ARM products are less risky for mortgage lenders, because if interest rates
rise during the term of the loan, the lender gets more interest income.
For example, if the
loan term depends on the value
of interest rate adjustments
during the
term of the
loan, to calculate the maximum
loan term, the creditor assumes that the interest rate
rises as rapidly as possible after consummation, taking into account the
terms of the legal obligation, including any applicable caps on interest rate adjustments and lifetime interest rate cap.
