In the following paragraphs, we will cover what is the difference between ARM versus fixed-rate mortgages.

What is an ARM:  Adjustable Rate Mortgages

The difference between adjustable rate mortgages and fixed-rate mortgage loans is ARMs are home loans with interest rates that can change over time. Unlike fixed-rate mortgages, where the interest rate stays the same throughout the life of the loan, the rate on an ARM will adjust after a fixed period based on the performance of a specific benchmark or index. Here’s how ARMs work:

Initial Fixed-Rate Period of an ARM

ARMs start with an introductory period when the interest rate remains fixed. This period typically lasts for 1, 3, 5, 7, or 10 years, depending on the specific terms of the mortgage.

Adjustment Periods of an ARM

The interest rate adjusts regularly after the initial fixed-rate period. The frequency of rate adjustments is part of the loan agreement and could be every year, every three years, or another interval.

Components of Adjustable-Rate Mortgages

Index: The rate adjustments are tied to a financial index, such as the London Interbank Offered Rate (LIBOR), the Cost of Funds Index (COFI), or the Secured Overnight Financing Rate (SOFR). These indexes reflect the cost of borrowing money and fluctuate based on market conditions.

Margin Component of Adjustable-Rate Mortgages

Margin: Lenders add a fixed number of percentage points, known as the “margin,” to the index value to determine the ARM’s interest rate at each adjustment. The margin remains constant over the life of the loan.

Adjustable Rate Mortgage Interest Rate Caps

ARMs typically include caps that limit how much the interest rate or the monthly payment can increase at each adjustment period and over the life of the loan. These caps provide some protection against drastic increases in payments:

  • Initial Cap: This cap limits the amount the interest rate can increase the first time it adjusts after the fixed-rate period.
  • Periodic Cap: This cap limits the interest rate increase from one adjustment period to the next.
  • Lifetime Cap: This cap limits the total increase in the interest rate over the life of the loan.

Pros and Cons of Adjustable-Rate Mortgages

Advantages: ARMs’ initial interest rates are usually lower than those of fixed-rate mortgages, which can make them more affordable in the short term. This can be particularly attractive if buyers plan to sell or refinance before the end of the initial fixed-rate period.

Disadvantages: The potential for future rate increases adds uncertainty, as monthly payments can increase significantly over time, particularly in a rising interest rate environment.

ARMs are suited for certain financial strategies and goals, particularly for those who anticipate an increase in income, plan to move or refinance before rates adjust, or expect interest rates to decline. However, borrowers should consider their ability to handle potential payment increases over time.  Click Here to touch with our experts for more information

The adjustable-rate mortgage normally quoted is the initial start rate of the lender. The initial fixed-rate period on an adjustable-rate mortgage is three, five, or seven years.
