How to get the best ARM rate

• Step 1: Strengthen your finances - Before applying for an ARM, give your finances a checkup. See if you can improve your credit score, ideally to be “very good” at least. A better credit score, lower debt-to-income (DTI) ratio and higher down payment will result in a more favorable interest rate.
• Step 2: Determine your budget - You’ll need a good handle on how much house you can afford before shopping for an ARM. Using an adjustable-rate calculator can help you estimate how your mortgage payment could swing once the rate adjusts.
• Step 3: Compare ARMs: Compare a variety of ARMs — like 5/1 or 5/6 ARMs, 7/1 ARMs and 10/1 ARMs — to determine which fits you best. The introductory rates are higher on longer-term ARMs, but the tradeoff is that the fixed-rate period lasts longer.
• Step 4: Compare rates and terms from several lenders - Rate-shop with at least three different banks or mortgage companies to find the best ARM offer. Keep an eye on the fine print, understanding the interest rate, fees and rate cap structure for the ARM.

ARM loan requirements

When compared to other types of mortgages, ARMs typically have stricter requirements. That’s because lenders need to consider your ability to repay the loan if your rate moves higher.

• Loan amount: In 2024, homebuyers can borrow up to $766,550 for a conforming ARM (limits are higher in areas with higher home prices). You can take on a jumbo ARM which exceeds the conforming loan limit, though both these types of loans might be harder to secure.
• Credit and income: With a higher credit score, you’re more likely to get a competitive interest rate. Lenders will also look at other factors such as other debt and income.
• Down payment: Most conventional ARM loans require as little as 5 percent down.

When is it a good idea to get an adjustable-rate mortgage?

Consider your current financial situation and goals. Here are some scenarios where an ARM might be a good idea:

• You can get a significantly lower APR on the ARM than with a fixed-rate mortgage
• You plan to move or refinance before the initial rate period ends

There are positives and negatives when it comes to ARMs, however. Let’s break down the pros and cons further:

What is an adjustable-rate mortgage and how does it work?

The most common types of ARMs are known as hybrid ARMs, which have an initial fixed-rate period followed by a floating rate for the remainder of the loan. You may see these listed as 5/6 ARM or a 7/1 ARM, where the first number indicates how long the fixed rate lasts and second number indicates how often the rate adjusts (“6” for every six months, “1” for annually). Here’s a rundown of the most popular types:

• 3/1 ARM or 3/6 ARM: The first three years have a fixed rate followed by a floating rate for the remainder of the loan.
• 5/1 ARM or 5/6 ARM: The first five years have a fixed rate followed by a floating rate for the remainder of the loan.
• 7/1 ARM or 7/6 ARM: The first seven years have a fixed rate followed by a floating rate for the remainder of the loan.
• 10/1 ARM or 10/6 ARM: The first 10 years have a fixed rate followed by a floating rate for the remainder of the loan.

Usually, 5/1 ARMs have the lowest interest rate of the bunch. 

Further variations include FHA ARMs and VA ARMs, which are basically the government-backed versions of a conventional ARM, with their own set of qualifications. Convertible ARMs are another option, albeit less common. These are ARMs that allow you to convert your balance to a fixed rate, usually for a fee.
