Confirm lock evidence
Obtain written confirmation showing the rate, points, lender credits, lock date, expiration date and loan program. Compare it with the revised Loan Estimate.
Record the locked package. Keep the rate, points or credits, loan type, lock date, expiration date and any property or underwriting assumptions together. A confirmation that says locked without those details is incomplete evidence.
If the locked offer changes the points charged for the rate, model the rate-and-points break-even over the period you expect to keep the loan.
Count backward from closing
Leave room for underwriting conditions, appraisal issues and document preparation. A lock that expires on closing day provides no cushion.
Build a delay map. Place appraisal, document, underwriting, condition-clearance and closing milestones against expiration. Identify which party controls each step and when an extension decision must be made before the lock lapses.
Price extensions in advance
Ask who pays when delay is caused by the lender, seller, borrower or outside event. Record extension cost and available durations.
Ask for extension scenarios. Request the cost and rate treatment for a short and longer extension, including what happens when the borrower, lender or outside event causes delay. Preserve the written answer before relying on a closing date.
Understand change triggers
Application changes, a missed lock deadline or a different loan program can affect pricing. Ask what facts would permit the locked terms to change.
Plan the float-down question
Some arrangements offer a limited benefit if rates fall; many do not. Get the eligibility, fee and comparison benchmark in writing.
Connect the lock expiration to the closing schedule
A rate lock is a dated agreement built on assumptions. Its practical value depends on what is covered, what can invalidate it and who bears the cost of delay.

Build the deadline file
Timing rights fail when the date, notice rule and delivery proof live in different places. Put them in one working file and calculate backward from the controlling event.
For this decision, the first working threshold is concrete: Written lock received; Expiration includes time zone; Closing cushion measured.
Read those checks beside the sections on Confirm lock evidence, Count backward from closing, Price extensions in advance. Completing one item does not cure a mismatch elsewhere, so leave the decision open until the record is internally consistent.
Assign every unresolved row an owner and a date for receiving the missing document so it cannot disappear in the rush to sign.
| Timing control | Record to preserve | Written confirmation |
|---|---|---|
| Written lock received | Mark the controlling page or source, its version date, the responsible party and any exception that changes the result. | Exactly what terms are locked? |
| Expiration includes time zone | Mark the controlling page or source, its version date, the responsible party and any exception that changes the result. | Who pays for an extension under each delay cause? |
| Closing cushion measured | Mark the controlling page or source, its version date, the responsible party and any exception that changes the result. | What changes can invalidate the lock? |
| Extension prices known | Copy the dollar amount or rate, its source page, what it includes and the condition that can change it. | Is there a float-down option? |
| Delay responsibility understood | Mark the controlling page or source, its version date, the responsible party and any exception that changes the result. | Exactly what terms are locked? |
| Revised disclosure checked | Mark the controlling page or source, its version date, the responsible party and any exception that changes the result. | Who pays for an extension under each delay cause? |
Calendar an earlier personal deadline when delivery or processing time matters. Keep the notice and proof together instead of relying on a sent-message screen alone.
