U.S. Home Prices have Sharpest Drop since 1987

NEW YORK (AP) November 27, 2007 — U.S. home prices fell 4.5 percent in the third quarter from a year earlier, the sharpest drop since Standard & Poor’s began its nationwide housing index in 1987 and another sign that the housing slump is far from over, the research group said Tuesday.

The index also showed that prices fell 1.7 percent from the previous three-month period, the largest quarter-to-quarter decline in the index’s history.

The S&P/Case-Schiller quarterly index tracks prices of existing single-family homes across the nation compared with a year earlier.

A separate index that covers 20 U.S. metropolitan areas dropped 4.9 percent in September from a year earlier, with 15 metro areas posting declines. Only five metro areas — Atlanta, Charlotte, N.C., Dallas, Portland, Ore., and Seattle — showed an increase in prices, but S&P noted that the pace of the rise is decelerating.

Tampa and Miami led the index with the lowest year-over-year declines at 11.1 percent and 10 percent, respectively. It also showed drops in San Diego of 9.6 percent; Detroit, 9.6 percent; Las Vegas, 9 percent; Phoenix, 8.8 percent; and Los Angeles, 7 percent.

The S&P’s 10-area index decreased 5.5 percent in September from the previous year.

Last week, the National Association of Realtors said that sales of existing homes fell in 46 states in the third quarter. However, the trade group said home prices rose in 93 of the 150 metropolitan areas surveyed.

Foreclosures Will Sap U.S. Cities

Rising foreclosures will lead to billions of dollars in lost economic activity next year in major U.S. cities, but homeowners and financial institutions have the ability to work together to contain the effects, said a report released Tuesday.

The report was compiled for a conference of U.S. mayors in Detroit. The mayors hope to create policy recommendations to help address the nation's housing crisis.

Prepared by forecasting and consulting firm Global Insight, the report said weak residential investment, lower spending and income in the construction industry and curtailed consumer spending because of falling home values will combine to hold back the nation's economic activity.

"The wave of foreclosures that has rippled across the U.S. has already battered some of our largest financial institutions, created ghost towns of once vibrant neighborhoods — and it's not over yet," the report said.

The biggest losses in economic activity are projected for some of the nation's largest metropolitan areas. New York is expected to lose $10.4 billion in economic activity in 2008, followed by Los Angeles at $8.3 billion, Dallas and Washington at $4 billion each, and Chicago at $3.9 billion.

The report estimates U.S. gross domestic product growth in 2008 will be 1.9 percent, coming in about $166 billion — or one percentage point - lower as a result of mortgage problems. GDP is the value of goods and services produced and is considered the best barometer of the country's economic fitness.

The report also projects property values will decline by $1.2 trillion in 2008, due in part to the foreclosure crisis, with drops in home prices across the U.S. averaging 7 percent. And it said the loss of property, sales and real estate transfer taxes will hurt local and state governments.

But homeowners, banks, holders of mortgage-backed securities and loan servicers can work together to ease the economic effects, the report said. Agreeing to new payment terms on some loans, for example, could make the difference between a family keeping a home and losing it in foreclosure.

"Such actions will help to lessen the number of foreclosures thereby avoiding the further negative effects on local housing markets and on the broader economy," according to the report, titled "The Mortgage Crisis: Economic and Fiscal Implications for Metro Areas."

The Detroit conference will address the state of the mortgage industry, ways homeowners can avoid foreclosure, and strategies to keep foreclosed properties from dragging down the quality of life in neighborhoods.

The mayors' recommendations are to be presented at a conference in January.
