Mortgage borrowers have received a call to arms lately -- or rather, a call to ARMs, or adjustable-rate mortgages. Unfortunately, for many people, this increasingly popular variety of loan just isn't the best choice.
Nuts and bolts
Mortgages come in two main flavors, bearing either fixed or adjustable rates. The interest you pay on a fixed-rate mortgage stays the same for the life of the loan. If you lock in a low rate, you're set for decades, and you'll always know how much to pay each month.
ARMs fix their rates for an initial period, but then begin to adjust the interest they charge according to prevailing rates. A cap usually limits how much rates can rise with each increase, but over time, interest can grow substantially, leaving borrowers on the hook for ever-steeper payments.

If you're in the market for a mortgage, deliberate carefully between fixed-rate and adjustable-rate loans. The ARM can bite you if rates rise -- and after lingering near historic lows for years, rates most certainly will increase. Still, low rates may persist for several more years, and if you don't plan to stay in your home much longer than that, an ARM can make good sense.
