With mortgage rates rising, is now a good time for you to buy a home?
Data from the Optimal Blue Market Advantage report shows total mortgage rate-lock volume across the United States fell 2% in September 2026. This downward trend reflects a cooling period for overall mortgage activity as families navigated changing market conditions.
Why it matters
The persistent decline in rate locks suggests a shifting landscape for homeowners and buyers facing sustained interest rate pressure. While overall volume dropped 26% year over year, the niche non-QM market bucked this trend by expanding during the same period.
Total mortgage rate-lock volume declined 2% month over month and 26% year over year in September 2026. During that same period, non-QM loans grew to represent 12% of total mortgage production.
The players

The details
The report highlights a broader contraction in standard mortgage activity, with total lock volume down 21% over the past three months. Conversely, non-QM lending, which provides financing for borrowers who may not meet traditional qualification criteria, expanded by 8% in September. This movement suggests that some buyers are increasingly looking toward alternative financing products to complete transactions despite the challenging rate environment.
Timeline
September 2026 marked the primary period for the mortgage data report.
The Home Front
The divergence between falling total locks and rising non-QM volume highlights a growing reliance on alternative financing tools in a restrictive lending climate. This shift follows long-term trends identified by the Optimal Blue Market Advantage report tracking national mortgage activity.
If you are currently house hunting, consider meeting with a licensed mortgage broker to discuss whether non-QM products might be a viable alternative to conventional financing. Monitor your local interest rate environment closely before locking in any rate, as market volume remains highly volatile.
The takeaway
While standard mortgage activity has slowed significantly, the rise of non-QM loans indicates that financing options remain available for various borrower profiles. Consult with a qualified financial advisor to evaluate how different loan types could impact your household budget and long-term goals.
