What the lock-or-float call really depends on

The market direction above is only half of it. The right call also depends on how close you are to closing, whether a high-impact release lands before then, and your lender's reprice behavior. That is exactly what Lock Radar personalizes. The read here is general market commentary to frame the decision, not a recommendation for your specific loan.
