With potential changes to mortgage interest rates on the horizon, considering a rate lock this September could be advantageous, despite today’s rates being elevated. For homebuyers, locking in a rate can provide stability and safeguard against future hikes.
The Changing Landscape of Mortgage Interest Rates
September 2026 was anticipated to bring cooling mortgage interest rates, stemming from the Federal Reserve’s decisions in late 2025. However, the average rate as of September 1 is 6.87% for a 30-year mortgage, reflecting an upward trend compared to six months ago.
Despite this, locking a rate now could still offer a strategic advantage in today’s financial climate, regardless of whether you secure the current average or lower.
Federal Reserve Actions and Rate Locks
The likelihood of the Federal Reserve increasing rates later in September is notable, with a 66% probability according to CME Group’s FedWatch tool. Locking in a rate now could avert the impact of a prospective rate hike.
If rates drop before your loan closes, options exist to unlock or refinance, making a rate lock a protective measure.
Lender Adjustments Pre-Fed Announcements
While the Fed might raise rates on September 16, lenders often adjust their rates prior, influenced by inflation or unemployment reports. Locking in a mortgage rate before such lender adjustments can curb costs and provide protection even before the Fed’s meeting concludes.
The Potential for Additional Rate Hikes
A September rate hike might not stand alone, as meetings are still planned for October and December. A rate adjustment now could signal the onset of further hikes. Locking in protects from this possibility and aids in clarifying your home purchase budget.
Conclusion: Considering Rate Locks
While locking in a rate around 7% might seem costly, considering the Fed’s potential actions and lender expectations, it could prevent future complications. Explore float down options tailored to your lender in the event of favorable changes in rates.
Understanding the financial landscape and rate options remains critical to navigating homebuying efficiently.
