A bank can revoke a mortgage, but only in specific situations. Before closing, a lender can withdraw a commitment letter if your finances change, the appraisal comes in low, the title has problems, or you miss required documentation. After closing, the loan is a binding contract, and the lender’s main routes to unwind it are borrower fraud, default followed by acceleration and foreclosure, or an unauthorized transfer of the property that triggers a due-on-sale clause.
Before Closing: When a Lender Can Walk Away
The window between your commitment letter and the closing table is where most loans fall apart. A commitment letter is a conditional approval, not a guarantee, and the conditions do real work.
Lenders run a final check right before closing. They re-verify employment and pull a fresh credit report. If you lost your job, moved to a lower-paying position, or took on new debt like a car loan or store financing, your debt-to-income ratio shifts and the lender can pull the offer. A meaningful drop in your credit score between approval and closing has the same effect. This is why real estate agents warn buyers not to make big financial moves after preapproval.
Property problems cause just as many withdrawals. If the home appraises for less than the purchase price, the lender will not fund a loan for more than the property is worth. You can renegotiate with the seller, cover the gap yourself, or walk away.1Consumer Financial Protection Bureau. My Appraisal Is Less Than the Sale Price – What Does That Mean for Me? A title search that turns up unresolved liens or an ownership dispute can also make the property unfundable.
Your commitment letter lists documents you have to provide before closing, like updated pay stubs or bank statements. Miss those deadlines and the lender has a contractual right to withdraw.
Commitment Letters and Rate Locks Expire
Every mortgage commitment carries an expiration date, typically 30 to 45 days from issue. If closing drags past that window, the lender no longer has to honor the original terms. Your locked interest rate floats back to whatever the market rate is on the day you try to close.
Most lenders will extend an expiring commitment for a fee, usually between 0.25% and 1% of the loan amount, though some charge a flat fee. If the lender caused the delay, many waive the charge. If you caused it, expect to pay. When a commitment expires without an extension, the lender can require you to reapply, submit fresh documentation, and requalify at current rates.
Getting Your Earnest Money Back
When a lender pulls a loan before closing, the purchase usually collapses with it. Whether your deposit comes back depends on the contingencies in your purchase contract.
A financing contingency makes the sale conditional on you securing a mortgage. If the lender withdraws and you have this contingency in place, you get your earnest money back. An appraisal contingency works the same way: if the home appraises below the purchase price and you cannot bridge the gap, you can exit without losing the deposit.
Without those contingencies, the seller generally keeps your earnest money. Buyers in competitive markets sometimes waive contingencies to strengthen their offer. If the loan then falls through, that deposit is usually gone.
Your Right to a Written Reason
If a lender revokes your mortgage, federal law requires them to tell you why. Under the Equal Credit Opportunity Act, a lender that takes adverse action on a completed application must send written notice within 30 days. The notice has to give specific reasons for the denial or revocation, not vague language about internal standards.2Consumer Financial Protection Bureau. 12 CFR Part 1002 (Regulation B) – Notifications
If the decision relied on your credit report, the notice must also include your credit score and the key factors that affected it.3Federal Trade Commission. Using Consumer Reports for Credit Decisions: What to Know About Adverse Action and Risk-Based Pricing Notices That detail tells you what to fix before applying elsewhere. If you believe the lender discriminated based on race, sex, marital status, age, or income source, the notice explains how to file a complaint with the appropriate federal agency.
After Closing: Fraud Can Undo the Loan
Once a mortgage closes, undoing it is rare. The main exception is fraud. If the lender discovers you lied on your application, the entire loan can be called in, meaning the full balance becomes due immediately.
Application fraud covers a lot of ground: inflating your income, fabricating employment, hiding debts, or lying about the source of your down payment. Occupancy fraud is another common form. Borrowers who say a property will be their primary residence qualify for lower rates and smaller down payments. If you actually plan to rent it out or use it as a second home, that misrepresentation can unravel the loan when the lender’s quality control review catches it.
The fallout goes beyond losing favorable terms. Federal bank fraud carries penalties of up to $1,000,000 in fines, up to 30 years in prison, or both.4Office of the Law Revision Counsel. 18 USC 1344 – Bank Fraud Even without prosecution, the lender can sue civilly to recover losses and will report the fraud to credit bureaus, effectively locking you out of financing for years.
