Here’s a chart to go along with yesterday’s excellent commentary by Diana Olick of CNBC on the disturbing trend in back-end debt-to-income ratios for so-called “permanent” mortgage modifications and how they might factor into rising default rates, part of the government’s Home Affordable Modification Program otherwise known as HAMP.

Note that front-end debt service (i.e., PITI, etc.) stays fixed at 31 percent (per program rules) while back-end debt service (i.e., all debt) has no upper bound, now at 64.1 percent. Yes, that leaves borrowers with 35.9 percent of their income to pay for taxes, utilities, insurance, food, gasoline, clothing, save for retirement, and have some fun from time to time.

What was funny about preparing the above graphic was that the source had to be cited. In doing so, it became quite clear that the government probably has the wrong name for their website – while the name may say “financial stability”, the figures in the chart say something quite different – perhaps “financialmadness.gov” would be better.
