How to Get Preapproved for a Mortgage

Nobody sits you down before your first home search and explains that "preapproved" and "prequalified" mean two very different things — and that showing up to an open house with the wrong one can cost you the house. I found that out the hard way, the same way most people do: by getting it wrong once first. So here's the version I wish someone had given me upfront.

Preapproval vs. Prequalification — The Difference That Actually Matters

Prequalification is a quick, self-reported estimate with no document verification. Preapproval is a real underwriting review — credit pull, verified income and assets — that produces a conditional loan commitment letter sellers actually trust.

A prequalification is a quick, informal estimate based on numbers you self-report — no documents, no credit pull in most cases, just a conversation or an online form. It takes minutes and tells you roughly what you might qualify for.

A preapproval is a real underwriting review. The lender pulls your credit, verifies your income and assets with actual documents, and issues a conditional commitment letter stating a specific amount they're willing to lend you. Sellers and real estate agents know the difference — in any competitive market, an offer backed by prequalification alone gets taken far less seriously than one backed by real preapproval.

What Preapproval Actually Checks

• Credit score and history — a hard credit pull, which is why timing this matters (more on that below)
• Income verification — pay stubs, W-2s, or tax returns if you're self-employed
• Asset verification — bank statements showing your down payment and closing cost funds are real and sourced properly
• Debt-to-income ratio — your existing monthly debts weighed against your income
• Employment verification — confirming you're actually employed where your documents say you are

Documents to Gather Before You Apply

Document	Why It's Needed
Last 2 pay stubs	Verifies current income
Last 2 years W-2s or tax returns	Verifies income history and stability
Last 2-3 months bank statements	Verifies down payment and closing funds
Photo ID	Identity verification
List of debts (loans, cards, etc.)	Calculates your debt-to-income ratio

How Long Preapproval Actually Takes

With documents ready, most lenders issue a preapproval letter in 1-3 business days. The letter is typically valid for 60-90 days, so time your application around when you'll actually start house hunting.

With documents ready in hand, most lenders can issue a preapproval letter within 1-3 business days. Missing documents or self-employment income (which requires deeper verification) can stretch this to a week or more. Preapproval letters are typically valid for 60-90 days — worth timing your application around when you actually plan to start seriously house hunting, not months in advance.

Common Mistakes That Slow This Down or Hurt You

• Applying with multiple lenders spread out over weeks. Multiple mortgage-specific credit inquiries within a focused 14-45 day window (the exact window varies by credit scoring model) are typically counted as a single inquiry for scoring purposes — but spreading applications out over months can genuinely ding your score multiple times.
• Making a large purchase or opening new credit between preapproval and closing. Lenders often re-check credit right before closing. A new car loan or furniture financed on a store card can change your debt-to-income ratio enough to jeopardize final approval.
• Depositing large, unexplained cash sums before applying. Underwriters flag unusual deposits and will ask for a paper trail — gift funds need a formal gift letter, and cash sitting outside a bank for a while can complicate verification.
• Not accounting for self-employment income complexity. If you're self-employed, lenders typically average your last two years of tax returns — a recent income jump won't fully count yet, which surprises a lot of business owners.

What Happens After You're Preapproved

You'll receive a preapproval letter stating the maximum loan amount and the rate assumptions it's based on. This is what you attach to offers when house hunting. Note that preapproval is not final approval — once you're under contract, the lender still orders an appraisal, does final underwriting, and can adjust or deny based on the specific property or any changes in your financial picture between preapproval and closing.

Frequently Asked Questions

Does getting preapproved hurt my credit score?

It causes a small, typically temporary dip from the hard credit inquiry — usually a few points. Multiple mortgage preapproval inquiries within a short window are generally treated as one inquiry by credit scoring models, so shopping several lenders in a tight timeframe doesn't multiply the impact.

Can I get preapproved before I've found a house?

Yes — and it's actually the recommended order. Getting preapproved first tells you your real budget before you start touring homes, which prevents falling for something outside your actual range.

Is preapproval the same as being guaranteed a loan?

No. It's a strong conditional commitment based on the information verified at that time, but final approval still depends on the specific property (via appraisal) and confirming nothing material has changed in your financial situation before closing.

What credit score do I need to get preapproved?

This varies by loan type — conventional loans typically want 620+, FHA loans can go as low as 580 with 3.5% down (or 500 with 10% down). Preapproval is worth pursuing even with a lower score; the letter will simply reflect what you qualify for at your current profile.

Can my preapproval amount change after I apply for houses?

Yes — if your income, debt, or credit changes materially between preapproval and your offer, or if you're applying for a specific loan program with different requirements, the number can shift. It's meant as a strong estimate, not an unchangeable guarantee.

Should I get preapproved with more than one lender?

Getting 2-3 preapprovals within a short window lets you compare rates and fees directly, and gives you real leverage to negotiate — the same strategy that works for closing costs works here too.

What if I get denied for preapproval?

Ask the lender specifically why — common reasons include debt-to-income ratio too high, insufficient credit history, or income documentation gaps. Each of those is addressable: paying down debt, waiting to build credit history, or gathering better documentation before reapplying.
