Almost half of single-family houses in the New York and Washington metropolitan areas are losing value, a sign that buyers' tolerance for high prices in many large U.S. cities may be reaching a limit.
The values of 45 percent of houses in both the Washington and New York areas slumped by at least 2 percent in June from a year earlier, according to a new index created by Allan Weiss, co-founder of the Case-Shiller home price indexes. In June 2014, only 15 percent of Washington residences dropped in value, while 20 percent fell in New York. Because the index is of only single-family homes, it doesn't include Manhattan. More properties also were in decline in Los Angeles, Chicago, Phoenix and Miami.
