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 usually remains the same. Further, the premium payment period is often shorter than the maximum period of insurance coverage — for example: a 20-year mortgage protection policy might require level premiums be paid over the first 17 years.
