Most mortgage pre-approval letters are valid for 60 to 90 days, though some lenders set shorter windows of just 30 days. The exact timeframe depends on the lender and is printed on the letter itself. If your pre-approval expires before you find a home, you can renew it, but the process may require updated documents and a new credit check.
Why Pre-Approvals Expire
A pre-approval is a snapshot of your financial health at a specific moment. Your lender reviewed your income, debts, assets, and credit score, then determined how much you could borrow based on those numbers. Over time, any of those factors can change. You might take on a car payment, switch jobs, or see your credit score shift. Lenders set expiration dates because the older that snapshot gets, the less reliable it becomes as a predictor of your ability to repay.
The Consumer Financial Protection Bureau notes that lenders typically check your credit before issuing a pre-approval and attach an expiration date of 30 to 60 days. In practice, many lenders extend that to 90 days, but you should check the date printed on your letter rather than assuming you have a full three months.
Pre-Approval vs. Final Loan Approval
These are two different stages, and each has its own clock. A pre-approval happens before you make an offer on a house. It tells sellers you’re a serious, qualified buyer. Final loan approval (sometimes called “clear to close”) happens after underwriting reviews the specific property you’re buying, your appraisal, title search, and all supporting documents. Final approval is tied to your closing date and generally stays valid only until that date passes.
If your closing gets delayed for any reason, your lender may need to re-verify your employment, pull updated bank statements, or run a new credit check before funding the loan. The further past the original closing date you drift, the more paperwork you may need to provide again.
Rate Locks Run on a Separate Timer
Your interest rate lock is not the same thing as your pre-approval. A rate lock is a lender’s guarantee that your interest rate won’t change for a set number of days, typically 30 to 60 days from when you lock it in. The lock period usually runs from initial approval through closing.
If closing takes longer than expected and the rate lock expires, your rate will float with daily market movements. That can work in your favor if rates drop, but it can also mean a higher rate and a bigger monthly payment. If your lock is about to expire, contact your lender before the expiration date to ask about an extension. Extensions are common, though some lenders charge a fee for them, often a fraction of a percentage point of the loan amount.
What Can Void Your Approval Early
An expiration date is not the only way to lose a pre-approval. Certain financial changes can effectively cancel it before the stated deadline, because they alter the assumptions the lender used when approving you. The changes that put your approval at risk include:
- Taking on new debt. Financing a car, opening a new credit card, or co-signing someone else’s loan increases your debt-to-income ratio, which is one of the core metrics lenders use.
- Missing debt payments. Even one late payment can ding your credit score and signal higher risk to the lender.
- Making large withdrawals. Draining your savings or moving large sums between accounts without a clear paper trail can raise questions during underwriting.
- Changing jobs. Even a promotion or a move to a higher-paying role can complicate things if it changes your pay structure (for example, from salaried to commission-based) or creates a gap in employment history.
- A drop in your credit score. Lenders typically pull your credit again right before closing. If your score has fallen significantly since the pre-approval, the loan terms could change or the approval could be withdrawn entirely.
The safest approach between pre-approval and closing is to keep your financial picture as stable as possible. Avoid large purchases, don’t open or close credit accounts, and stay in your current job if you can.
How to Renew an Expired Pre-Approval
If your pre-approval lapses before you’re under contract, you can renew it. Going back to the same lender is usually the fastest route. You can typically apply by phone or online, and you may not need to resubmit basic information the lender already has on file. That said, the lender will likely run another hard credit inquiry and ask for updated financial documents: recent pay stubs, bank statements, and possibly a new tax return if you’ve crossed into a new tax year.
Each hard credit inquiry can lower your credit score by a few points. However, credit scoring models generally treat multiple mortgage inquiries within a short window (usually 14 to 45 days, depending on the model) as a single inquiry. If you’re shopping multiple lenders, try to cluster your applications within that window to minimize the impact.
Renewal is also a good time to reassess. If interest rates have moved significantly since your original pre-approval, the amount you qualify for may have changed. Higher rates reduce your buying power because more of each monthly payment goes toward interest, leaving less room for principal. A lender who approved you for $400,000 at a lower rate might approve you for less at today’s rate, or the monthly payment at the original amount might stretch beyond your comfort zone.
Timing Your Pre-Approval Strategically
Since the clock starts ticking the day the letter is issued, getting pre-approved too early can mean going through the process twice. If you’re just beginning to browse listings and don’t plan to make an offer for several months, hold off. A good rule of thumb is to get pre-approved when you’re ready to start making offers within the next one to two months.
On the other hand, waiting too long can put you at a disadvantage in a competitive market. Sellers and their agents take pre-approval letters seriously. An offer without one is easy to overlook when other buyers come prepared. If you find the right home and your letter has expired, you may lose valuable time while scrambling to renew.
If your housing search is likely to take longer than 90 days, plan on renewing at least once. Keep your financial documents organized and accessible so the renewal process is quick. Having your two most recent pay stubs, two months of bank statements, and your latest tax return ready to upload can shave days off the turnaround.
