When the mess from the housing collapse finally clears, we will see that mortgage fraud was one of the main drivers behind rising prices. Easy credit made it easy to steal,

ATLANTA -- Skyrocketing foreclosures are a testament to how easy it was to borrow from mortgage lenders in recent years.

It may also have been easy to steal from them, to judge from a multimillion-dollar fraud scheme that federal prosecutors unraveled here in Atlanta. The criminals obtained $6.8 million in mortgages from Bear Stearns Cos., including a $1.8 million mortgage to Calvin Wright, a New Yorker who told the investment bank that he and his wife earned more than $50,000 a month as the top officers of a marketing firm. Mr. Wright submitted statements showing assets of $3 million, a federal indictment alleged.

In fact, Mr. Wright was a phone technician earning only $105,000 a year, with assets of only $35,000, and his wife was a homemaker. The palm-tree-lined mansion they purchased with Bear Stearns's $1.8 million recently sold out of foreclosure for just $1.1 million. Bear Stearns, meanwhile, posted the first quarterly loss in its 84-year history as it wrote down $1.9 billion of mortgage assets yesterday. (See related article.)

Fraud goes a long way toward explaining why mortgage defaults and foreclosures are rocking financial institutions, Wall Street and the economy. The Federal Bureau of Investigation says the share of its white-collar agents and analysts devoted to prosecuting mortgage fraud has risen to 28%, up from 7% in 2003. Suspicious Activity Reports, which many lenders are required to file with the Treasury Department's Financial Crimes Enforcement Network when they suspect fraud, shot up nearly 700% between 2000 and 2006.

In 2006, losses from fraud could total a record $4.5 billion, a 100% increase from the previous year, says Arthur Prieston, chairman of the Prieston Group, which provides lenders with mortgage-fraud insurance and training. The surge ranges from one-off cases of fudging and fibbing to organized criminal rings. The FBI says its active mortgage-fraud cases have increased to 1,210 this year from 436 in 2003. In some regions, fraud may account for half of all foreclosures. "We've created a culture where a great many people know how to take advantage of the system," says Mr. Prieston.
