Mortgage pre-approval: the complete guide

The ticket that turns "I'm looking" into "I can close" — what it is, what to gather, and how to use it.

Pre-qualification vs pre-approval — not the same thing

Pre-qualification is a conversation and an estimate. Pre-approval means a lender has actually checked your credit, income, and assets and committed — subject to the property and final underwriting — to lend a specific amount. Sellers' agents treat the two completely differently, and in a competing-offer situation a strong pre-approval letter is table stakes.

What to gather before you apply

• Two years of W-2s (or tax returns if self-employed) and recent pay stubs
• Two months of statements for every account feeding the down payment
• Photo ID and Social Security number for the credit check
• Documentation of any large deposits — underwriters will ask where they came from

Expect a hard credit inquiry; its effect on your score is small and short-lived. What matters more: don't open new credit or move money around oddly between pre-approval and closing — lenders re-verify both.

How much will you be approved for — and how much should you take?

Lenders size your loan off debt-to-income ratios (36% is the classic comfort zone, 43% is a common ceiling) plus credit score and down payment. The approved maximum is not the smart target: budget for the payment you'd still be happy paying if rates, insurance, or life change. Our affordability calculator shows that number honestly.

Using it well

• Match the letter to the offer — a letter for exactly the offer price doesn't reveal your ceiling to the other side.
• Keep it current — most letters last 60–90 days; renew rather than let one go stale mid-search.
• Shop lenders inside a rate-shopping window — multiple mortgage inquiries within roughly 14–45 days count as one for scoring purposes.
• Stay predictable — no new cars, furniture financing, or job changes until the keys are yours.

A pre-approval doesn't commit you to a house or a lender. It commits the lender to you — which is exactly why it moves your offers to the front.
