Good question today: How many home mortgages in the Austin area are underwater (i.e. people owe more than the house is worth)?
The standard figures, from an organization called American CoreLogic, has come up with a report that is cited by several newspapers and business newspapers.
It includes the top 50 metropolitan areas by underwater status.
I would have put the report up in PDF form, but you must register for free beforehand, and I don't want to step on anybody's toes over at American CoreLogic.
