What is Adjustable Rate Mortgage - ARM Mortgage

ARM or Adjustable Rate Mortgage is a good option for those who plan to own your home for a few years only or if you are expecting an increased earning or if your existing fixed rate mortgage is too high.

There are 4 components in Adjustable Rate Mortgage:

1. Index
2. Margin
3. Interest Rate Cap Structure
4. Initial Interest Rate Period

After the expiry of the initial IR, the new IR is calculated by an addition of margin to the index. When you apply for the mortgage loan, your lender is supposed to disclose the margin. This, however, may vary from one lender to another. So, make sure you ask more than 2-3 lenders before you can settle. Your interest rate is directly proportional to your index figure. With a change in the index figure, there will also be a change in your interest rate.

The IR cap is designed to provide protection from huge rate swings in interest. Caps can be of 2 types:

1. Annual
2. Life-of-the-loan

Any change in this will be restricted by the annual cap. Whereas, the life-of-the-loan cap will limit the maximum and minimum rate of interest and as a mortgage loan you can pay for as long as your mortgage exists.
