“U.S. home prices continued to rise in August 2023,” says Craig J.

The Composite now stands 2.6% above its year-ago level and 6.4% above its January level. Our 10- and 20-City Composites each also rose in August, and likewise currently exceed their year-ago and January levels.

“One measure of the strength of the housing market is the relationship of current prices to their historical levels. On that dimension, it’s worth noting that the National Composite, the 10-City Composite, and seven individual cities (Atlanta, Boston, Charlotte, Chicago, Detroit, Miami, and New York) stand at their all-time highs. Observing the breadth of price changes provides insight into another dimension of market health. On a seasonally adjusted basis, prices increased in 19 of 20 cities in August (and Cleveland only missed by a whisker); before seasonal adjustments, prices rose in 13 cities.
