International credit ratings agency Fitch Ratings improved its outlook on the U.S. housing market in its recent “Chalk Line” report, but that’s not saying much considering it still expects housing starts and new home sales to continue to plunge downward through the end of the year.

“During the first 12-15 months off the bottom, the housing recovery may appear jaw-toothed as substantial foreclosures now in the pipeline surface as distressed sales, while meaningful new foreclosures arise from Alt-A and option adjustable-rate mortgage resets,” wrote managing director and lead U.S. homebuilding analyst Bob Curran.

The new forecast includes a 36.7 percent decrease in total housing starts in 2009, up from a previous prediction of 43.3 percent. The new projection calls for a 21 percent decline in new home sales, up from the earlier forecast of 30 percent. And existing home sales are now expected to move up 1.1 percent this year to almost 5 million, a change from Fitch’s last prediction of flat sales.

Why the more “upbeat” outlook? Fitch says it took into consideration increased affordability, a slowing of builder cancellation rates, shrunken builder inventories, an uptick in consumer confidence and an increased demand for new homes from those who have been sitting on the sidelines.

Why are the numbers still trending downward though? According to Fitch there is still a great risk of a new wave of foreclosures on the way, home prices continue to decline, and the first-time homebuyers tax credit that has artificially inflated sales for the past two quarters is due to expire in December.

“There is also a negative psychology that remains relatively pervasive. For many, the expectation or fear is that home prices are vulnerable to further declines and buying now might be a mistake,” Curran wrote. “This psychology applies to all types of buyers but especially applies to trade-up and second-home buyers.”

So, we may be in for many more ups and downs across the market for at least the foreseeable future!
