COAST CENTRAL CREDIT UNION
As of December 27, 2025, the 30-year Adjustable-Rate Mortgage (ARM) for Purchase remains steady at 4.25%, unchanged from one week ago but down 11 basis points compared to 30 days prior. This stability in yield spreads suggests a modest reduction in the cost of borrowing over the last month, which may benefit buyers seeking initial lower rates with potential future adjustments. First-time homebuyers and those planning purchases can leverage this rate environment while monitoring market shifts. Given the absence of movement in the past week, members should evaluate whether an adjustable rate aligns with their risk tolerance or consider fixed-rate options for long-term predictability. For members weighing refinancing decisions, assessing current ARM terms against fixed alternatives is advisable to optimize financial outcomes.

ST. MARY'S BANK CREDIT UNION
On December 27, 2025, the 15- to 30-year Adjustable Rate Mortgage (5/6 ARM) for Purchase stands at 5.875%, marking a notable decline of 25 basis points compared to one week ago and a moderate decrease of 12.5 basis points relative to 30 days prior. This reduction in yield spreads lowers the immediate cost of borrowing for buyers opting for this adjustable product. Members considering an adjustable purchase loan can benefit from this dip, especially those expecting stable or declining interest rates over the medium term. However, with rates still above 5.8%, borrowers valuing payment predictability should assess if fixed-rate options might better suit their financial strategy. Given these trends, members are advised to evaluate their mortgage choices carefully and consider refinancing if projected savings exceed associated costs.

STATE DEPARTMENT FEDERAL CREDIT UNION
As of December 27, 2025, Conforming Adjustable-Rate Mortgages (ARMs) for purchase show relatively stable yields. The lowest rate remains the 5/5 ARM at 5.125% with 0.625 points, unchanged over the past week and month, indicating steady borrowing costs for short-term adjustable products. The 7/6 ARM decreased by 12.5 basis points week-over-week to 5.125%, offering a marginally improved yield spread for borrowers seeking a longer initial fixed period before adjustment. Meanwhile, the 10/6 and 15/15 ARMs hold firm at 5.375% and 5.25%, respectively, with no recent movement.
For members evaluating mortgage strategies, these trends suggest that shorter fixed periods with ARMs maintain consistent cost structures, benefiting those comfortable with periodic adjustments. Borrowers should consider their risk tolerance; if stability is preferred, fixed-rate options might be more suitable despite slightly higher initial rates elsewhere. Additionally, refinancing assessments should weigh potential savings against adjustment risks.

VANTAGE CREDIT UNION
As of December 27, 2025, adjustable-rate mortgage (ARM) products for home purchases have maintained stable pricing with no changes in yield spreads over the past week or month. The 7/1 ARM and 10/1 ARM hold steady at 6.12% and 5.875%, respectively, while the 15/15 ARM remains at 6.00%. Notably, the 10/1 ARM’s rate of 5.875% is the lowest available among adjustable options today. For members considering variable rate loans, this stability suggests predictable short-term borrowing costs without recent volatility.
First-time buyers and those prioritizing lower initial rates might evaluate these ARMs to manage monthly payments effectively. However, borrowers should weigh potential future rate adjustments beyond fixed periods against their long-term financial plans. Veterans and refinancing applicants might find limited movement in cost of borrowing; thus, assessing individual mortgage strategies aligned with interest rate projections remains essential.
Given current conditions, members should consider refinancing only if projected savings exceed associated fees or explore fixed-rate alternatives for greater payment certainty over time. For details, visit https://www.vcu.com/rates#mortgage-rates.
