AFFINITY FEDERAL CREDIT UNION

On December 13, 2025, the 7/6 ARM Adjustable Purchase mortgage remains steady at 4.75%, with no change over the past 7 or 30 days. This stable yield spread indicates a consistent cost of borrowing for members seeking adjustable-rate purchase loans. For first-time buyers, this rate stability provides predictable initial payments before potential adjustments after seven years. Veterans and those considering refinancing should note that while this product offers short-term rate advantages, evaluating fixed-rate options might better suit long-term budgeting needs.

Consider refinancing only if projected savings exceed transaction costs. For details, visit https://www.affinityfcu.com/about-us/rates#:~:text=Mortgages,-Loan%20Type.

COAST CENTRAL CREDIT UNION

As of December 13, 2025, the 30-year Adjustable-Rate Mortgage (ARM) for Purchase remains steady at 4.25%, unchanged from one week ago but down by 11.3 basis points compared to 30 days prior. This subtle yield spread reduction slightly lowers the cost of borrowing for prospective homebuyers opting for adjustable rates, potentially enhancing affordability in a fluctuating rate environment. For members considering adjustable terms, this stability suggests limited short-term volatility; however, evaluating fixed-rate alternatives may be prudent for those prioritizing payment predictability. First-time buyers can benefit from locking in current ARM rates while monitoring market shifts, whereas veterans and refinancing applicants should weigh these dynamics against long-term financial goals. Given these trends, members should assess their mortgage strategy carefully and consider refinancing if potential savings exceed associated costs.

COMMUNITY 1ST CREDIT UNION

As of December 13, 2025, the 10/1 ARM Adjustable Purchase mortgage remains at a rate of 6.0%, unchanged from one week ago but down 25 basis points compared to 30 days prior. This yield spread reduction signals a moderate easing in borrowing costs for members opting for adjustable-rate financing. For first-time homebuyers or those planning shorter-term ownership, this stability in the 10/1 ARM offers predictable initial payments with potential savings versus fixed alternatives. However, borrowers should evaluate interest rate trends carefully given the inherent variability after the initial fixed period. Members considering refinancing should analyze their long-term cost implications relative to current adjustable rates and may find value in locking rates if seeking payment certainty. Consider your mortgage strategy in light of these movements to optimize financial outcomes.

This upward movement reflects a modest widening in yield spreads and increases the cost of borrowing for prospective buyers opting for this variable-rate product. Members considering this option should evaluate how these rate fluctuations impact monthly payments over time, especially given the adjustable nature after the initial fixed period. For those prioritizing payment stability, assessing fixed-rate alternatives may be prudent. First-time buyers and investors should monitor these changes closely to balance initial affordability against potential future rate adjustments.
