"Option ARM" loans - a disaster in the making

Comments from John C. Dugan, Controller of the Currency, on exotic mortgages and the housing market.. Bottom line is the government is going to try to get some control of this runaway freight train heading towards the abiss....

The fundamental problem with payment option ARMs, other than the growing principal balance due to negative amortization, is payment shock. A traditional 30-year fixed-rate mortgage requires the borrower to amortize the principal balance through equal payments over the 30-year life of the loan. In contrast, a typical payment-option ARM is a 30-year mortgage that permits five years of negative amortization by allowing a borrower to make very low minimum monthly payments during that period. Beginning in the sixth year, the borrower must begin paying the full amount of interest accruing each month, and must also begin amortizing the increased principal over the remaining 25-year life of the loan. The combination of these factors can produce sharply increased payments in year six. For example, a typical payment-option mortgage of $360,000 at 6 percent can produce a monthly payment increase of nearly 50 percent in that year, assuming no change in interest rates. If rates rise to just 8 percent, the payment increase when amortization begins would nearly double.

To the extent that they are planning for such contingencies, many payment-option-ARM borrowers calculate that they will be able to sell their property or refinance the mortgage by year six. But if real estate prices decline – and there already is evidence of softening in some markets – these borrowers could face the bleak prospect of loan balances that exceed the value of the underlying properties. In that case, selling the property or refinancing the loan would not be a viable escape valve for avoiding huge payment shocks.
