What Is Preapproval?
Mortgage preapproval is a lender's conditional commitment to lend a specific amount based on verified income, assets, employment, and a hard credit check. Unlike prequalification, preapproval involves a formal application and document review — producing a letter that carries significant weight with sellers. Preapproval letters are typically valid for 60 to 90 days. The commitment is conditional on the property appraisal, title review, and no material changes to the borrower's financial situation before closing.
Key Facts
- Preapproval requires a formal mortgage application (Uniform Residential Loan Application, Form 1003), pay stubs, W-2s, tax returns, bank statements, and a hard credit pull
- A preapproval letter is valid for 60 to 90 days in most cases — after expiration, the borrower must re-apply and provide updated documentation
- In competitive markets, a preapproval letter is essentially required to make a credible offer — listing agents routinely reject offers without preapproval as a condition of consideration
- The hard credit inquiry from preapproval typically reduces the credit score by 5-10 points, but multiple mortgage inquiries within a 14-45 day window (depending on scoring model) count as a single inquiry
- Preapproval is NOT a final approval — the loan can still be denied during full underwriting if the property appraises low, title issues surface, or the borrower's financial situation changes
How Does Preapproval Work?
The preapproval process is a substantive evaluation of the borrower's ability to obtain a mortgage:
- Formal application: The borrower completes the Uniform Residential Loan Application (Form 1003), providing detailed information about income, employment, assets, debts, and housing history.
- Document submission: The borrower provides supporting documentation — typically 2 recent pay stubs, 2 years of W-2s, 2 years of tax returns, 2 months of bank statements, and identification.
- Credit check: The lender pulls a tri-merge credit report (all three bureaus) and reviews the full credit history — not just the score, but payment patterns, outstanding debts, collections, and derogatory marks.
- Automated underwriting: Many lenders run the application through Desktop Underwriter (DU) or Loan Product Advisor (LPA) to get a preliminary approve/refer recommendation.
- Preapproval letter: If the borrower meets guidelines, the lender issues a letter specifying the approved loan amount, program (conventional, FHA, VA), and any conditions.
What Does a Preapproval Letter Include?
A strong preapproval letter typically states:
- The maximum loan amount the borrower is approved for
- The loan program (conventional, FHA, VA, USDA)
- The interest rate range (or current rate lock information)
- The down payment amount
- The letter's expiration date
- Conditions (subject to property appraisal, title review, no material financial changes)
Some listing agents prefer specific preapproval letters that state the offered price rather than the maximum approved amount — revealing your full budget can weaken negotiating position.
Preapproval vs. Prequalification
- Prequalification: Self-reported data, no documents, no hard credit pull, informal estimate. Good for initial planning. Weak with sellers.
- Preapproval: Verified data, full documentation, hard credit pull, conditional commitment. Required for competitive offers. Strong with sellers.
In practice, the distinction is critical. A prequalified buyer is expressing interest; a preapproved buyer is demonstrating capacity. Sellers in competitive markets will choose a preapproved offer over a prequalified one, all else being equal.
What Can Go Wrong After Preapproval?
Preapproval is conditional. Common reasons a preapproved loan gets denied during full underwriting:
- Job change or loss: Employment is re-verified before closing. Changing jobs, reducing hours, or switching from salary to commission can jeopardize the loan.
- New debt: Opening a credit card, financing furniture, or co-signing a loan changes the DTI ratio and can push the borrower out of guidelines.
- Large deposits or withdrawals: Unexplained large deposits or gift funds without proper documentation trigger underwriting conditions.
- Low appraisal: If the property appraises below the purchase price, the lender may not approve the full loan amount.
- Credit score drop: Late payments, collections, or increased utilization during the process can drop the score below program minimums.
The cardinal rule: do not make any significant financial changes between preapproval and closing.
Frequently Asked Questions
How long does preapproval take?
With all documents ready, preapproval can be completed in 1 to 3 business days. Some online lenders offer same-day preapproval. The timeline depends on how quickly you provide documentation and whether any issues need resolution (credit disputes, income verification for self-employment, etc.).
Does preapproval guarantee I'll get the loan?
No. Preapproval is conditional — the property must appraise, title must be clear, and your financial situation must not change materially. Full underwriting occurs after you make an offer and select a property. Preapproval means the lender has verified your finances and is prepared to lend, but final approval depends on the property and unchanged conditions.
Should I get preapproved with multiple lenders?
Yes — comparing preapproval offers helps you find the best rate and terms. Multiple mortgage credit inquiries within a 14-45 day window count as a single inquiry for scoring purposes, so shopping doesn't significantly impact your credit. Compare rates, fees, and total loan costs.
What documents do I need for preapproval?
Standard documents include: 2 recent pay stubs, W-2s for the last 2 years, federal tax returns for the last 2 years, 2 months of bank statements, government-issued ID, and Social Security number. Self-employed borrowers also need a profit-and-loss statement and business tax returns.
Can I be preapproved with an FHA loan?
Yes. FHA preapproval follows the same general process but uses FHA-specific guidelines — minimum 580 credit score for 3.5% down (500-579 requires 10% down), DTI up to 57% with compensating factors, and FHA-specific property requirements. The preapproval letter will specify it's for an FHA loan.
