Basically, an ARM is a mortgage loan that has an interest rate that adjusts, or changes, usually once a year. The benefit of an ARM is that it generally gives you a lower interest rate initially. The risk is that the interest rate most likely will go up, which in turn will make your monthly payments rise.
