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.
