The region’s housing market slowed in June, showing signs that Washington’s booming home prices are now exposed to the same economic strains the rest of the country has weathered. In addition, new data shows that the slowdown began earlier this summer than originally thought, according to a new S&P/Case-Shiller Home Price Indices report.

Home prices in June fell 1.2 percent from a year earlier, the report said. Prices for May were also adjusted to show a 1.7 percent decrease in area home values after more sales were reported. May home sales originally showed a 1.3 percent uptick.
