Does an cap rate on a ARM loan protect borrower?
The interest rate caps on an ARM loan, or adjustable rate
mortgage, are designed to protect the borrower from "rate shock" or
sudden extreme changes in their interest rate, which also cause
spikes (or drops) in their monthly payment. Most ARM loans have
several different kinds of rate limits, including the first rate
change limits, subsequent rate change limits and the life of loan
change limits, also called the rate ceiling or rate floor.
