ALABAMA CREDIT UNION
As of August 22, 2026, Alabama mortgage rates for adjustable-rate mortgages remain stable with no changes over the past week or month. The 3/1 ARM First Mortgage offers the lowest rate at 5.0% with 0 points, maintaining consistent yield spreads. Mid-term options such as the 5/5 ARM at 5.875% and the 7/1 ARM at 6.0% hold steady, reflecting no fluctuations in cost of borrowing. The longer 10/1 ARM First Mortgage is priced at 6.5% with 0.5 points, also unchanged.
For members considering purchase loans, this stability supports predictable initial payments; however, potential rate adjustments after fixed periods should be evaluated carefully. First-time buyers might find the 3/1 ARM’s lower entry rate advantageous, while those valuing payment certainty may want to assess fixed-rate alternatives elsewhere.
Given these data points, members should evaluate their mortgage strategy in light of unchanged adjustable rates and consider refinancing only if potential savings outweigh associated costs. For details, visit https://www.alabamacu.com/lending/home-loans/mortgage-rates.
COAST CENTRAL CREDIT UNION
As of August 22, 2026, the Adjustable-Rate Mortgage (ARM) for Purchase remains steady at a 3.858% interest rate with 0.0 points, unchanged over the past week and month. This stability in yield spreads means the cost of borrowing through adjustable-rate purchase loans has not fluctuated, providing predictability for members considering this product. For first-time buyers or those seeking lower initial rates with potential future adjustments, this consistent ARM rate supports informed mortgage planning without immediate rate pressure.
Members should evaluate their mortgage strategy carefully; if long-term payment certainty is a priority, exploring fixed-rate alternatives may be prudent. Conversely, those comfortable with potential rate variability might find the current ARM rate advantageous for initial affordability.

LIGHTHOUSE FEDERAL CREDIT UNION
As of August 22, 2026, adjustable-rate mortgage (ARM) products for home purchases show a modest decline in borrowing costs. The 3/1 ARM (Conforming) and Home 97 5/1 ARM both decreased by 12.5 basis points, now at 5.625%, representing the lowest rates available today. Similarly, the Home 100 7/1 ARM and the extended-term 40-Year 7/1 ARM each fell by 12.5 basis points to 5.75%, offering longer adjustment periods with slightly higher yields. The 10/1 ARM also dropped by 12.5 basis points to 6.125%, reflecting wider yield spreads for longer fixed terms.
For members planning new purchases, lower initial rates on shorter ARMs may reduce upfront costs but entail rate adjustments after the fixed period. Veterans and long-term buyers might weigh the stability of longer ARMs despite their higher starting rates. Consider your refinancing strategy carefully; if current savings exceed closing costs, an ARM could optimize cash flow while fixed-rate alternatives may suit those valuing payment predictability.

SIERRA CENTRAL CREDIT UNION
As of August 22, 2026, the 5/1 Adjustable Rate Mortgage (ARM) for purchase loans is priced at 5.875% with 1.0 point, reflecting a decline of 12.5 basis points compared to last week’s rate of 6.0%. This reduction in yield spread decreases the cost of borrowing for members opting for adjustable-rate products. While this adjustment benefits buyers seeking initial lower rates with future variability, it is essential to consider potential rate increases after the initial fixed period. Members prioritizing payment stability should assess whether an ARM aligns with their long-term financial strategy. Given current market movement, evaluate if refinancing or purchasing with an ARM offers cost advantages relative to fixed-rate options.
