Mortgage rates are the highest they've been in almost three years. For buyers on the Connecticut Shoreline and in Central CT, that means a bigger monthly payment on homes that already cost more than they did a year ago. More buyers are now asking lenders about an adjustable-rate mortgage (ARM) to bring that payment down.
What the numbers show
The average 30-year fixed rate hit 7.5% for the week ending October 9, according to the Mortgage Bankers Association (MBA). The average 5/1 ARM rate that week was 6.54%. That gap is close to a full percentage point.
Buyers are responding. ARMs made up 10.5% of all mortgage applications that week, the highest share since October 2025 (MBA). That's roughly 1 in 10 buyers.
What that gap means for a Connecticut buyer
Home prices in Connecticut are up about 6% over last year, and the statewide single-family median is now around $500,000 (SmartMLS, Realtor.com).
Say you buy a $500,000 home in Wallingford or Middletown and put 20% down. Your loan is $400,000. Principal and interest would be about:
30-year fixed at 7.5%: $2,797 a month
5/1 ARM at 6.54%: $2,539 a month
That's about $258 a month, or roughly $15,500 over the first five years. Taxes and insurance are extra, and your actual rate depends on your credit, down payment, and lender.
How a 5/1 ARM works
A 5/1 ARM has a fixed rate for the first five years. After that, the rate can change once a year based on the market. Caps limit how much it can rise at the first adjustment, at each adjustment after that, and over the life of the loan. Your lender has to show you those caps before you sign.
Who an ARM can make sense for
An ARM fits some buyers well:
Starter-home and condo buyers who plan to move up within five to seven years.
Buyers relocating for work who expect to move again.
Buyers who plan to refinance if rates come down.
Buyers who need a lower payment now to qualify for the home they want in a competitive town like Guilford or Madison.
If you plan to stay in your home for 15 years or more, a fixed rate usually gives you more peace of mind. If you're using a CHFA loan or down payment assistance, ask your lender which loan types the program allows.
The risk to plan for
Rates could be higher when the fixed period ends. Ask your lender to show you the payment at the first cap and at the lifetime cap. Make sure you could afford the highest number.
Your options when the rate resets
When the fixed period ends, you can:
Keep the loan and pay the new rate.
Refinance into a fixed-rate loan.
Refinance into a new ARM.
Sell the home. Many Shoreline owners have built strong equity over the past five years.
Today's ARMs come with stronger protections
ARMs got a bad reputation during the 2008 housing crash. The rules have changed a lot since then. Under the federal Ability-to-Repay rule, lenders must check that you can afford the loan, including what the payment could become after it adjusts.
Talk it through before you shop
An ARM is one tool. It can help you buy sooner, or buy in the town you want. Talk to a local lender about your numbers, then let's talk about where you want to live.
