Adjustable Rate Mortgage (ARM): Meaning, Types & Advantages

An Adjustable-Rate Mortgage (ARM) is a type of home loan where the interest rate can fluctuate over time. With an ARM, the starting interest rate is fixed for a certain length of time. Following that, the interest rate applied to the outstanding debt is reset regularly, such as once a year or even monthly. ARMs are alternatively referred to as variable-rate mortgages or floating mortgages. The interest rate for ARMs is adjusted using a benchmark or index plus an extra spread known as an ARM margin. The London Interbank Offered Rate (LIBOR) was the standard index for ARMs until October 2020, when it was replaced by the Secured Overnight Financing Rate (SOFR) to boost long-term liquidity.

Geeky Takeaways:

• An adjustable-rate mortgage is a type of house loan in which the interest rate fluctuates regularly based on the performance of a certain benchmark.
• ARMs are sometimes known as variable-rate or floating mortgages.
• ARMs typically feature limitations that limit how much the interest rate and/or payments may climb each year or during the loan’s term.
• An ARM might be a wise financial decision for purchasers who want to maintain the loan for a short amount of time and can afford any possible interest rate hikes.

ARMs are typically classified into following three types:

1. Hybrid ARM: Hybrid ARMs provide a combination of fixed and adjustable rate periods. The interest rate on this form of loan will be fixed at the outset and then begin to fluctuate at a set time. This information is often given as two integers. In most circumstances, the first number denotes the amount of time that the fixed rate is placed on the loan, while the second relates to the duration or adjustment frequency of the variable rate.

2. Payment Option ARM: A payment option ARM, as the name suggests is an ARM with many payment alternatives. These alternatives often include paying both principle and interest, paying only the interest, or paying a minimal sum that does not even cover the interest. Choosing to pay the minimum amount or simply the interest may sound enticing. However, keep in mind that you must repay the lender in full by the contract’s due date and that interest costs increase when the principle is not paid promptly. If you keep paying off little amounts, your debt will continue to climb, maybe to untenable proportions.

3. Interest-only (I-O) ARM: It is also possible to obtain an interest-only (I-O) ARM, which effectively means that you will only pay interest on the mortgage for a set period of time, usually three to ten years. When this term expires, you must pay both the interest and principal on the loan. These programs appeal to consumers who want to pay less on their mortgage in the first few years so that they may save money for other things, such as buying furnishings for their new house. Of course, this benefit has a cost: the longer the I-O period, the greater your payments will be when it expires.

1. Low Rate: The most obvious benefit is that a low rate, particularly an introductory or teaser rate, will save you money. Not only will your monthly payment be cheaper than most standard fixed-rate mortgages, but you may also be able to put more money down on your principle balance.

2. Ideal For Short-Term Purchases: ARMs are ideal for consumers looking to finance a short-term purchase, such as a starter house. Alternatively, you may choose to use an ARM to finance the purchase of a house that you plan to flip.

3. Saved Expense: With an ARM, you will have more money in your pocket to spend towards savings or other goals, like a trip or a new automobile.

4. Adjusted Rate: Unlike fixed-rate customers, you will not need to go to the bank or lender to refinance when interest rates fall. That’s because you’re probably already receiving the greatest bargain around.

1. Payments May Increase Due to Rate Hikes. One of the biggest disadvantages of ARMs is that interest rates will fluctuate. This implies that if market conditions cause interest rates to rise, you’ll have to pay more for your mortgage each month. That might put a strain on your monthly budget.

2. Not as Predictable as Fixed-Rate Mortgages: ARMs may be flexible, but they do not give the certainty that fixed-rate loans do. Borrowers with fixed-rate loans know what their payments will be throughout the duration of the loan because the interest rate does not vary. However, because ARMs have variable interest rates, you will have to juggle your budget with each rate adjustment.

3. Complicated: Even the most experienced borrower may struggle to grasp these mortgages. There are several elements associated with these loans that you should be aware of before signing your mortgage agreement, including limitations, indices, and margins.

4. Risk of Negative Amortization: Some ARMs come with the possibility of negative amortization, where the monthly payment may not cover the full amount of interest owed. In such cases, the unpaid interest is added to the loan balance leading to higher overall borrowing costs and potential challenges in building equity in the home.

You may want an ARM in the following cases:

• Not Long-Term: If you don’t intend to stay in your property for long term, you may take advantage of the low initial interest rate and sell before the rate rises to a possibly higher level.
• Expect to Earn More: A changing interest rate is excellent for borrowers who are financially prepared to absorb the increase in expenditures. If you believe your salary will increase over the following few years, your bank account may be able to afford an ARM.

You may prefer a fixed-rate mortgage in the following cases:

• You’re Purchasing Your Lifelong Home: For borrowers considering a long-term home purchase, changing interest rates may not be the best option. If you want to live in your home for many years, a fixed-rate mortgage may be a preferable option since it is stable and constant.
• You Follow a Rigid Budget: Fixed-rate loans require you to pay the same amount every month, so you understand exactly what you’re accountable for. If your budget is limited, ARMs may be too expensive, even if the transition is only a few years away.

What is an ARM, and how does it work?

An Adjustable-Rate Mortgage (ARM) is a type of home loan where the interest rate can fluctuate over time. Initially, there’s a fixed period with a lower interest rate. After that, the rate can go up or down depending on market conditions, which affects your monthly payments.

Are there limits on how much my payments can increase?

Yes, US laws often require ARMs to have limits or “caps” on how much your interest rate and monthly payments can increase. These caps provide some protection for borrowers against sudden and significant payment hikes.

Can I switch from an ARM to a fixed-rate mortgage later on?

Yes, you may have the option to refinance your ARM into a fixed-rate mortgage if you prefer more stability in your payments. However, this process may involve fees and qualification requirements, so it’s essential to consider the costs and benefits carefully.

What happens if I can’t afford my payments when the interest rate adjusts?

If you’re having difficulty making payments after the interest rate adjustment, you may be eligible for assistance programs or loan modifications. It’s crucial to contact your lender as soon as possible to discuss your options and avoid defaulting on your loan.

Are there any risks I should be aware of with ARMs?

Yes, while ARMs can offer lower initial payments, they also come with the risk of higher payments if interest rates rise. Additionally, some ARMs may have features like negative amortization, where your loan balance can increase over time if your payments don’t cover the full interest amount.
