How Long Is Mortgage Pre-Approval Good For? (2026)

in :

Most mortgage pre-approval letters expire in 60 to 90 days. If you are not under contract before the clock runs out, you will need to reapply — but with the right timing strategy, that is easy to avoid.

Standard Pre-Approval Validity Window

Most mortgage pre-approval letters are valid for 60 to 90 days from the date the lender issues the letter. The exact duration varies by lender — some issue 30-day letters, while others go as long as 120 days. The expiration date is stated on the letter itself.

After a pre-approval expires, the lender considers your financial information stale and will require a full re-application — updated documents, a fresh credit pull, and a new underwriting review — before issuing a new letter. See our full checklist of documents needed for mortgage pre-approval so you are ready to move quickly.

Why Do Pre-Approvals Expire?

A pre-approval is a snapshot of your financial health at a specific point in time. Lenders set expiration dates because several key inputs can change:

  • Credit score — Opening new accounts, taking on debt, or missing payments can lower your score.
  • Income — A job change, reduced hours, or loss of employment changes your qualifying income.
  • Interest rates — Rates quoted during pre-approval may no longer be available, altering what you can afford.
  • Asset balances — The funds verified for your down payment need to still be in your account.
  • Debt levels — New loans or increased credit card balances change your debt-to-income ratio.

Use our debt-to-income calculator to monitor your DTI throughout your home search so you are never caught off guard at renewal time.

What Can Void a Pre-Approval Before It Expires?

Even within the validity window, certain events can make your pre-approval invalid:

  • Job loss or change: Losing your job or switching to a different field (or from employed to self-employed) is the most common disqualifier. Lenders re-verify employment before closing.
  • Taking on new debt: Financing a car, opening new credit cards, or co-signing a loan increases your DTI and can push you out of qualifying range.
  • Credit score drop: A score drop of even 20 points can shift you into a higher rate tier or below the minimum threshold for the loan type you were approved for.
  • Large undisclosed deposits: Unusual deposits in your bank accounts that cannot be sourced will require explanation. If the source turns out to be a loan, it affects your DTI.
  • Property doesn’t appraise: If the home’s appraised value comes in below the purchase price, your loan amount may need to change — potentially requiring a new pre-approval at a different amount.

How to Renew a Pre-Approval

Renewing a pre-approval is straightforward but involves real work:

  1. Contact your loan officer before the expiration date — ideally 1 to 2 weeks before.
  2. Provide updated income documents: most recent pay stubs, updated bank statements, and any new tax returns if the filing year has changed.
  3. Authorize a new credit pull. This is a hard inquiry but will have minimal score impact if you are already in an active home search.
  4. Receive a new pre-approval letter with a new expiration date.

If rates have changed significantly since your original pre-approval, use the renewal as an opportunity to re-shop other lenders. Our guide on how to compare mortgage lenders walks through exactly what to evaluate. You can also run side-by-side scenarios with our mortgage comparison calculator.

When Is the Best Time to Get Pre-Approved?

The ideal timing is 30 to 60 days before you expect to start making offers on homes. This gives you:

  • Enough runway to fix any issues uncovered during the application process.
  • A valid letter ready to attach to your offer without needing to rush a renewal.
  • Time to comparison-shop two or three lenders without feeling pressured.

Getting pre-approved too early — six months before you are ready to buy — means you will likely need to renew at least once, subjecting yourself to a second credit inquiry and additional paperwork.

Pre-Approval vs. Pre-Qualification: A Quick Reminder

A pre-qualification is an informal estimate based on self-reported information. No hard credit pull. No document verification. Sellers do not treat it as a serious commitment.

A pre-approval involves a hard credit inquiry, income and asset document review, and a conditional lending commitment. It is what sellers and their agents expect before accepting an offer in competitive markets.

Pre-Approval and Rate Locks

A pre-approval letter does not lock your interest rate. Rates are only locked after you are under contract and choose to lock with a specific lender. Rate locks typically last 30 to 60 days — enough time to get through underwriting and close. If your rate lock expires before closing, you may need to pay a fee to extend it.

Use our mortgage calculator to model how different interest rates affect your monthly payment, so you understand the stakes when rate-shopping.

What to Do During Your Pre-Approval Window

While your pre-approval is active, protect it:

  • Do not apply for any new credit (credit cards, auto loans, personal loans).
  • Do not co-sign any loans.
  • Do not make large non-payroll deposits without keeping documentation of the source.
  • Do not change jobs without first speaking with your loan officer.
  • Do not make large purchases on existing credit cards.

Frequently Asked Questions

Does a pre-approval guarantee I will get the loan?

No. A pre-approval is a conditional commitment, not a guarantee. Final approval happens after the property is appraised, your file is fully underwritten, and any conditions are cleared. Changes to your financial profile between pre-approval and closing can result in denial.

Can I get pre-approved by multiple lenders?

Yes, and you should. Shopping multiple lenders within 45 days counts as one credit inquiry under FICO rules. Comparing Loan Estimates from two or three lenders can save thousands over the life of the loan.

Can I use a pre-approval letter from one lender to close with another?

No. The pre-approval letter is specific to the lender who issued it. If you switch lenders after going under contract, the new lender will issue their own approval after reviewing your file.

What documents do I need to renew my pre-approval?

Updated pay stubs (last 30 days), updated bank statements (last 2 months), and authorization for a new credit pull. If it has been more than a year since your last tax return was filed, you may also need to provide the new year’s return. See our pre-approval document checklist for the full list.

How fast can I get pre-approved?

With complete documents, many lenders can issue a pre-approval within 1 to 3 business days. Some online lenders offer same-day or next-day pre-approvals for straightforward applications. The speed depends on how quickly you respond to document requests and the lender’s current volume.
