ARM or 30-Year Fixed at 7%? What Austin Buyers Should Know

Should Austin buyers take an adjustable-rate mortgage with fixed rates above 7%?

An adjustable-rate mortgage can make sense for Austin buyers who expect to sell or refinance within about five to seven years, because the starting rate is lower. In early November 2026 the average 5/1 ARM was about 6.28% versus about 7.21% for a 30-year fixed (MBA). On a $378,900 loan, that start rate is roughly $209 a month less than a fixed loan at Freddie Mac's 7.11% average. The trade-off is that the rate can rise after the fixed period, so it fits best when you have a clear plan and room in your budget if it does.

With 30-year fixed rates sitting above 7%, more of my buyers are asking about adjustable-rate mortgages. They've heard the word "ARM" and they're not sure if it's a smart move or a 2008 mistake waiting to happen.

The truth is somewhere in the middle. An ARM is a tool. For some families it's a great fit, and for others it's a real risk. Here's how I'd think about it.

Where rates are right now

• 30-year fixed: 7.11% on average, Freddie Mac's November 12, 2026 survey. That was the fourth straight weekly decline and the lowest in seven weeks, but it's still about a point higher than a year ago (6.24%).
• 15-year fixed: 6.45% (same survey).
• 5/1 ARM: about 6.28%, versus 7.21% for a 30-year conforming loan, in the Mortgage Bankers Association survey for the week ending November 6. ARMs made up 10.9% of applications that week.
• The Federal Reserve held its target range at 3.75% to 4.00% on October 28, and two members voted for a hike. So nobody should be planning on rates falling quickly.

NPR's Planet Money reported this month that ARMs are only about 5% of U.S. mortgages today, compared with about a third during the run-up to the housing bubble. They're coming back, but they're still a small slice.

What the lower rate actually saves

Let's use the median home price in Austin this fall, $421,000 (Unlock MLS, September), with 10% down. That's a loan of about $378,900. Principal and interest only:

• At 7.11% fixed: about $2,549 a month
• At 6.28% for the first five years: about $2,340 a month
• Difference: about $209 a month, or roughly $12,500 over five years

That's real money. But the reason the rate is lower is that you're taking on the risk of what happens after year five.

What happens when the ARM adjusts

On a 5/1 ARM, the rate is fixed for five years and then adjusts once a year, based on an index plus a margin set in your loan. Rate caps limit how much it can move. A common setup limits the first adjustment to 2 points, each later adjustment to 2 points, and the lifetime increase to 5 points, but every loan is different, so read your own loan estimate.

Here's what the same loan could look like after five years, when the balance would be about $353,800:

• If the rate reset to 8.28%: about $2,796 a month
• If it later climbed all the way to the lifetime cap of 11.28% (with the caps above, that would take several yearly adjustments): about $3,539 a month

That worst case is about $990 a month more than the 30-year fixed payment. I'm not here to pretend that couldn't happen. It's exactly why I want every buyer to look at that number before choosing an ARM, not after.

There's a more hopeful side too. Planet Money cited a Redfin analysis going back to 1971 that found ARM borrowers had at least one chance to refinance to a lower rate about 70% of the time. That's a pattern, not a promise.

Who an ARM can make sense for

• Move-up families with a five to seven year plan. If you know this is a "for now" home, you may sell before the rate ever adjusts.
• Buyers who expect their income to grow and could handle a higher payment if it came.
• Buyers with room in their budget even at the capped payment.

Who should probably stick with a fixed rate

• Forever-home buyers who plan to stay 10 years or more.
• Buyers stretching to qualify. If the starting payment is already the most you can handle, an ARM adds risk you can't absorb.
• Anyone who would lose sleep over it. Peace of mind is worth something.

Other ways to lower your rate in Austin right now

Before you choose an ARM, compare it with the options this market gives buyers:

• Seller-paid rate buydowns. With so many Austin listings cutting their price this fall, sellers are often willing to put money toward your rate instead.
• Builder incentives on new construction, which often include a buydown.
• Assistance programs for buyers who qualify, which can lower what you need to bring to closing.

Every situation is different, and the only way to know which one fits is to run the numbers side by side with your lender.

Confirm current rates, caps, and terms with your lender.

Frequently Asked Questions

What is a 5/1 ARM?

A loan with a fixed rate for the first five years that then adjusts once a year based on an index plus a margin. Rate caps in the loan limit how much each adjustment can raise it.

Is an ARM a good idea if I plan to move in five years?

It can be. If you sell before the fixed period ends, you keep the lower payment the whole time. Make sure you could afford the adjusted payment in case your plans change.

Can I refinance out of an ARM later?

Yes, if rates drop and you qualify. Refinancing costs money, and rates may not cooperate, so don't count on it as your only plan.

Is a seller-paid buydown better than an ARM?

It depends on how long you'll keep the loan and what the seller will offer. A permanent buydown lowers your fixed rate for the life of the loan, while an ARM's savings are only guaranteed during the fixed period. Compare both with your lender.

Are ARMs as risky as they were in 2008?

Today's ARMs generally require full income documentation and have caps, and they're a much smaller share of the market. The risk that remains is a higher payment after the fixed period, which is why the capped payment matters.

The bottom line

An ARM isn't good or bad on its own. It's a trade: a lower payment now in exchange for uncertainty later. For an Austin family with a clear five to seven year plan and room in the budget, it can be a smart move. For a forever home or a tight budget, a fixed rate is usually the calmer choice.
