Before you fall in love with a home, it pays to know exactly what you can borrow — and to prove it to sellers. That's what a mortgage pre-approval does. Here's how it works and why it's one of the smartest first moves a buyer can make.
Pre-qualification vs. pre-approval
These terms get used interchangeably, but they're not the same thing.
- Pre-qualification is an informal estimate. You share basic numbers about your income, debts, and assets, and the lender gives you a ballpark of what you might borrow. Your information generally isn't verified, so it's a quick starting point — not a guarantee.
- Pre-approval is a more formal, documented review. The lender checks your credit, verifies your income and assets, and issues a pre-approval letter stating how much you're approved to borrow. It carries far more weight with sellers.
For a serious home search, aim for a pre-approval.
Why it matters before you shop
Getting pre-approved first does several important things:
- Sets a realistic budget so you tour homes you can actually buy
- Strengthens your offers — sellers take pre-approved buyers seriously, which matters in a competitive market
- Speeds up your closing because much of the legwork is already done
- Surfaces issues early, giving you time to fix credit or paperwork problems before they cost you a home
Making an offer with a pre-approval letter in hand is a real advantage — see how to make a competitive offer on a home.
Documents you'll typically need
Every lender is a little different, but be ready to provide:
- Proof of income — recent pay stubs, and often W-2s
- Tax returns — usually the last two years
- Bank and asset statements — to show funds for the down payment and reserves
- Identification and your Social Security number (for a credit check)
- Employment details — lenders like to see stable income
Self-employed? Expect a bit more documentation, such as profit-and-loss statements. Gathering these early makes the process smooth.
What lenders look at
A few key factors shape your approval and terms:
- Credit — your history and score influence the rates you're offered
- Income and employment — steady, verifiable income is key
- Debt-to-income ratio (DTI) — this compares your monthly debt payments to your monthly income. As a general concept, lenders prefer to see this ratio on the lower side, and there are common thresholds many lenders use. Paying down debt before applying can help.
- Assets and reserves — cash left after your down payment reassures lenders
This is general education, not financial advice. A licensed lender can explain how these factors and current rates apply to you.
A few tips to prepare
- Check your credit ahead of time and dispute any errors
- Avoid new debt — don't open credit cards or finance a car mid-process
- Don't move large sums around without documenting where they came from
- Keep your job situation stable until after closing
- Ask about the details — rate, loan type, and estimated monthly payment including taxes and insurance
In South Florida, ask your lender to factor in wind/hurricane insurance and any HOA fees, since those affect the monthly payment lenders and you should plan around.
Pre-approval isn't final approval
A pre-approval is a strong signal, but the loan still goes through full underwriting once you're under contract, and an appraisal must support the price. Keep your finances steady until you have the keys.

Get pointed to the right lender
A good agent works hand-in-hand with trusted local lenders and can help you line up pre-approval before you tour a single home. Eduardo Gil and the Delivers Realty team help South Florida buyers get prepared, get pre-approved, and shop with real confidence.
