Sales of previously occupied U.S. homes slowed last month as rising prices and a dearth of homes for sale kept some would-be buyers on the sidelines. The National Association of Realtors said Monday that existing homes sales in February fell 6.6% from January to a seasonally-adjusted rate of 6.22 million annualized units. Sales were up 9.1% from February last year. Home prices continued to climb, driven by sales of higher-end homes. The report showed that the U.S. median home price was $313,000 in February, up 15.8% from a year earlier. At the end of February, the inventory of unsold homes stood at just 1.03 million homes for sale, down 29.5% from a year earlier.
