Adjustable Rate Mortgage Loans – Understanding the Basics

While an ARM has many benefits, there are other considerations to look at.

Adjustable rate mortgages (ARMs), developed when mortgage interest rates were high. It was and in some cases still is, a way to help you finance the purchase of a home with low interest rates. It is an ideal choice for those who expect their income to rise or plan to move in a couple of years. An ARM also increases your risk for higher payments. Fortunately, lenders also offer safeguards to limit some of your risk to excessively high interest rates.

ARM Features

An ARM starts with a low interest rate, up to 3% lower than a fixed rate mortgage. With lower rates, you usually qualify to borrow more than with a fixed rate home loan.

ARMs usually start with a fixed rate period and end with fluctuating yearly interest rates, increasing or decreasing your monthly payment. So a 3/1 ARM means 3 years of fixed rates, with interest rates changing every year after that. Interest rates are based on an index, usually the rate on the T-bill or LIBOR, and the margin the lender adds to the index.

ARM Safeguards

In order to protect borrowers from sky-rocketing monthly payments, mortgage lenders put in place safeguards. For example, a point cap limits how much interest rates can rise monthly and over the life of the loan. There are also floor limits on how low rates can go, protecting the lender.

Many lenders also allow you to convert your ARM to a fixed rate mortgage after a predetermined period.

ARM Considerations

While an ARM has many benefits, there are other considerations to look at. For example, interest rates can rise 5% or more over the course of your home loan. If you plan to stay in your home for several years, a fixed rate may offer lower interest costs in the long term. ARMs are also unpredictable, which makes planning long term financing goals difficult.

Before you apply for an ARM, make sure you are comfortable with the level of risk involved. However, if you expect your income to rise in the future or to move in the next few years, then you may be saving yourself a lot of money in interest payments with an ARM.
