The latest S&P Case/Shiller report showed that the housing market debacle is far from over and is getting worse.

Based on the November home price index in the S&P Case/Shiller Report, the 10-city home price index was down 8.4 percent in November compared to last year’s while the 20-city index also fell 7.7 percent.

The Case/Shiller report is considered to be the most accurate snapshot of prices of homes. It compares same-home sale prices.

The largest year-over-year decline on record was 6.3 percent in April 1991. The November report marked the 11th consecutive month of negative returns for the index, and twenty-four months of decelerating returns.

The worst hit market of the 20 metro areas covered was Miami, where the median home fell a whopping 15.1 percent in value. San Diego prices also fell steeply, down 13.4 percent. Las Vegas was off 13.2 percent and Detroit by 13 percent.

Three cities did emerge with higher prices compared with 12 months ago: Prices rose 2.9 percent in Charlotte, N.C., 1.8 percent in Seattle and 1.3 percent in Portland, Ore. But even these markets have turned down over the last three months. Indeed, every city in the index recorded at least three consecutive months of falling prices through November.

The three biggest U.S. cities also recorded year-over-year declines; New York was down 4.8 percent, Los Angeles 11.9 percent and Chicago 3.9 percent. The losses in Los Angeles accelerated in November; that city recorded the largest month-over-month drop of any index city, 3.6 percent.

Tuesday's report came in the wake of many other surveys indicating that the housing market is getting worse. Foreclosure filings and the risks of future foreclosures were both up sharply; the number of new homes sold plunged more steeply than any year on record; and the pace of existing home sales fell to their lowest level in 27 years.
