As I quickly found out, American Home Mortgage had become one of the fastest-growing mortgage lenders in the country. One of its specialties was serving people just like me: borrowers with good credit scores who wanted to stretch their finances far beyond what our incomes could justify. In industry jargon, we were “Alt-A” customers, and we usually paid slightly higher rates for the privilege of concealing our financial weaknesses.

I thought I knew a lot about go-go mortgages. I had already written several articles about the explosive growth of liar’s loans, no-money-down loans, interest-only loans and other even more exotic mortgages. I had interviewed people with very modest incomes who had taken out big loans. Yet for all that, I was stunned at how much money people were willing to throw at me.

Bob called back the next morning. “Your credit scores are almost perfect,” he said happily. “Based on your income, you can qualify for a mortgage of about $500,000.”

What about my alimony and child-support obligations? No need to mention them. What would happen when they saw the automatic withholdings in my paycheck? No need to show them. If I wanted to buy a house, Bob figured, it was my job to decide whether I could afford it. His job was to make it happen.

“I am here to enable dreams,” he explained to me long afterward. Bob’s view was that if I’d been unemployed for seven years and didn’t have a dime to my name but I wanted a house, he wouldn’t question my prudence. “Who am I to tell you that you shouldn’t do what you want to do? I am here to sell money and to help you do what you want to do. At the end of the day, it’s your signature on the mortgage — not mine.”

You had to admire this muscular logic. My lenders weren’t assuming that I was an angel. They were betting that a default would be more painful to me than to them. If I wanted to take a risk, for whatever reason, they were not going to second-guess me. What mattered more than anything, Bob explained, was a person’s credit record. History seemed to show that the most important predictor of whether people defaulted on their mortgages was their “FICO” score (named after the Fair Isaac Corporation, which developed the main rating system). If you always paid your debts on time before, the theory went, you would probably keep paying on time in the future.

Bob’s original plan was to write two mortgages, one for 80 percent of the purchase price and a piggyback loan for 10 percent. I would kick in the final 10 percent, cashing out a chunk of New York Times stock — my last. If I had been a normal borrower, the whole deal would have sailed through at a low interest rate. My $120,000 base salary and my assets were easy to document. But given my actual income after alimony and child support, I couldn’t possibly have qualified for a standard mortgage. Bob’s plan was to write a “stated-income loan,” or “liar’s loan,” so that I wouldn’t have to give the game away by producing paychecks or tax returns.
