Suppose you have a $400,000 30-year loan locked at an illustrative 6.25%, and the lock lapses while market pricing has moved up 0.375 point to 6.625%. The principal and interest payment goes from about $2,463 to about $2,561. That is roughly $98 more per month, or about $5,900 over five years, before counting any change in points or credits. These rates are illustrations, not current quotes.
A lapsed lock does not automatically mean you lose your rate, and you usually have more than one way to handle it. This guide from Duane Buziak, NMLS #1110647, walks you through confirming where you stand, pricing your options, and keeping the closing on track. Before you start, gather three documents: your rate lock confirmation, your Loan Estimate, and the closing date from your purchase contract.

Step 1: Confirm Whether Your Lock Has Actually Expired
Find your lock confirmation and read three fields: the lock date, the lock period in days, and the expiration date. Lock periods count calendar days, weekends and holidays included, so a 30-day lock is not 30 business days. Some lenders also apply a cutoff time on the expiration date, so verify the exact deadline with your lender rather than assuming midnight.
Next, email your loan officer. A written question leaves a record, and it forces a precise answer. Ask:
- Is my lock expired, or does it expire within the next few days?
- What is your policy on extensions and relocks, and what does each cost?
- What is the current expiration date, and what closing date does the lender expect?
The distinction matters. An expired lock has already lapsed and the lender’s relock policy applies. A lock that merely will lapse before closing is still active, which means an extension is usually available and often cheaper if you ask before the deadline.
The most common mistake is assuming the lock runs until the closing date on your purchase contract. It does not. A rate lock runs on its own clock, started when you or your loan officer locked, and the contract date has no effect on it. If the lock confirmation says 45 days and the closing slips to day 52, you have a gap, even if everything else is on schedule.
Step 2: Find Out Why the Closing Slipped
The cause of the delay shapes who should pay for fixing it. Common causes include:
- An appraisal that came back late or needs a review
- Underwriting conditions that arrived late in the process
- Borrower documents that are missing or out of date
- Title or survey problems
- A backlog on the lender’s side
Lenders often treat delays on their own side differently from delays caused by the borrower or the seller. Ask directly: “If the delay is on the lender’s side, will you absorb the extension cost?” Policies vary by lender and investor, so do not assume an answer either way. Asking costs nothing, and a documented lender-side delay gives you a stronger position.
Then build a short working list of every open condition. For each one, write down who owns it and the date it will be resolved. For example:
- Appraisal report: lender, expected date
- Updated pay stub and bank statement: you, date you will upload
- Title commitment correction: title company, expected date
- Final underwriting review: lender, expected date after the above clear
Ask your loan officer to confirm the list, then ask for a realistic new closing date. Do not pick an option in Step 3 until you have that date. The length of the gap is what decides whether an extension, a relock, or something else makes sense, and a date that is too optimistic is how people end up buying a second extension.
Step 3: Compare Your Three Options: Extend, Relock, or Float
Each option has its own meaning, cost structure, and risk:
- Extension: you pay a fee to keep your original rate for additional days. Lenders commonly price this as a fraction of the loan amount per day or per block of days, but the schedule varies by lender, so ask for it in writing.
- Relock: you set a new lock at current market pricing. The result can be better or worse than your original rate.
- Float: you leave the loan unlocked and the rate moves with the market, usually daily.
Many lenders apply a “worse of” rule to relocks, meaning you receive the lower of the original and current pricing quality only in one direction: if the market is worse, you take the worse rate, and if the market is better, you may not be allowed to capture the improvement. Others reprice at current market without conditions. Policies differ by lender and investor, so ask which one applies to you and whether a waiting period follows an expiration.
| Option | What it costs | Rate outcome | Risk | Fits when |
|---|---|---|---|---|
| Extend | A fee set by your lender, usually tied to loan amount and number of days | Original rate held | Fee is lost if closing slips again; may need a second extension | Market has moved up and the new closing date is close and reliable |
| Relock | Possibly no fee, but repricing at current market and lender policy | Could be higher or lower; depends on the lender’s rule | Pricing may be worse than the original lock | Market is flat or lower than your original rate, or the lock has already lapsed |
| Float | No lock fee | Changes with the market, day to day | Rate can rise before you lock, with no cap | Rarely, and only when the closing date is flexible and you can absorb a higher payment |
One mistake to avoid: floating in the hope that rates will fall when your closing date is fixed. A contract deadline means you cannot wait for a better day, and you hold all the downside of a rate increase with a limited window to act.
