A pre-approval letter feels like a finish line. In reality, "pre-approval" covers everything from a 30-second online guess to a fully-underwritten green light — and in a competitive offer, that gap can cost you the home.
Pre-qualification vs pre-approval
A pre-qualification is an estimate. You tell a lender your income and debts, they do quick math, and out comes a number — nothing verified. A real pre-approval means a lender has collected and reviewed your actual documents and, ideally, run the file through underwriting. When that letter says approved, it's because someone checked.
Why it shows up at the worst time
A weak letter holds up fine until there's competition. The moment you're against other offers, listing agents read letters closely — and a fully-underwritten pre-approval tells the seller this deal will actually close. That confidence can win you the home even against a higher offer. The worse failure: a thin pre-approval that falls apart after you're under contract.
Ask one question: "Has my income and credit been reviewed by an underwriter, or is this based on what I told you?" The answer tells you everything.
How I do it
- I review your real documents up front, not just your word
- For self-employed files, we sort the income picture before you shop
- When I hand you a letter, it's built to hold up under scrutiny
