A mortgage rate lock holds the rate in your lender’s offer for a defined period, subject to the lock agreement’s terms. If market rates fall after you lock, your rate usually does not fall automatically; ask whether your lender offers a float-down and what conditions apply. Start by checking your Loan Estimate and lock agreement for the lock status, expiration date and time, and any contingencies.
What happens if I lock my rate and interest rates go down?
Unless your lock agreement provides a way to take a lower rate, a market decline does not automatically change the rate you locked. A float-down may let you benefit from a lower rate during the lock period, but it is not a standard feature with universal terms. Ask your lender what is available for your particular loan and get the answer in writing.

The Consumer Financial Protection Bureau (CFPB) describes a rate lock as protection against a rate change between the offer and closing, provided you close within the specified timeframe and there are no changes to your application. Its consumer guidance, last reviewed May 2, 2023, says locks are commonly available for 30, 45, or 60 days, sometimes longer. Those are typical periods, not a required term or a guarantee that a particular lender will offer them. The CFPB explains how a mortgage rate lock works.
So if you see rates fall, the useful question is not simply “Are rates lower now?” It is: “Does my agreement let me use a lower rate, and what would I have to give up or pay to do so?” The lender’s current pricing, your eligibility, and the agreement determine the answer.

What should I check in my Loan Estimate and lock agreement?
Verify that the rate is actually locked, when the lock ends, and what conditions could affect it. Do this before relying on a quoted rate or trying to compare it with a new offer.
- Lock status: Find the rate-lock status on the Loan Estimate. A quoted rate is not necessarily a locked rate.
- Expiration date and time: For a locked rate, the Loan Estimate must identify the date and time the lock period ends. Check the exact deadline rather than assuming the lock lasts through your closing date.
- Agreement terms: Read the accepted or signed lock agreement for its contingencies, including any rules for extending the lock or requesting a float-down.
- Loan details: Check that the loan type, amount, down payment, and other application details match the assumptions behind the offer.
The disclosure requirement is in Regulation Z’s Loan Estimate rule. The Loan Estimate gives you a key status and deadline; the lock agreement supplies the applicable terms and contingencies. If something is unclear, ask the lender to explain it rather than assuming that an informal quote overrides the written documents.

Possibly. Some lenders offer a float-down, which may let a borrower take advantage of a lower rate during the lock period, but availability and terms vary. Freddie Mac describes the option as one some lenders may offer and cautions that its terms and availability vary. Freddie Mac’s rate-lock guidance does not establish a universal trigger, fee, or eligibility rule.
Ask the lender these questions before assuming a float-down will help:
Also popular on Amazon
- Is a float-down available for my specific loan and lock?
- When can I request it, and how many times, if at all?
- What qualifies as a sufficient rate decrease, and how does the lender determine the rate that applies?
- Is there a fee or another condition? Would the points, lender credits, or other pricing change?
- Does requesting it affect the lock’s expiration date or the lender’s ability to close on time?
Get the answers in writing, including the rate and any points or credits that would apply. A lower advertised rate alone does not show that your loan can be repriced or that the overall offer would be better. No single standard float-down threshold or cost applies, so those details must come from your lender’s current written terms.
What if my rate lock expires before closing?
If closing may happen after the lock expires, ask the lender about an extension and its cost before the deadline. An extension is not necessarily free or guaranteed. Without an extension, you may be exposed to the rate then available, depending on the lender’s terms.
Freddie Mac notes that a longer lock may cost more, while the CFPB advises borrowers to ask about the cost of extending a lock. Your lender’s agreement and written extension policy control the specifics. Ask for the price, any conditions, and the new expiration date in writing, then compare that cost with the timing and pricing consequences of letting the lock expire.
When you ask, also confirm what is causing the delay and whether the lender can still close by the proposed new date. The practical risk is not only the extension charge: a missed deadline can leave you without the rate you expected, while switching lenders could require additional processing time. Do not assume that a lock will be extended automatically just because a closing delay is outside your control.

Can changes to my application affect a locked rate?
Yes. A lock does not necessarily preserve the original rate if key application details change or the lock expires. CFPB examples include changes to the loan type or amount, down payment, appraisal results, credit score, or your ability to document income.
If the lender says the rate has changed, ask for the specific reason and how it relates to the lock agreement and your application. A changed circumstance is not a reason to guess at the result: have the lender explain what changed, which lock term applies, and what options remain. Keep copies of the Loan Estimate, lock agreement, any revised disclosures, and written explanations so you can compare the timeline and terms.
If the Closing Disclosure shows a different rate from the one on the Loan Estimate, ask the lender promptly for the reason and compare it with your lock agreement and any changes to your application. The CFPB’s guidance on rate or fee differences between a Loan Estimate and Closing Disclosure recommends contacting the lender to understand the change.
Should I switch lenders if another offer has a lower rate?
A lower headline rate is not enough to decide. Compare written offers for the same loan type and terms, including the rate, points, lender credits, lock details, extension terms, any float-down, and the lender’s realistic ability to close on time.

Use the Loan Estimates to compare the offers on equal terms. Ask each lender how the price changes with a different lock length, and whether the quoted rate is locked. The CFPB provides tools for reviewing Loan Estimates and choosing a loan offer.
A lender change also has timing and process consequences: the new lender needs to complete its own steps before closing, and the existing lock may not carry over. Weigh those consequences and any costs against the full written offer, not just its rate. The CFPB says a borrower may choose another lender if the rate or fees change significantly and the lender cannot offer an acceptable resolution. That is an option, not a guarantee that switching will be practical or less expensive for every borrower.
What should I do now if market rates have fallen?
Work from the documents and deadlines, then get the lender’s options in writing. These steps help you distinguish a real available choice from a market-rate headline:
- Find both documents. Locate the Loan Estimate and the accepted or signed lock agreement. Confirm the status, expiration date and time, and contingencies.
- Ask about a float-down. Ask whether one applies to your loan, what rate decrease qualifies, when you can request it, and whether fees or pricing terms change.
- Protect against a closing delay. If timing is uncertain, request the extension policy, price, conditions, and revised deadline in writing before the lock expires.
- Compare any new offer fairly. Get a written Loan Estimate for the same loan type and terms. Compare points and credits, lock details, costs, and closing timing as well as the rate.
- Question an unexpected change. If the lender reprices the loan or the Closing Disclosure shows a different rate, ask for the precise reason and compare it with the agreement and any changed application information.
No single path—keeping the lock, requesting a float-down or extension, or considering another lender—is right for every borrower. Lock terms, lender pricing, eligibility, and closing schedules vary, so use the written terms for your loan rather than assuming a policy applies everywhere.

Frequently Asked Questions
Will my locked rate change just because the Federal Reserve cuts rates?
Not automatically. A change in a benchmark or market rates does not by itself revise your mortgage lock; any lower rate depends on the lender’s pricing and the options in your agreement.
What if I cannot find a signed rate-lock agreement?
Ask the lender to confirm in writing whether your rate is locked and to provide the applicable lock terms. Check the Loan Estimate’s lock status and deadline, but do not treat a rate quote alone as proof of a lock.

No. A rate lock addresses the rate for a specified period and under stated conditions; it does not itself guarantee closing. Confirm the lender’s timeline and raise likely delays early so you can discuss an extension before expiration.
