WASHINGTON - House prices and sales during the April-June period portray a booming economy on the Pacific Coast, some cooling in the once red-hot Northeast, resurgence in the Midwest and a hint of a turnaround in the Southwest, a trade group said Thursday.

The National Association of Realtors said that three California metropolitan areas - Anaheim-Santa Ana, Los Angeles and San Francisco - posted the highest house-price appreciation rates in the country.

A 20.1 percent rise in prices in the second quarter of this year over same period in 1987 made the Anaheim-Santa Ana area the costliest housing market in the nation. Median house prices there were $204,000.