Default, Acceleration, and Foreclosure
The most common way a bank ends your rights to a property after closing is foreclosure, and it does not happen fast. Federal law prohibits your loan servicer from starting the foreclosure process until you are more than 120 days behind on payments.5eCFR. 12 CFR 1024.41 – Loss Mitigation Procedures That four-month window exists so you can catch up or explore alternatives.
Before accelerating, the servicer has to send a breach letter explaining what you defaulted on, what you need to do to fix it, and the deadline to cure. For conventional loans, that letter must go out no later than the 75th day of delinquency.6Fannie Mae. Sending a Breach or Acceleration Letter Cure the default before the deadline and the servicer loses the right to accelerate based on that breach.
Missed monthly payments are the obvious trigger, but not the only one. Your mortgage requires you to keep up with property taxes and homeowners insurance. Fall behind on either and the lender’s collateral is at risk, because a government tax lien outranks a mortgage lien. The servicer will typically pay the overdue amount and add it to your balance. If your insurance lapses, the servicer can also buy force-placed coverage on your behalf and charge you for it, which is almost always more expensive than a policy you would buy yourself and protects only the lender.7eCFR. 12 CFR 1024.37 – Force-Placed Insurance If those charges push your loan into delinquency, foreclosure can follow.
Slowing Foreclosure Through Loss Mitigation
Federal law gives you a real tool to slow or stop foreclosure, but you have to use it. If you submit a complete loss mitigation application before the servicer files the first foreclosure notice, the servicer cannot begin foreclosure until it reviews your application, notifies you of the decision, and any appeal period expires.5eCFR. 12 CFR 1024.41 – Loss Mitigation Procedures
Even after foreclosure has started, submitting a complete application more than 37 days before a scheduled foreclosure sale forces the servicer to halt. The servicer cannot move for a foreclosure judgment or hold the sale while your application is under review. Options can include loan modifications, repayment plans, forbearance, or short sales. The application has to be complete to trigger these protections.
Curing or Reinstating After Acceleration
When a lender “calls in” a mortgage, it is invoking an acceleration clause: instead of monthly payments over 15 or 30 years, the full remaining balance becomes due. Acceleration is a choice, not automatic, and most lenders will not invoke it unless you have been delinquent for months without responding.
Acceleration can also be undone. Cure the default before the lender formally invokes the clause and the lender loses the right to accelerate on that breach. Even after acceleration, many jurisdictions let you reinstate the loan by paying all missed payments plus late fees, attorney costs, and any other charges the lender incurred. Reinstatement puts you back on the original payment schedule. State law and your mortgage terms control how long you have, so the deadline varies, but the option exists in most places.
Transferring the Property: The Due-on-Sale Clause
A due-on-sale clause lets the lender demand full repayment if you transfer ownership of the property without permission. It is a standard provision in conventional mortgages, and federal law explicitly allows enforcement.8Office of the Law Revision Counsel. 12 USC 1701j-3 – Preemption of Due-on-Sale Prohibitions You cannot sell your home or transfer the title and leave the old mortgage in place for someone else to pay. If you transfer without satisfying the loan, the lender can accelerate the balance, and if you cannot pay, foreclosure follows.
Federal law carves out several transfers where the lender cannot enforce the clause on residential properties with fewer than five units:8Office of the Law Revision Counsel. 12 USC 1701j-3 – Preemption of Due-on-Sale Prohibitions
- A transfer that happens automatically when a joint tenant or co-owner with survivorship rights dies.
- A transfer to a relative after the borrower’s death.
- A transfer where the borrower’s spouse or children take ownership.
- A transfer to a spouse under a divorce decree or separation agreement.
- A transfer into a living trust where the borrower remains a beneficiary and no one’s right to live in the property changes.
- Granting a subordinate lien like a second mortgage or home equity line that does not involve transferring occupancy rights.
- Granting a lease of three years or less with no purchase option.
- Purchase-money security interests for household appliances.
The living trust exception is the one that most often catches homeowners off guard. Estate planners routinely recommend transferring a home into a revocable living trust to avoid probate, and borrowers worry this will trigger acceleration. It will not, as long as you stay a beneficiary and do not change who has the right to live in the property.
