The nation’s housing slump deepened in June as sales of previously occupied homes slowed to their slowest pace since December, hampered by elevated mortgage rates and record-high prices.

Sales of previously occupied U.S. homes fell 5.4% last month from May to a seasonally adjusted annual rate of 3.89 million, the fourth consecutive month of declines, the National Association of Realtors said Tuesday.

Existing home sales were also down 5.4% compared with June of last year. The latest sales came in below the 3.99 million annual pace economists were expecting, according to FactSet.

Despite the pullback in sales, home prices climbed compared with a year earlier for the 12th month in a row. The national median sales price rose 4.1% from a year earlier to $426,900, an all-time high with records going back to 1999.

Strong quarter at GM overshadowed by potential headwinds

U.S. customers who bought a new General Motors vehicle last quarter paid an average of just under $49,900, a price that helped push the company’s net income 15% above a year ago.

And GM Chief Financial Officer Paul Jacobson said he doesn’t see his company cutting prices very much, despite industry analysts’ predictions of growing U.S. new-vehicle inventories and bigger discounts.

The Detroit automaker made $2.92 billion from April through June and posted revenue of $47.97 billion. Excluding one-time items, the company made $3.06 per share, 35 cents above Wall Street estimates, according to data provider FactSet, and revenue was better than expected as well.
