Simple definition
A pre-approval is a lender's written statement estimating how big a mortgage you qualify for, after they've checked your income, debts, and credit. Think of it as a permission slip you carry while house hunting: it tells you your realistic price range and signals to sellers that you're a serious, ready buyer. It's stronger than a quick pre-qualification because the lender has actually verified your numbers.
Why it matters
A pre-approval keeps you shopping in a price range you can actually finance and stops you from falling for a home you'll be denied. In competitive markets, sellers often won't even consider an offer without one, so it can be the difference between winning and losing a house.
Real-life example
Before touring homes, you send a lender your pay stubs, tax returns, and bank statements. They review your finances and issue a letter saying you're pre-approved for up to $280,000. Now you focus on homes at or below that price, and you can attach the letter to an offer to show sellers you're ready.
Common mistakes
- Confusing a quick pre-qualification with a fully verified pre-approval — sellers value the latter.
- Shopping at the very top of your pre-approval amount instead of a payment you can afford.
- Opening new credit or making big purchases before closing, which can sink your approval.
- Letting the pre-approval expire, since most last only a couple of months.
Pro tips
- Get pre-approved before you tour homes so you shop in a real price range.
- Compare offers from a few lenders — rates and terms vary more than people expect.
- Keep your finances steady between pre-approval and closing; avoid new debt.
- Ask what the letter covers and when it expires so you can time your search.

Frequently asked questions
What's the difference between pre-qualification and pre-approval?
Pre-qualification is a rough estimate based on numbers you tell the lender, with little verification. Pre-approval goes further: the lender checks your credit and reviews documents like pay stubs and tax returns, then issues a written commitment estimate. Because it's verified, a pre-approval carries far more weight with sellers when you make an offer.
Does getting pre-approved hurt my credit?
It usually involves a hard inquiry, which can nudge your score down a few points temporarily. If you're comparing several lenders, do it within a short window — scoring models typically treat multiple mortgage inquiries in that period as one. The small, brief dip is generally worth knowing your real buying power.
How long does a pre-approval last?
Most pre-approval letters are valid for a limited window, often around two to three months, because your finances and rates can change. If yours expires before you find a home, the lender can usually refresh it with updated documents. Ask your lender for the exact expiration date so you can plan your search around it.
Knowing what Pre-Approval means is knowledge — the first half. A brick gets placed when you act on it: gather your recent pay stubs, tax returns, and bank statements so you're ready to apply for pre-approval.
