A mortgage interest rate lock is something worth considering this September, especially before potential rate increases. Although 2026 began with optimism about cooling rates and affordable homebuying, the reality presents a different scenario. The Federal Reserve’s actions last year, reducing interest rates three times in the last quarter of 2025, hinted at a more promising future. However, as of September 1, the average mortgage interest rate stands at 6.87% for a 30-year mortgage, as reported by Zillow. This rate is over a full percentage point higher than six months prior.

Despite today’s high rates, securing a mortgage rate can still be beneficial. Understanding the reasons behind this idea is crucial.

Why Locking a Mortgage Rate Makes Sense This September

Protecting your mortgage interest rate in September is wise, given the circumstances. Here’s why:

The Federal Reserve Could Elevate Rates

The Federal Reserve might raise interest rates in its upcoming meeting. Based on predictions by the CME Group’s FedWatch tool, there’s a solid 66% chance of a rate hike on September 16. What currently is a “high” rate might soon seem “low.” By locking in now, you shield yourself from a possible increase later. If rates drop before closing, consider unlocking your rate or planning to refinance in the future. Missing this chance could be costly, potentially delaying your home purchase indefinitely.

Rate Changes May Happen Ahead of Fed’s Decision

Lenders often adjust their rates earlier than official increases from the Fed. They watch closely economic indicators like inflation or unemployment, which might justify higher rates even before a Fed announcement. Getting a good rate lock now avoids facing these sudden changes and the financial impacts that follow.

This May Signal More Upcoming Rate Hikes

Should rates rise in September, it might be the start of frequent rate hikes, not a one-time case. With meetings scheduled for October and December, it’s wise to lock rates early and avoid future increases. Confirming your rate now helps plan for home purchases, ensuring you know your budget and buying power.

The Takeaway

Securing a mortgage rate close to 7% might not appear cost-effective. Nevertheless, with a potential September rate hike and lenders possibly increasing offers beforehand, quick action might prevent future financial strain. Also, consider understanding mortgage rate float down options as they vary between lenders, should rates unexpectedly decrease.
