02 What you need to know
The difference between prequalification and preapproval
Prequalification
A prequalification is often based on what you tell the lender: your estimated income, debts and savings. It may or may not include a credit check. It’s a useful starting point, but nothing has been verified.
Preapproval
A preapproval generally involves a credit pull and a review of documents like pay stubs, W-2s or tax returns, and bank statements. Many lenders also run your file through an automated underwriting system (AUS), the software Fannie Mae, Freddie Mac and FHA lenders use to evaluate a loan.
Underwritten approval
A stronger option is having an underwriter review your file before you’ve found a home. This is sometimes called a “TBD” approval, because the property address is “to be determined.” Your credit, income and assets are signed off in advance.
The names aren’t standardized
The CFPB notes that lenders use these terms inconsistently. One lender’s “preapproval” may be another’s “prequalification.” Ask what was actually verified.
03 Real-world example
Prequalified vs. preapproved vs. underwritten: side by side
| Prequalified | Preapproved | Underwritten approval | |
|---|---|---|---|
| Credit pulled | Sometimes | Generally yes | Yes |
| Income documents reviewed | Usually not | Yes | Yes, by an underwriter |
| Assets reviewed | Usually not | Yes | Yes, by an underwriter |
| AUS findings | Rarely | Often | Yes |
| Strength with sellers | Low | Moderate to strong | Strongest |
| Still needs appraisal, title & final checks | Yes | Yes | Yes |
Assumptions: general comparison only. What each step includes varies by lender and loan program.
Say two buyers offer the same price on a home in Los Angeles. One has a prequalification letter based on a phone call. The other has a preapproval backed by reviewed documents and AUS findings. The listing agent calls both lenders. The second buyer is usually the safer bet for the seller.
04 What most people overlook
What a preapproval doesn’t cover
A preapproval is not a final loan commitment. Before closing, your lender still needs:
- An appraisal that supports the price
- A clear title report
- Property approval, including condo project review if you’re buying a condo
- Updated pay stubs and bank statements
- Final verification of employment and credit
Your finances need to stay steady until funding. See why not to open new credit before closing, and know that pre-approvals expire.
A strong preapproval tells a seller what’s been checked. Make sure it’s tailored to your offer price, not your maximum.
05 How I’d approach it
How I’d build a preapproval that holds up
A letter is only as strong as the documents behind it. I want sellers to know I’ve already done the work.
I start by pulling credit and collecting your income and asset documents, then run your file through automated underwriting. For self-employed or complex files, I may request an underwriter review before you shop.
When you write an offer, I issue a letter for that specific price and down payment, so you don’t reveal your maximum to the seller.
And I pick up the phone when the listing agent calls. Explaining what’s been verified often matters as much as the letter itself.