Step 4: Price the Extension Against the Rate Difference
Break-even math turns this from a guess into a decision. Divide the extension fee by the monthly payment savings from holding your original rate. The result is the number of months it takes for the extension to pay for itself.
Reuse the opening example. Holding the 6.25% rate instead of repricing to 6.625% saves about $98 per month on a $400,000 loan. Suppose, purely as an illustration, your lender quotes a $1,000 extension fee. Divide $1,000 by $98 and you get about 10 months to break even. If you expect to keep the loan for five years, you would capture roughly $5,900 in lower payments for a $1,000 cost. Swap in your actual fee and your actual rate difference.
To see which way the market has moved since your lock date, check the Freddie Mac Primary Mortgage Market Survey weekly average. It is published weekly, so compare the latest reading as of October 2026 with the reading from your lock week. It is a national benchmark, not a quote, but it shows direction.
A workable decision rule: if the fee is less than the cost of the rate increase over the time you expect to keep the loan, extending usually wins. If the market is flat or lower, a relock often makes more sense, depending on the lender’s policy. Also ask:
- Can the fee be paid at closing instead of upfront?
- Can it be structured through a credit? No-out-of-pocket closing options exist in some scenarios, but they depend on the loan and the pricing, so ask whether yours qualifies rather than assuming.
- Does the fee apply toward closing costs or is it separate?
Step 5: Shop the Relock With an Independent Rate Comparison
If your lender’s relock price comes back higher than you expected, you are not obligated to accept it. A single-lender quote shows you one price from one set of pricing. An independent mortgage consultant can price the same scenario across hundreds of wholesale lenders and show you how the numbers compare. Duane Buziak can run that comparison without a credit hit and at no cost to you.
Timing is the catch. Switching lenders mid-process restarts underwriting and usually the appraisal, along with new disclosures and a new lock. That only makes sense if the closing is far enough out or the savings are large. Before you consider it, check two dates in your purchase contract: the closing date and the financing contingency deadline. If switching would push you past either date without an extension from the seller, the savings may not be worth the risk.
The structural difference between your options is simple:
- One-lender quote: a single set of pricing and a single policy for relocks and extensions. Large direct lenders, including Rocket, Movement, and Veterans United, price this way.
- Multi-lender comparison: the same borrower profile priced against many lenders at once, with each lender’s lock terms and fees visible side by side.
Neither approach is right for every file. A comparison is most useful when the gap between your lender’s relock price and the market is large, and when you have time to move.

Step 6: Protect Your Contract Deadlines and Your Credit File
Call your real estate agent now and ask about a written closing-date extension addendum. The contract should not lapse before the new lock does. Also check your financing contingency date, since it may expire before your closing date does and give the other side leverage if the loan is not clearly on track.
While the loan is in process, keep your file clean:
- No new debt, including car loans and store financing
- No large unexplained deposits, since underwriters will ask for a paper trail
- No job changes without telling your loan officer first
Also re-check expiration dates on the documents already in your file. Credit reports and pay stubs age out, and a re-pull can change your pricing if your score moved. Ask your loan officer which of your documents expire before the new closing date.
Loan size affects pricing, so confirm which side of the conforming limit you are on. The Federal Housing Finance Agency sets the limits each year, and for 2026 the baseline limit for a one-unit property is $832,750, with higher limits in designated high-cost counties, which include parts of Northern Virginia. Look up your county in the FHFA conforming loan limit tool and verify the figure for your property, since jumbo pricing works differently from conforming pricing.
Finally, know your paperwork. The Consumer Financial Protection Bureau explains how the Loan Estimate and the Closing Disclosure work, including which changes in your costs a lender may make after issuing the original. If a fee or rate changes, ask which changed circumstance the lender is relying on.
Step 7: Get the New Terms in Writing and Re-Lock Strategically Next Time
Once you have chosen, get a new lock confirmation and verify each term:
- The rate
- Points or lender credits
- The new expiration date
- Any extension or relock fee, and when it is charged
Then compare the revised Loan Estimate against the original line by line. If anything differs beyond what you agreed to, ask your loan officer to explain it in writing before you move forward.
Set a calendar reminder for seven days before the new expiration and ask your loan officer for weekly status updates until closing. A short weekly note listing open conditions and their dates is enough, and it keeps you from learning about a problem on day 29 of a 30-day lock.
If you are locking a rate again in the future, build in a cushion. Choose a lock period that runs beyond your expected closing date, since closings often slip by a few days or more. Compare the cost of longer locks, because longer periods often price slightly higher, although how much varies by lender and market. A modest premium for extra days may cost less than an extension, but price both options before you decide.
