If you want to know where mortgage rates are headed, watch the 10-Year Treasury yield.
When the yield dips below key support levels — like 4.00% — mortgage-backed securities often follow, and mortgage rates improve.
But breaking below 4.00% has been tough in 2025. Inflation is sticky, jobs data is resilient, and tariff headlines are pushing yields higher.
That’s why last week’s dip was so rare — and why we moved quickly to lock.
Our focus now is on staying ready for the next test of that 4.00% level. If it happens, the window could be very short.
