Conclusion
Looking ahead, even small shifts in mortgage rates matter more than they might seem at first glance. A quarter-point change on a jumbo 30-year loan can add hundreds to your monthly payment and thousands over the life of the loan. With some Credit Unions lowering their 30-year jumbo fixed rates by up to 25 basis points, it’s worth shopping around carefully and timing your lock wisely. Keep an eye on inflation trends reported by FRED, as they often signal future rate moves. If you’re planning a refinance or purchase, consider shorter terms like the 15-year fixed at Hudson Valley’s 4.5%, which can save interest and help build equity faster. Staying informed and proactive will help you make decisions that fit your financial goals with confidence.
