If you've become comfortable with the current state of the housing market ... don't. Economists at Goldman Sachs (NYSE: GS) and Bank of America's Merrill Lynch (NYSE: BAC) say there's still plenty of risk in the housing market.

Alec Phillips, the head of Goldman's Washington office, said, "The risk of renewed home price declines remains significant." His "working assumption" is a drop of between 5% and 10% by the middle of next year.

Mortgage applications fell almost 25% last week with new loan applications for home purchases hitting an eight-year low, according to the Mortgage Bankers Association. People continue to sit on the sidelines, waiting for prices to drop. Who wants to buy a home today if the price for that home might be lower soon after the deal closes?

Adding to that wait-and-see attitude are some major incentives that could be part of the stimulus package making its way through Congress. The biggest incentive of them all is a Senate provision that would give all home buyers a $15,000 tax credit. Who wouldn't wait to see if that provision survives the House/Senate negotiations?

The epicenter of everything -- the credit crisis, financial crisis, economic crisis and crisis of confidence -- is housing.

Not just bad mortgages, but a continuing fall in housing prices -- already down 20% with another 15%-20% to go.

Yup, it is not close to being over. Home sales continue to fall, inventories are equal to more than a year of sales, and the vast majority of new mortgages being applied for as interest rates fall are for refinancings.
