COAST CENTRAL CREDIT UNION

As of July 18, 2026, the Adjustable-Rate Mortgage (ARM) for Purchase remains steady at 3.858%, unchanged from one week ago. Compared to 30 days prior, this rate has increased by 10.8 basis points, reflecting a modest rise in borrowing costs over the past month. This upward movement may influence buyers who prefer adjustable rates, potentially increasing monthly payments after initial fixed periods.
For members considering purchase loans with adjustable terms, maintaining awareness of yield spreads is crucial; even small rate upticks can affect long-term affordability. First-time homebuyers should evaluate how these fluctuations impact their payment flexibility, while seasoned buyers might weigh the benefits of locking in a fixed rate if they prioritize payment stability.
Given the current trend, members are advised to carefully assess their mortgage strategy and consider refinancing options if projected savings outweigh associated costs. For details, visit https://www.coastccu.org/personal/mortgage-loans/.

HAWAII STATE FEDERAL CREDIT UNION

As of July 18, 2026, 30-Year Adjustable Rate Mortgages (ARMs) for purchase show a yield increase to 5.625%, rising by 12.5 basis points over the past week and 25 basis points in the last 30 days. This upward shift reflects a higher cost of borrowing for buyers opting for this adjustable product. Meanwhile, the 40-Year ARMs remain steady at 5.875%, unchanged from last week but up by 12.5 basis points compared to 30 days ago.
For first-time buyers and those managing long-term affordability, the recent rise in ARM rates suggests evaluating fixed-rate options if rate stability is a priority. Members considering adjustable terms should monitor these trends closely, as incremental increases affect future payment adjustments. Veterans and refinancing applicants should note these movements when assessing loan suitability.
Given current market dynamics, members are advised to consider refinancing only if projected savings outweigh associated costs and to reassess mortgage strategies regularly based on updated rate data.

LIGHTHOUSE FEDERAL CREDIT UNION

On July 18, 2026, adjustable-rate mortgage products for home purchase held steady, with no change in yields over the past week or month. The 3/1 ARM (Conforming) and Home 97 5/1 ARM remain at a competitive 5.50%, representing the lowest rates available today among adjustable options. The Home 100 7/1 ARM and 40-Year 7/1 ARM are priced at 5.625%, while the longer-term Home 100 10/1 ARM stands at 6.00%. Stability in these yields suggests limited movement in borrowing costs, benefiting buyers who prefer adjustable terms with initial lower rates than fixed alternatives.
Members considering purchase loans should evaluate their risk tolerance for rate adjustments after initial fixed periods. Veterans and first-time buyers might find value in shorter ARMs with lower starting points, while those seeking longer adjustment intervals may weigh the cost implications of the 10/1 ARM despite its higher rate. Given unchanged spreads, it is prudent to assess your mortgage strategy carefully; consider fixed-rate options if you prioritize payment stability or explore refinancing if market conditions shift meaningfully.
