The pre-seasonally adjusted U.S. National Index saw slight upward trends in May, posting gains of 0.4%. The 10-City Composite and 20-City Composite Indices both reported gains of 0.4%.

After seasonal adjustment, the U.S. National Index posted a decrease of -0.3%. Both the 10-City Composite and the 20-City Composite Indices saw a -0.3% decrease, as well.

“May’s data continued the year’s slow unwind of price momentum, with annual gains narrowing for a fourth consecutive month,” said Nicholas Godec, CFA, CAIA, CIPM, Head of Fixed Income Tradables & Commodities at S&P Dow Jones Indices. “National home prices were just 2.3% higher than a year ago, the smallest increase since July 2023, and nearly all of that gain occurred in the most recent six months. The spring market lifted prices modestly, but not enough to suggest sustained acceleration."
