The face amount under mortgage protection term insurance decreases over time, consistent with the projected annual decreases in the outstanding balance of a mortgage loan. Mortgage protection policies are generally available to cover a range of mortgage repayment periods, e.g., 15, 20, 25 or 30 years. Although the face amount decreases over time, the premium is usually level in amount. Further, the premium payment period often is shorter than the maximum period of insurance coverage–for example, a 20-year mortgage protection insurance policy might require that level premiums be paid over the first 17 years.
