The house that set off the national furor over faulty foreclosures is blue-gray and weathered. The porch is piled with furniture and knickknacks awaiting the next yard sale. In the driveway is a busted pickup truck. No one who lives there is going anywhere anytime soon. Nicolle Bradbury bought this house seven years ago for $75,000, a major step up from the trailer she had been living in with her family. But she lost her job and the $474 monthly mortgage payment became difficult, then impossible. It should have been a routine foreclosure, with Bradbury joining the anonymous millions quietly dispossessed since the recession began. But she was wise enough to contact a nonprofit group, Pine Tree Legal Assistance, where for once in her 38 years, she caught a break. Her file was pulled, more or less at random, by Thomas A. Cox, a retired lawyer who volunteers at Pine Tree. He happened to know something about foreclosures because when he worked for a bank he did them all the time. Twenty years later, he had switched sides and, he says, was trying to make amends. Suddenly, there is a frenzy over foreclosures. Every state attorney general is participating in an investigation into the flawed paperwork and questionable methods behind many of them. A Senate hearing is scheduled, and federal inquiries have begun. The housing market, which runs on foreclosure sales, is in turmoil. Bank stocks fell Thursday as analysts tried to gauge the impact on lenders' bottom lines. All of this is largely because Cox realized almost immediately that Bradbury's foreclosure file did not look right. The documents from the lender, GMAC Mortgage, were approved by an employee whose title was 'limited signing officer,' an indication to the lawyer that his knowledge of the case was effectively nonexistent. Cox eventually won the right to depose the employee, who casually acknowledged that he had prepared 10,000 foreclosures a month for GMAC and that contrary to his sworn statements, they had not been reviewed by him or anyone else. GMAC, the country's fourth-largest mortgage lender, called this omission a technicality but was forced last month to halt foreclosures in the 23 states, including Maine, where they must be approved by a court. Bank of America, JPMorgan Chase and other lenders who used robo-signers -- the term caught on instantly -- have enacted their own freezes. The tragedy of foreclosure is that some homeowners may be able to stay where they are if their lenders are more interested in modification than eviction. Without a job, Bradbury is not one of them. Her family, including her 14-year-old daughter and 16-year-old son, lives on welfare and food stamps. 'A lot of people say we just want a free ride,' Bradbury said. 'That's not it. I've worked since I was 14. I'm not lazy. I'm just trying to keep us together. If we lost the house, my family would have to break up.'
