WASHINGTON (AP) — U.S. home prices rose in January after three months of declines. A tight supply of homes might have helped boost prices and offset sales slowed by cold weather.

Real estate data provider CoreLogic says prices rose 0.9 percent in January after dipping 0.1 percent in December. Over the past 12 months, home prices have risen 12 percent, the biggest year-over-year gain in more than eight years.
