually available on the second Wednesday of the following month, for example HPIs for the month of December 2022 were made available on Wednesday, January 11, 2023.
