AFFINITY PLUS FEDERAL CREDIT UNION
As of March 27, 2026, conventional refinance mortgage rates have risen notably. The 15-Year Fixed-Rate Conventional loan now stands at 5.875%, up by 12.5 basis points compared to last week and 50 basis points higher than 30 days ago. Meanwhile, the 30-Year Fixed-Rate Conventional refinance rate increased more sharply to 6.5%, reflecting a 37.5 basis points rise over the past week and a 62.5 basis points increase since one month ago.

Borrowers with shorter loan horizons may find the 15-year fixed option comparatively less expensive but should weigh accelerated amortization against current rates.
Members are advised to carefully evaluate their refinancing strategies; consider locking in fixed-rate loans if prioritizing payment predictability or delaying refinancing if market conditions improve. Cost-benefit analysis of interest savings versus closing costs remains essential.

Conclusion
Even small shifts in mortgage rates can affect your monthly payments and total interest over time. With several credit unions raising their 30-year fixed rates by up to 50 basis points recently, it’s wise to weigh whether now is the moment to refinance or buy. For homeowners with shorter-term goals or who want quicker payoff, the 15-year fixed at 5.125% from Navy Federal Credit Union remains an attractive option. Keep an eye on inflation trends as they often signal future rate changes; lower inflation expectations could ease borrowing costs down the line. Ultimately, take a close look at your financial goals and loan terms, sometimes a slightly higher rate with fewer points means less cash upfront and more flexibility. Staying informed lets you choose confidently and avoid surprises when closing day arrives.
