Adjustable-Rate Mortgage (ARM) – Requirements And Loan Limits For 2021

Get a more affordable interest rate and lower monthly payments at the start of your mortgage.

What’s An Adjustable-Rate Mortgage (ARM)?

With our adjustable-rate mortgages, your interest rate is fixed for a specific time period – usually five, seven or 10 years. After that, your interest rate may change every six months, depending on the market. That means your monthly mortgage payment could go up or down twice a year. Your rate won’t increase more than 5% of the original rate throughout the life of the loan, though.

Our adjustable-rate mortgages are shown as two numbers with a slash in between. The first number shows how many years the interest rate is fixed. The number after the slash shows how many months the adjustment period is. For example, our 5/6 ARM offers a fixed rate for five years, then the rate adjusts every six months.

What’s The Difference Between ARMs And Conventional Mortgages?

Conventional mortgages, or fixed-rate mortgages, keep the same interest rate over the life of the loan.

Adjustable-rate mortgages, on the other hand, start with a low fixed interest rate for five, seven or 10 years, and then adjust the rate periodically after that. The initial fixed interest rate on our ARMs is usually lower than the corresponding 30-year fixed interest rate.

ARM Mortgage Rates

Our ARM interest rates are based on a combination of factors, including today’s mortgage rates, the Secured Overnight Financing Rate (SOFR) index and caps.

SOFR Index

The Secured Overnight Financing Rate (SOFR) measures the cost of borrowing cash overnight and is calculated by the New York Federal Reserve. We use the SOFR index’s 30-day average to help determine interest rates for our adjustable-rate mortgages.  


Each adjustable-rate mortgage has a cap that limits how much the interest rate can change up or down at each adjustment date and over the life of the loan.

There are three caps:

  • Initial cap sets the ceiling and the floor for the rate of the first adjustment.
  • Periodic cap sets the ceiling and the floor for the rate at each subsequent adjustment.
  • Lifetime cap sets the ceiling and the floor for the rate over the life of the loan.

These caps are shown as a series of three numbers with slashes in between. For example, our 5/6 ARM caps are 2/1/5. The first number means that after five years of fixed-rate interest, the first adjustment is capped at 2%. Every adjustment after the initial cap can only go up or down 1%. The final number means the total interest over the life of the loan cannot go up or down more than 5%.

Our Adjustable-Rate Mortgage Caps

  • 5/6 ARM caps are 2/1/5
  • 7/6 ARM caps are 5/1/5
  • 10/6 ARM caps are 5/1/5

Calculating The New Payment

When a rate adjusts, here’s what we use to calculate the new payment:  

  • The current unpaid principal balance of the loan 
  • The new interest rate 
  • The remaining term of the loan 

Since each re-calculation uses the remaining term of the original 30-year loan, you’ll always remain on track to pay off your loan 30 years after the date you close, as long as you stay current with your payments.  

What You’ll Need To Qualify For An ARM

  • A minimum 5% down payment
  • A minimum FICO® Score of 620
  • debt-to-income ratio (DTI) of no more than 50%. Estimate your DTI by adding your monthly debt payments (such as credit card and car payments) and dividing the total by your monthly income before taxes.
  • maximum loan-to-value ratio (LTV) of 95% 

Can You Refinance An Adjustable-Rate Mortgage?

Yes, you can refinance an adjustable-rate mortgage. With today’s low interest rates, refinancing an ARM can give you the stability of the same monthly payment for years to come. Refinancing could also help you consolidate debt or pay off your mortgage faster. Apply online or contact our experts at (800) 251-9080 to get started.

Adjustable-Rate Mortgage Benefits

  • A key benefit of an ARM is that the initial rate is typically lower than a fixed-rate mortgage, which makes monthly payments more affordable.
  • Caps limit how much interest rates, and your payment, can rise over the life of the ARM loan.
  • An ARM can be a wise choice if you’re planning to pay off the loan in full, or sell your home, before the adjustment period kicks in.
  • For many people, the initial fixed-rate period matches how long they’ll be in their home before they move or refinance.
  • There’s a possibility your payment could go down if interest rates fall.
