Qualifying rate
Adjustable-rate mortgages often employ a “qualifying fate” that differs from the “start rate.” The qualifying rate may be a pre-determined percentage of interest (i.e. “8 percent”), expressed as the “highest possible rate of interest at the beginning of the 2nd year”, based on the start rate (i.e. “start rate + 2 percent), expressed as the “Fully Indexed Accrual Rate” (“FIAR”) or another amount.
