Mortgage Pre-Approval: The Complete Guide

What pre-approval actually means, what you need for it, and why it matters before you start touring homes. A clear, jargon-free breakdown from Yellow.

What pre-approval actually is

Pre-approval is a lender's conditional commitment to loan you a specific amount, based on a real look at your income, assets, debt, and credit. It's more substantial than a pre-qualification (more on that difference in our pre-approval vs. pre-qualification guide) and it's usually the first concrete step in the homebuying process that involves a lender actually verifying your information rather than just taking your word for it.

A pre-approval typically comes with a letter — a short document sellers and agents will ask to see before taking an offer seriously.

Why it matters before you start touring homes

  • It sets a realistic budget. You're shopping with real numbers, not guesses.
  • Sellers take you seriously. In any competitive market, an offer without a pre-approval letter attached is easy to pass over.
  • It surfaces problems early. If something in your credit or income needs attention, you want to know that months before closing, not days before.

What you'll typically need

  • Proof of income (pay stubs, W-2s, tax returns, or business records if self-employed)
  • Bank statements showing assets for down payment and reserves
  • Authorization for the lender to check your credit
  • Basic personal and employment information

Exactly what's required varies by lender and loan type, which is part of why having someone coordinate the process — rather than juggling several lenders' different document requests — saves real time.

How long it takes and how long it lasts

Pre-approval typically takes anywhere from same-day to a few business days, depending on the lender and how quickly documentation comes together. Most pre-approval letters are valid for 60–90 days, after which they usually need to be refreshed.

Pre-approval isn't a guarantee

It's conditional — the lender still needs to underwrite the specific property (appraisal, title, final verification of your financial picture) before the loan is fully approved and funded. Big financial changes between pre-approval and closing — a new car loan, a job change, a large credit card purchase — can affect what a lender is willing to finalize.

Where Yellow fits in

Yellow coordinates the pre-approval process alongside everything else in the homebuying journey — insurance, inspections, title, and beyond — so buyers have one place to track progress instead of separate emails and portals for every party involved. Start your pre-approval.
