Quick takeaways
- Pre-qualification is generally an informal, quick estimate based on self-reported information.
- Pre-approval generally involves a lender verifying documentation and often includes a credit check, resulting in a conditional written estimate of how much you might borrow.
- Neither is a final loan commitment — final approval typically happens later, after underwriting a specific property.
Pre-qualification vs. pre-approval, generally speaking
| Pre-qualification | Pre-approval | |
|---|---|---|
| Basis | Usually self-reported income, debt, and assets | Usually verified through documents and often a credit check |
| Typical output | An informal, rough estimate | A conditional written estimate, sometimes called a pre-approval letter |
| Typical speed | Often minutes | Often a few days, depending on documentation |
| General weight in an offer | Generally limited | Often viewed as more credible by sellers and agents |
Practices vary by lender; some lenders use these terms differently. Always ask a specific lender what their process actually verifies.
Documents typically requested for pre-approval
- Recent pay stubs, or two years of tax returns for self-employed or variable income
- Recent bank and investment account statements
- Two years of W-2s or 1099s, where applicable
- Identification and Social Security number, for a credit check
- Information on any other debts, such as auto loans or student loans
- Documentation for gift funds, if any are being used toward a down payment
What a pre-approval letter generally represents
A pre-approval letter is typically a written, conditional estimate of how much a lender might be willing to lend, based on the documentation reviewed at that point in time. It is generally not a guarantee: final loan approval usually still requires underwriting a specific property, which can include an appraisal and title review, and conditions can change if a borrower's financial situation changes before closing.
Why timing matters
Pre-approval letters are typically valid for a limited window (often around 60–90 days, though this varies by lender), because income, debt, and credit can change. Large purchases or new credit accounts between pre-approval and closing can sometimes affect final approval.
Common general steps in the process
- Gather income, asset, and debt documentation
- Submit an application with a lender (often more than one, for comparison)
- Lender reviews documents and typically runs a credit check
- Lender issues a conditional pre-approval letter, if the review supports it
- Letter is used when making offers, subject to full underwriting later
