The mortgage crisis long ago stopped being about subprime borrowers and moved into virtually all markets. A combination of people buying too much house, a collapse in prices, unemployment up and down the income scale and predatory lending has led to foreclosures throughout all walks of life. In fact, these days the mortgages most likely to fail have seven figures.

The housing bust that began among the working class in remote subdivisions and quickly progressed to the suburban middle class is striking the upper class in privileged enclaves like this one in Silicon Valley.

Whether it is their residence, a second home or a house bought as an investment, the rich have stopped paying the mortgage at a rate that greatly exceeds the rest of the population.

More than one in seven homeowners with loans in excess of a million dollars are seriously delinquent, according to data compiled for The New York Times by the real estate analytics firm CoreLogic.

By contrast, homeowners with less lavish housing are much more likely to keep writing checks to their lender. About one in 12 mortgages below the million-dollar mark is delinquent.

The common explanation here is that the rich are just dropping these homes like they would any investment, cutting their losses on an underwater, poorly performing security. But I don’t think that’s the whole story. Some rich people get unemployed, too. Some rich people live hand to mouth and get caught short when their mortgage rate recasts, too.

But nor would there be anything wrong with a strategic default if it was driving all these million-dollar mortgage walkaways. It’s called “fulfilling the terms of the contract.” And it’s telling that Fannie Mae and Freddie Mac, which service low-income homes, are the ones so exercised by strategic defaults that they’re increasing penalties for borrowers who engage in them, including making them ineligible for a Fannie or Freddie-backed loan for seven years after the foreclosure. Aside from government intervening in the market on the side of the banks, and the fact that it’s impossible to determine who is strategically defaulting and who can’t actually pay for a loan, Fannie and Freddie aren’t even attacking the source of the problem – wealthier people who view homes as investments. The working class still largely try to pay off their houses, according to this data.

One thing is clear – if strategic defaults are so attractive, it’s a sign that the market is broken, not the people making self-interested decisions. Loan modifications have done absolutely zilch to help struggling borrowers. The options on the table that could have provided relief, like cramdown or own-to-rent, didn’t get adopted. And so you have a situation where the rich buy and drop homes with relative impunity, but the most vulnerable borrowers, the ones pushed into loans they couldn’t afford, suffer the consequences.

UPDATE: Annie Lowrey agrees that the NYT article does a poor job of actually defining strategic defaults, and whether or not the rash of million-dollar foreclosures can be attributed to that.
