Ruth Simon And James R. Hagerty:

23% of all mortgage borrowers in the US are underwater.

Decius:

Imagine if they all walked.

Kenneth R. Harney:

Don't feel guilty about it. Don't think you're doing something morally wrong.

Brent T. White:

Despite reports that homeowners are increasingly "walking away" from their mortgages, most homeowners continue to make their payments even when they are significantly underwater. This article suggests that most homeowners choose not to strategically default as a result of two emotional forces:

1) the desire to avoid the shame and guilt of foreclosure; and
2) exaggerated anxiety over foreclosure's perceived consequences.

Moreover, these emotional constraints are actively cultivated by the government and other social control agents in order to encourage homeowners to follow social and moral norms related to the honoring of financial obligations - and to ignore market and legal norms under which strategic default might be both viable and the wisest financial decision. Norms governing homeowner behavior stand in sharp contrast to norms governing lenders, who seek to maximize profits or minimize losses irrespective of concerns of morality or social responsibility. This norm asymmetry leads to distributional inequalities in which individual homeowners shoulder a disproportionate burden from the housing collapse.

Fiserv:

The Fiserv Case-Shiller Home Price Index forecasts that average single-family home prices will fall another 11 percent over the next twelve months, with declines expected in about 90 percent of the more than 350 metro areas tracked by Fiserv.

Mike Shedlock:

There is no good reason to assume home prices will rebound before 2012, and in fact prices might fall for much longer.

In the meantime, most Option-ARM holders are only making the minimum payment with negative amortization increasing monthly. When those loans do recast, anyone in their right mind will hand over the keys.
