ARM

ARM stands for ‘adjustable-rate mortgage,' which is a type of home loan that has a fixed interest rate for an initial period of time then after a certain point, the rate changes, which means it is no longer a fixed interest rate but rather the interest fluctuates during the life of the loan, based on the change or movement in the index rate or specific benchmark.
