WASHINGTON - U.S. home sales slid 3.6 percent in December, as rising prices and a declining number of available properties stifled purchases. The National Association of Realtors said that sales of existing homes fell last month to a seasonally adjusted annual rate of 5.57 million units. Despite the monthly setback, sales totaled 5.51 million in 2017. That was the highest level since 2006, yet it marked a slight 1.1 percent gain from 2016 as the months' supply of properties on the market fell to the lowest level ever recorded by the real estate group. The strengthening U.S. economy helped to lift home sales last year, but homeowners are choosing not to list their properties despite the rising prices and relatively low mortgage rates.
