The rich are the biggest defaulters of mortgages, they don't care about financial obligations to pay their loans

 No need for tears, but the well-off are losing their master suites and saying goodbye to their wine cellars.

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

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.

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 CoreLogic data suggests that many of the well-to-do are purposely dumping their financially draining properties, just as they would any sour investment.

“The rich are different: they are more ruthless,” said Sam Khater, CoreLogic’s senior economist.

The sheriff in Cook County, Ill., is increasingly in demand to evict foreclosed owners in the upscale suburbs to the north and west of Chicago — like Wilmette, La Grange and Glencoe. The occupants are always gone by the time a deputy gets there, a spokesman said, but just barely.

In Las Vegas, Ken Lowman, a longtime agent for luxury properties, said four of the 11 sales he brokered in June were distressed properties.

“I’ve never seen the wealthy hit like this before,” Mr. Lowman said. “They made their plans based on the best of all possible scenarios — that their incomes would continue to grow, that real estate would never drop. Not many had a plan B.”

The defaulting owners, he said, often remain as long as they can. “They’re in denial,” he said.

Here in Los Altos, where the median home price of $1.5 million makes it one of the most exclusive towns in the country, several houses scheduled for auction were still occupied this week. The people who answered the door were reluctant to explain their circumstances in any detail.

At one house, where the lender was owed $1.3 million, a woman said she and her husband had lost their jobs and were moving in with relatives. At another house, the family said they were renters. A third family, whose mortgage is $1.6 million, said they would be moving this weekend.

Lenders are fearful that many of the 11 million or so homeowners who owe more than their house is worth will walk away from them, especially if the real estate market begins to weaken again. The so-called strategic defaults have become a matter of intense debate in recent months.

The CoreLogic data suggests that the rich do not seem to have concerns about the civic good uppermost in their mind, especially when it comes to investment and second homes. Nor do they appear to be particularly worried about being sued by their lender or frozen out of future loans by Fannie Mae, possible consequences of default.

The delinquency rate on investment homes where the original mortgage was more than $1 million is now 23 percent. For cheaper investment homes, it is about 10 percent.

The rich and successful often come naturally to this sort of attitude, said Brent T. White, a law professor at the University of Arizona who has studied strategic defaults.

“They may be less susceptible to the shame and fear-mongering used by the government and the mortgage banking industry to keep underwater homeowners from acting in their financial best interest,” Mr. White said.

The CoreLogic data measures serious delinquencies, which means the borrower has missed at least three payments in a row. At that point, lenders traditionally file a notice of default and the house enters the official foreclosure process.

In Los Altos, Los Altos Hills and the most expensive neighborhood in adjoining Mountain View, defaults in the first five months of this year edged up to 16, from 15 in the same period in 2009 and four in 2008.

The East Bay suburb of Orinda had eight notices of default for million-dollar properties, up from five in the same period last year. On Nob Hill in San Francisco, there were four, up from one. The Marina neighborhood had four, up from two.

In the middle of a workday, one troubled homeowner here leaned over his laptop at the kitchen table, trying to maneuver his way out from under his debt and figure out the next big thing.

His five-bedroom house, drained of hundreds of thousands of dollars of equity over the last 13 years, is scheduled for auction July 20. Nine months ago, after his latest business (he has had several) failed in what he called “the global meltdown,” the man, a technology entrepreneur, said he quit making his $9,000 monthly payments.

“I’m going to be downsizing,” he said.

The man spoke on the condition of anonymity because, he said, he did not want his current problems to interfere with his coming reinvention. “I’m a businessman,” he explained. “I have to be upbeat.”
