You expect students to struggle with unfamiliar concepts when learning them for the first time. But when teachers make simple mistakes about important financial matters such as taking out a mortgage, you can see that perfectly intelligent adults have a lot to learn about money, especially when it comes to the emotional process of buying a home in a tough real estate market.
One Fool's wife works as a math teacher. On one occasion, she was showing her colleagues how to use their fancy financial calculators to do time-value of money calculations. A few of the enterprising batch started to enter the terms of their mortgages. One woman in particular looked mortified, eyes like saucers, jaw dropping onto the desk, that kind of thing.
Turns out, she and her new husband had recently taken out an adjustable-rate mortgage, and she was shocked to see what a change in the interest rate might do. But it was worse than that. It was an ARM that actually amortizes negatively. Don't know what that means? Here's a refresher.
The way not to pay
With most home mortgages, the payment you make each month goes toward two distinct destinations. One bit pays the interest you owe, and the other pays off a bit of the original principal on the loan. As you continue to make your payments, the outstanding principal on the loan shrinks bit by bit -- and the amount of principal you pay off each month grows. That's how you can pay off your home by the end of the loan's term.
In recent years, a large percentage of homebuyers -- up to 50% in some areas, according to various reports -- took advantage of interest-only loans. We've already discussed the risks of these, both for the consumer and for financial institutions such as Countrywide Financial
But these negatively amortizing loans are even scarier. Like a credit card, the minimum payment every month isn't enough to cover the interest accrued. The difference is tacked onto the amount you owe, and as a result, the principal on the loan continues to rise. In other words, despite the fact that you're making the required payments, the real amount you paid for that house continues to swell. At least until it reaches 110-125% of the original purchase price, at which point the loan converts, and you have to start paying all of the interest plus a portion of the principal each month.
The hard truth
A few figures from one bank's online calculator ought to help illustrate just how quickly you can get yourself into trouble with a loan like this. Imagine you buy a run-of-the-mill home in the Washington, D.C., area, borrowing $500,000. Assume that you make your minimum payments at the teaser rate, until the principal reaches $550,000. (That will happen in less than three years.) At that point, the loan is amortized over 30 years at a new, higher interest rate (let's say 7.25%). Suddenly, your tasty-looking $1,608 per month jumps to $3,752.
Now you probably understand why this young woman looked so shocked. You may be thinking, "How could you not know the payment terms of the largest purchase you'll ever make?" But consider how such "products" have been marketed.
These loans typically come with 1% teaser rates and are sold with happy-sounding names like "option ARM," "Cash Flow Mortgage, or "Pick-a-Payment" plans. As you might guess, they're marketed under the guise of "affordability." But that's a pretty slippery word to use when the buyers may end up starting their homeowner experience by beginning their loan paybacks at a price 10% to 25% higher than what they thought they were paying for the house.
Worse yet, as interest rates have gone up, the people holding these loans, making minimum contributions, have started to see their payments suddenly jump by huge amounts -- perhaps even double. For people already stretched thin by their mortgage payments -- my Realtor tells me that paying 40% of gross monthly income is not unusual out here -- this is spelling disaster.
The Foolish bottom line
The easiest way to avoid this kind of financial death trap is to buy no more home than you can afford, and perhaps even be willing to admit that you can't afford a home. Despite what the commercials with the soft focus and the puppy dogs and the picket fences want you to think, there's no shame in renting, especially if home prices still haven't fallen far enough for you to afford the house you want. But if you're determined to get out there and pay any price to get your dream house, at least stick with a more traditional ARM, or even an old-fashioned fixed-rate mortgage. Fortune -- even ill fortune -- favors the prepared.
