Key Takeaways:
- A quoted rate is not necessarily locked. Check the Loan Estimate and written agreement.
- A lock has a deadline and conditions; changes to the application can matter.
- Ask about delays and extension costs before closing becomes urgent.
A report saying mortgage rates fell last week does not establish the terms of your loan. Once you are comparing an actual offer, the practical questions are whether the rate is locked, what that agreement covers and whether it lasts until your expected closing.
This U.S. checklist focuses on the lock agreement. It does not predict rates or recommend locking on a particular day.
Find the written confirmation
The CFPB rate-lock explanation says a lock generally preserves the rate between the offer and closing if you close within the specified period and the application does not change. Page one of the Loan Estimate indicates whether the rate is locked and until when.
Record the rate, loan amount, product, points or credits, expiration date and any applicable time zone. Keep the dated agreement with the estimate. If a phone conversation and document differ, ask the lender to reconcile them in writing.
Do not treat a reassuring verbal phrase such as “we have your rate” as a complete description of the terms. Ask what has actually been agreed and which document records it.
Compare the lock period with the real closing plan
Place the expected closing date beside the expiration. Then list unfinished steps and who is responsible for each one. An appraisal, document request or changed contract date may affect the timetable.
For a fictional example, a lock ends on the 18th but closing is moved to the 23rd. Identify that five-day gap promptly. Do not assume the lender must extend the agreement for free or that a seller’s schedule automatically changes your financing terms.
Ask about the cost of a delay
Request the extension policy, any charge, the calculation method and what happens if the lock expires. Ask who can authorize a change and what must happen before the deadline. Costs and available options vary; use the actual written offer.
If an extension were quoted at $450 in a fictional case, add it to the comparison as a specific possible cost. That amount is not a typical fee or an estimate for your lender. Compare it with the consequences of the other available options rather than looking only at the headline interest rate.
Understand which changes need a fresh explanation
The CFPB notes that changes involving the loan, down payment, appraisal, credit or verified income can affect a locked rate. Tell the lender about relevant changes and ask for the effect before assuming the earlier terms still apply.
Also ask what happens if market rates decline. Do not assume the lock includes a right to obtain a lower rate. Get any available adjustment policy, conditions and fees in writing.
Check the Closing Disclosure against the agreement
The CFPB guidance on changed rates and fees recommends asking the lender for a specific reason when terms differ. Keep the earlier estimate, lock confirmation and explanation together.
If an important issue remains unresolved, seek appropriate advice before signing. A late change may require reviewing financing and contract implications; a general article cannot determine your rights or the best alternative.
