An internal JPMorgan Chase memo entitled Zippy Cheats & Tricks" offers a peek into just the sort of dubious lending tactics that underpinned the U.S. housing market's deepening downward spiral. The memo outlines step-by-step instructions on how to beef up mortgage applicants' stated incomes in order to help them qualify for home loans. They read as follows: "1. Make sure you input all income in base income. DO NOT break it down by overtime, commissions or bonus. 2. If your borrower is getting a gift, add it to a bank account along with the rest of the assets. Be sure to remove any mention of gift funds. 3. If you do not get (the desired results), try resubmitting with slightly higher income. Inch it up $500 to see if you can get the findings you want. Do the same for assets." In the context of a broader housing debacle, the memo [provides] some clues into just what lengths bankers went to [to] push loans through the system. Over the past six months, rising defaults on home loans have not only battered the mortgage sector, threatening recession, but also sent the banking industry into a tailspin. Many large banks repackaged mortgages and held them on their balance sheets as complex derivatives securities, essentially bonds backed by other types of loans. The conclusion of the JPMorgan memo, written in bright purple letters, certainly hints at a credit system gone awry: "It's super easy! Give it a try!" it reads. "If you get stuck, call me ... I am happy to help!"
