Provided by Dow Jones By Nicole Friedman Sales of previously owned homes slipped in November from a month earlier, as the supply of homes for sale fell to a new low. Existing-home sales fell 2.5% in November from October to a seasonally adjusted annual rate of 6.69 million, the National Association of Realtors said Tuesday. The November sales marked a 25.8% increase from a year earlier. Economists surveyed by The Wall Street Journal expected a 2.2% monthly decline in sales of previously owned homes, which make up most of the housing market. "Without a doubt, there are too many buyers in relation to the sellers," said Lawrence Yun, NAR's chief economist. "That is probably the main driver as to why the sales declined."
