What this document can tell you
A rate lock protects specified pricing for a stated period only when its conditions remain satisfied. Get the lock terms in writing and match the expiration to a realistic closing schedule.
Your reading route
Confirm whether the rate is actually locked
Check the rate-lock field on page one of the Loan Estimate and obtain the separate lock confirmation when provided. Record the rate, points, lender credits, lock date, expiration date and time zone. A quote, application or Loan Estimate with an unlocked rate is not the same as a completed lock agreement. Next step: Compare the complete offers around the lock.
Ask which application changes can reprice the loan
A lock generally assumes the stated loan amount, product, property, occupancy, down payment, credit and verified income remain consistent. Ask for the lender's change rules in writing. A new loan request, appraisal result or material change in documented information can affect pricing even during the lock period. Next step: Trace points, credits and compensation.
Match the lock period to the closing path
Work backward from the contract closing date and include appraisal, underwriting, conditions and document preparation. A shorter lock may cost less but leaves less margin. Ask who monitors the deadline, when an extension decision is made and whether delays attributable to the lender are treated differently. Next step: Verify a broker before sharing documents.
Price extensions and float-down features before relying on them
The Loan Estimate can show that a rate is locked without stating every extension cost or alternative lock-period price. Ask for extension terms, cost allocation and any float-down option before the deadline. Treat a verbal promise as unresolved until it appears in the lender's written policy or confirmation. Next step: Ask how refinance delays affect the lock.
Review the final pricing before sending funds
Compare the Closing Disclosure rate, points and lender credits with the locked terms. If they differ, request the specific reason and supporting changed circumstance. Do not wait until the signing table to question a material difference. Next step: Check final pricing before closing.
Follow one detail through the document
A purchase is scheduled to close in 38 days, but the offered lock lasts 30 days. The borrower requests both 30-day and 45-day pricing plus written extension rules. The longer lock costs more upfront but removes a known timing mismatch; the decision is based on the closing path rather than a lower headline rate.

Questions about the document
Can a locked mortgage rate still change?
It can when material application details change or the lock conditions are not met. Ask the lender for the applicable written policy and an explanation tied to your specific change.
Does the Loan Estimate show extension cost?
It shows lock status and timing, but it may not state every extension cost or alternative lock-period price. Ask for those details before choosing the lock.
Finish the review
- Obtain written lock confirmation
- Record rate, points, credits and expiration
- List changes that permit repricing
- Compare lock periods and costs
Manage the lock as a dated agreement
A rate lock is a time limited commitment tied to stated loan and property facts. Record the rate, points or credits, lock date, expiration and change conditions in writing. Then manage the application calendar so avoidable delays do not turn the lock into an urgent and expensive closing decision.
Confirm what is locked and what is not
Ask whether the rate is floating or locked and obtain the written confirmation. Record the loan amount, product, property, occupancy, credit assumptions, points or lender credits and lock period. Ask whether an application change, lower appraisal, unverifiable income or product switch could change the terms, and how you will receive a revised disclosure.
Build a contingency calendar before expiration
Work backward from closing and the lock expiration. Add dates for appraisal, document delivery, underwriting conditions, insurance and final disclosure review. Ask who monitors the lock, when an extension decision must be made, what each extension period costs and who pays when the delay is attributable to the lender, broker or borrower. Keep all answers with the lock confirmation.
