As of Thursday, August 27, 2026, mortgage rates are exhibiting a mixed trend. While some loan rates have increased, others have decreased. Notably, the 5/1 adjustable-rate mortgage (ARM) has seen a significant drop in cost compared to the previous day, making it a more attractive option for borrowers.
This creates a key choice for homebuyers: Should you take the lower 6.35% ARM rate or pay more for the stability of a 6.57% fixed mortgage? A 5/1 ARM starts with a fixed interest rate for the first five years. A 30-year fixed mortgage works differently. The 6.57% fixed rate is higher than today’s 6.35% ARM rate, but the extra cost comes with more certainty.
Because of these caps, but a significant increase can still put pressure on a household budget, mortgage broker Travis Erickson of Bonelli Financial Group said ARM loans have a maximum rate.
Erickson said a fixed mortgage can make sense for someone buying a “forever home” who wants the payment to remain predictable over the long term. The answer mainly depends on how long you expect to stay in the home and how comfortable you are with future rate changes. After that period, the rate can change at set intervals based on the terms of the loan. ARM rates are generally linked to a benchmark or index. For example, a lender may use the Secured Overnight Financing Rate (SOFR) and add a fixed percentage called the margin to determine the new rate. If the underlying index rises, the ARM’s interest rate can rise too. If the index falls, the rate can also fall, although the exact changes depend on the loan agreement. Rate caps provide some protection for ARM borrowers. The interest rate stays locked for the entire loan term, which gives borrowers more predictable principal and interest payments. A borrower does not have to worry about the mortgage interest rate suddenly increasing after five years. A fixed-rate mortgage can be a better choice for buyers who plan to stay in their home for many years. Mortgage payment risk
Your monthly principal and interest payment can rise or fall when the ARM rate changes, according to USA Today. These caps limit how much the interest rate can increase at each adjustment and how much it can rise over the life of the loan, according to USA Today. It may also suit people who do not want to take the risk of higher payments in the future, according to USA Today.
Comparing Adjustable and Fixed-Rate Mortgages
Borrowers considering a 6.35% adjustable-rate mortgage (ARM) should be aware of the potential for increased payments in the future. While the initial rate is lower, it does not guarantee sustained lower costs over the life of the loan. In contrast, the 6.57% fixed-rate mortgage offers stability, with payments remaining unchanged regardless of market fluctuations.
The 6.35% ARM may be appealing for buyers who plan to sell or refinance before the five-year fixed period concludes and are prepared for possible rate hikes later. Conversely, the 6.57% fixed mortgage is likely the better option for those intending to remain in their homes long-term or for buyers seeking predictable monthly payments. The slightly higher starting rate associated with the fixed mortgage reflects the cost of long-term payment certainty.
