Freddie Mac CEO: "The housing market is far from stabilizing"

Freddie Mac's CEO predicts an 18-20% housing decline, peak to trough. From CNBC:

U.S. house prices will fall by as much as 20 percent nationally and the current mortgage finance crisis is about half-way through, the chief of major mortgage financier Freddie Mac said Wednesday.

"Previously, we said house prices would fall at least 15 percent nationally, peak to trough. Today's challenging economic environment suggests that the housing market is far from stabilizing," Richard Syron, the chairman and CEO of Freddie Mac, told investors in a conference call held to discuss the company's earnings.

"As a result, we now believe that national home prices will fall 18 to 20 percent peak to trough. ... The long and short of it is that we now think that we are half-way through the overall peak-to-trough decline."
