The drop in sales pushed the inventory of unsold homes up to 11.1 months, meaning it would take that long to exhaust the stock of unsold homes at the October sales pace.

Builders, who have been slashing production in an effort to get control of inventories, are being faced with soaring mortgage defaults which are dumping more unsold homes on an already glutted market.

The National Association of Home Builders reported last week that its survey of builder confidence fell to an all-time low of 9 in November, down from 14 last month. Index readings higher than 50 indicate positive sentiment about the market. But the trade group's index has drifted below 50 since May 2006 and below 20 since April.

The housing slump already has cost the country 3 million jobs in construction and related industries, and the home builders are urging Congress to help with increased support for the industry.

Tighter lending standards, rising defaults and fear about the housing market's future have sidelined buyers, an absence felt acutely by homebuilders such as Pulte Homes Inc. and Centex Corp.
