JACKSONVILLE, Fla. – October 30, 2017 – Today, the Data and Analytics division of Black Knight, Inc. (NYSE: BKI) released its latest Home Price Index (HPI) report, based on August 2017 residential real estate transactions. The Black Knight HPI utilizes repeat sales data from the nation’s largest public records data set, as well as its market-leading, loan-level mortgage performance data, to produce one of the most complete and accurate measures of home prices available for both disclosure and non-disclosure states. Non-disclosure states do not include property sales price information as part of their publicly available county recorder data. Black Knight is able to obtain the sales price information for these states by combining and matching records across its unique data assets.
Each month the Black Knight HPI reports five price levels (quintiles), along with REO discount rates, for 18,000+ U.S. ZIP codes. Findings are available with or without seasonal adjustments, although all numbers that follow have not been seasonally adjusted.​

About the Black Knight Home Price Index

The Black Knight HPI is one of the most complete and accurate measures of home prices available, providing essential micro-level valuation data by covering nearly 90 percent of U.S. residential properties at the ZIP-code level. The Black Knight HPI provides the most timely updates possible, without the disruptive volatility of frequent historical revisions, for ZIP codes, cities, counties, states, the nation and statistical areas as defined by the White House Office of Management and Budget.

The Black Knight HPI utilizes repeat sales data from the nation's largest public records data set as well as its market-leading loan-level mortgage performance data to capture home price data from both disclosure and non-disclosure states.  Each month the Black Knight HPI reports five price levels (quintiles), along with REO discount rates for each of 18,000+ U.S. ZIP codes. This level of detail is provided for three property groupings in every ZIP code: i) all residential properties, ii) condominiums, and iii) single-family housing. Black Knight's HPI is available with or without seasonal adjustments (numbers cited above are not seasonally adjusted).
