A big hat tip to M, who’s been warning about the impending fall of the Scottsdale market for a couple of years now.  Others have not always concurred with him.  Take for example this quote from ASU professor and real estate analyst Anthony Sanders from April 2008:

Alt-A loans, which are low-documentation and no-documentation loans, are almost exclusively concentrated in Scottsdale. The wealthiest part of the Phoenix metro holds the highest concentration of no-documentation loans, which is not really a problem because if that market goes south, these homeowners will be better able to hold onto the mortgages without default given their higher average household income.

Here’s what happening with Scottsdale now: [Emphasis is M's]

The moral of the lesson here?  Rich people are not immune to market forces.  For example, many of the former wealthy in Scottsdale made their money in real estate.  They used wonky financing to get into a high end home thinking that prices would continue to rise.  Now incomes are down and home values are down.  It’s impossible to refi and difficult to sell.  There are years worth of expensive homes on the market. Jumbos are expensive and difficult to obtain. Walking is often the only option.

The Phoenix metropolitan area as well as the rest of the nation continues to be a tale of two markets.  Any sign of "stabilization" is only coming in the lower end- upper end real estate has a long way to fall.
