FHA Adjustable Rate Mortgages in 2021
February 21, 2021
The Index Changes
Lenders use a specific market index off of which an ARM’s interest rates are based. Until recently, most financial institutions, including the FHA, were using the London Inter-bank Offered Rate (LIBOR), but it was decided that effective January 3, 2022, the mortgage industry will put aside LIBOR and adopt the Secured Overnight Funding Rate (SOFR). The U.S. Federal Reserve Board and New York Federal Reserve are set to oversee the transition from LIBOR to SOFR, and have recommended that most new ARMs use SOFR instead of LIBOR beginning in September, 2020.
Why Does This Matter?
To understand why this change matters, you must know how an ARM works. The interest rate you get with an ARM is based on an index and a margin (which is disclosed when you apply for the loan). Your adjustable rate is calculated by adding the loan margin to the index, so as the index figure changes, so will your interest rate.
With the implementation of a new index, the changing rates of ARMs may start to look different. While both LIBOR and SOFR are used to measure the cost of short-term borrowing, the indexes measure that cost differently. Greg McBride, chief financial analyst at Bankrate states that, “SOFR is based on actual market transactions whereas LIBOR was determined by what various banks would charge each other to borrow on an overnight basis.” When it became clear that certain banks were able to manipulate the LIBOR rate, SOFR was created to be a more accurate and reliable index that is less susceptible to such manipulation.
While the majority of borrowers and loan applicants will not be affected by the new mandate, those with adjustable- rate mortgages, a home equity loan, or a reverse mortgage might see changes to their loan depending on how it is indexed.
McBride states that ARMS based on LIBOR will no longer be purchased by Fannie Mae and Freddie Mac. "SOFR is rapidly replacing it. Treasury-indexed ARMs are unaffected.”
Next Steps
It is important for borrowers to be in the know, and stay on top changes in their interest rate. While it is expected that the changes will relatively minor, mortgage holders with an ARM should contact their loan servicers to see which index their mortgage is based on, to avoid being caught off guard with the next adjustment. If the loan is tied to LIBOR, lenders can help identify when it will switch to SOFR and what that change could mean for the particular ARM.

August 19, 2026Homebuyers who have enough cash for a down payment still need to consider their full financial picture before choosing between a conventional mortgage and an FHA loan. Having cash on hand changes the math for both options, but savings alone won't make a conventional loan the automatic winner. Credit scores, current debt, and the type of property you want to buy all determine which loan will cost less over time.
August 11, 2026Homeowners with FHA adjustable-rate loans need to track their loans more closely. That is because FHA ARM loans start with introductory interest rates that eventually expire and are subject to change afterwards based on market rates. When interest rates rise, monthly housing payments climb on ARM loans, pushing many homeowners to consider refinancing into a fixed-rate mortgage.
August 10, 2026If you want to buy a home with an FHA mortgage, you must set up an escrow account to cover property taxes, homeowner insurance, and upfront closing expenses. While the FHA loan program has rules for funding these accounts, buyers often do not realize those rules can include approved and unallowed sources for escrow funds. What do you need to know before you set up and fund your escrow account for an FHA mortgage?
August 3, 2026Buying a home in a high-cost area requires understanding how FHA loan limits shape your financing options. Does the house for sale have a price above the local FHA loan limit? You may need to explore your jumbo loan options. There are conventional jumbo loans and FHA versions. Which is right for you? Much depends on your financial needs, plans, and goals for the loan.
July 30, 2026There is a common misconception about FHA loans that only a first-time home buyer can use the program. This is not true; repeat buyers can qualify for an FHA loan, but why does this misconception exist? Partially because state and local programs have first-time buyer requirements for down payment and/or closing cost assistance programs. So while you do not need to be a first-time buyer to get an FHA loan, you may need to meet that definition to qualify for down payment help.
