The cargo ships of new programs being shipped out of Washington each week alone can keep one’s head spinning. Like the weather, it is nearly impossible to get an accurate reading let alone glean reliable numbers on which to base plans.

So, it is no surprise that conflicting signals are coming from competing economic brain trusts. This week’s examples come from Duetsche Bank researchers and HIS Global Insight.

Deutche Bank researchers say home prices will drop another 10 to 12 percent from current levels. The securitization arm of the investment bank represent that these projections are the first forecast expanded to include more factors that impact home prices overall as well as including peak-to-trough and peak-to-peak, according to housingwire.com.

There is a pending supply of an estimated 1.1 million so-called shadow inventory of real estate owned by banks and mortgage companies plus real estate at least 90 days delinquent not factored included in official numbers.

On the flip side, HIS Global Insight’s quarterly housing valuation survey showed prices were up 0.2 percent from the Q2 with California leading with a 2.1 percent rise in home prices.

The survey, which covered 330 metropolitan areas, showed prices rose in 169 markets and fell in 161. For the first time since the survey started in 2005, there were no metro areas deemed to b “extremely” overvalued.

“For the nation as a whole, the housing market is now slightly undervalued, 8.6 percent when weighted by market value and 10.1 percent when weighted by housing units,” HIS Global Insight said.

The Federal Housing Finance Agency shows housing prices rose 0.9 percent Y/Y in the July-September period. That was the first advance since Q2 of 2007 when the housing market slide began.
