Reason In the Air

If you're paying too much for your optional ARM or interest-only loan, tune in to Airtalk with Larry Mantle (actually guest host Jon Beaupre), a gabfest on NPR Los Angeles affiliate KPCC 89.3 FM, which was kind enough to have me on a panel about the U.S. Comptroller's new guidelines on "predatory lending." Listen here.
Reason has chiseled interest in the expansion of financing in the past: James Twitchell took a look at how the longterm debt revolution put more money in everybody's pockets, while Mike Lynch said a prayer for the legal loan sharks of "payday lending."

downstater,
The lending business has changed dramatically in part due to automated underwriting systems. These are computer programs that take into account one's ability to repay debt, one's willingness to repay debt, and the ratio of the loan amount to the value of the property - really the same factors that came into play in the past. The difference now is that when a computer program is looking at current and historic income, amount of reserve funds, total indebtedness, history of debt repayment, and loan to value, the program looks at the total picture with an eye towards statistics of default far more effectively than a lowly human could. This accounts for borrwers who obtain a mortgage at 70% LTV, with 800 FICOs (credit scores), but a DTI (debt to income) or "back-end" ratio of 85%, when, typically, manual underwrites allow for a DTI of 45%, or slightly higher with compensating factors like a lot of reserve funds. Conventional financing with automated underwriting now also allows for some stated income and interest only loans.
The worlds of subprime, negative amortization, 100% financing (usually two loans, known as 80/20s), and no-doc loans are still based on manual underwriting for the most part, although these programs also use nominal automated underwriting, which mostly really a pre-qualification engine. The guidelines for these programs are also based on statistics, but much more emphasis is based on FICO scores, and the guidelines are much stricter - usually much less wriggle room.
High LTVs combined with no principal reduction or even negative amortization hit the market when housing prices were already rising. This was good in the sense that people could keep buying homes, but it also served to help keep driving prices up. Now we have all sorts of loans, the likes of which we have never seen, on the banks' books while home prices are stagnating or even falling in certain areas. Combine this with lenders subtly and overtly pressuring appraisers to juice up values for refinances, and even purchases, and my common sense tells me the banks could be in a lot of trouble. We don't have much history to look at for neg am loans or for so many loans on the books at such high LTVs. Lenders are already tightening up a lot of the standards for these non-conforming loans, which is a good thing, although it won't do anything to increase home values.
In short, the answer to your question is that lenders use more complicated statistical models. Some of the these models, however, have a longer history behind them.
