What is an Adjustable-Rate Mortgage?

An adjustable rate mortgage (ARM) is a mortgage loan with a fixed note and interest rate that is adjusted periodically based on an index based on a cost of funds for the lender to borrow money from the credit markets. The loan is typically offered at the lender’s standard variable rate/ base rate. There might be an index the rate is tied to or not and could be adjusted at the lenders discretion.

This type of loan can save you thousands on your monthly payments and is great if you know your planning to move in 5, 7 or 10 years.

How it Works

  • Currently, there are 3 different terms for adjustable-rate mortgages. There is a 5-year fixed, 7-year fixed and 10-year fixed mortgage loans. Once the term is expired, interest rates can adjust up or down depending on the index it is based on.
  • Typically, there is a cap of 5% for any rate adjustments above your initial rate.
  • You can be eligible for no prepayment penalties.

Negative amortization loans typically result in borrowers owing more than their principal loan borrowed.

The periodic cap limits how much your rate can change in a specific period such as a 1-year period. A lifetime cap is the cap at which the ARM rate can change over the period. Let’s assume you have a periodic cap of 2% per year. The interest rates rise by 3% in one year for example, but if the cap is 2% then the cap is 2%. Your protected by the cap and not subject to increase in the market and limited to the cap of 2% increase.
