ASU professor Karl Guntermann has misread his tea leaves.  He believes Phoenix home prices are "stabilizing":

PHOENIX – According to an ASU business study, the housing market is on its way up.

Phoenix-area housing prices are declining at a slower rate than earlier this year, the study found.

This leads some to believe the worst is over in terms of the rate of decline in house prices — since prices seem to be stabilizing since February and March.

Although the housing market itself remains volatile, the median home price in metro Phoenix looks like it already hit rock bottom.

"It appears the worst is over… house prices appear to be stabilizing," says ASU professor Karl Guntermann.

Guntermann says Gilbert and Sun City showed the mildest drop, while the worst drop was in Glendale.

Home values have slid for 27 months in the valley — that’s the longest in valley history. "It’s hard to say if this is the true bottom or a temporary bottom," says Guntermann.

A "temporary bottom"?  Isn’t that called a "plateau", and not really a bottom at all? But I digress.  Here’s the chart that Guntermann is using to show that the market is "stabilizing":

It’s kind of hard to look at a price drop of nearly 30% year over year and say "Yep, it sure looks like things are stabilizing," even if that beats the drops of January and February.  It’s also only taking one aspect of the market into account. 

It is important to remember that "past performance is no guarantee of future results".  Consider the fact that around 68% of Phoenix homeowners are underwater, [Check out Reagor's headline in that link- I thought it was pretty funny.]and being underwater is one of the leading causes of foreclosures.  Also consider that according to FHFA, about 40% of foreclosures are due to loss of income, and while unemployment may not be as severe as in other places, the Valley economy is hurting.  [Check out the rise in unemployment here.] Then there’s this chart to consider, which I consider more significant than Guntermann’s: [Data from ARMLS]

 Before someone shoots off an email to remind me that "month’s supply" doesn’t really mean how many months a property is going to be on the market- I know it.  Face it though, when you look at the ratios [Which is after all what "month's supply" is.] the odds of you selling your $30,000 property in the Valley in the next month border on virtual certitude.  Your odds of selling your $3M dollar home in the Valley in the next month, or the next, or the next, aren’t that hot.

If a seller wants to increase their odds of selling a property, the easiest way to do that is to drop the price.  If a seller can’t or won’t, their lender probably will.  As long as there is a big supply of upper-end homes that need to slash their prices to sell, it is going to keep downward pressure on lower-end properties.

Sure, prices can’t drop at these rates forever- but that hardly means the worst is over.  There are too many factors stacked against "stabilization".
