AFFINITY PLUS FEDERAL CREDIT UNION
On May 15, 2026, Conventional Refinance rates remain steady with the 15-Year Fixed-Rate at 5.75% and the 30-Year Fixed-Rate at 6.25%; both unchanged from last week but up by 12.5 basis points over the past 30 days. This modest increase in yield spreads raises the cost of borrowing for homeowners considering refinancing. Borrowers prioritizing shorter-term payoff may find the 15-year fixed option, currently the lowest rate available, beneficial for reducing interest expenses despite slightly higher monthly payments. Conversely, those seeking longer-term stability face a similar rate trend with the 30-year fixed product. Members should evaluate if their refinancing savings exceed associated costs given these rate movements and consider locking in fixed rates to mitigate future market volatility.
