These two terms get used interchangeably — but they're very different. One means almost nothing. The other actually gets you into a home.
Pre-qualification
A pre-qualification is a quick, informal estimate of what you might be able to borrow. The lender takes your self-reported income, assets, and debts at face value — no documents required, no credit pull. It takes 10 minutes and the result is a rough ballpark number. Most sellers and real estate agents know a pre-qualification letter doesn't carry much weight.
Pre-approval
A pre-approval is a real underwriting review. The lender pulls your credit, verifies your income and employment with actual documents (W-2s, pay stubs, tax returns), and reviews your assets. At the end you get a pre-approval letter with a specific loan amount. This tells sellers you're a serious buyer who has already been vetted.
What you'll need for pre-approval
- Last 2 years of W-2s or tax returns (self-employed: 2 years of returns + P&L)
- Last 30 days of pay stubs
- Last 2-3 months of bank statements
- Government-issued ID
- Social Security number (for credit pull)
- Information on any debts or other real estate owned
How long does a pre-approval last?
Typically 60-90 days. After that, the lender may need to refresh your credit and verify income again. If you're not under contract within that window, expect to re-submit some documents.
Pre-approval requirements vary by lender. A pre-approval is not a guarantee of final loan approval — full underwriting happens after you're under contract.
