How to Get Pre-Approved for a Mortgage

There's a version of pre-approval that's essentially a polite guess, and a version that's backed by real underwriting. One wins competitive offers. One doesn't. Here's the difference and how to get the right one.

Pre-Qual A rough estimate based on a conversation. No credit pull, no verification, no real weight with sellers.
Pre-Approval Credit pulled, documents reviewed. A real conditional commitment. What most buyers carry into offers.
DU Approval Run through Fannie Mae's Desktop Underwriter. An underwriting decision before you're even under contract. The strongest letter you can hand a seller.

Pre-Qual, Pre-Approval, and DU Approval: They're Not the Same

Most buyers come into this process thinking pre-approval is pre-approval. It's not. There are three distinct levels, and the one you have determines how seriously sellers take your offer.

Level 1
Pre-Qualification
Based on a conversation. You tell the lender your income, assets, and debts. They give you a number. No documents, no credit pull. It takes 10 minutes and means almost nothing to a seller who has competing offers on the table.
Avoid in competitive markets.
Level 2
Standard Pre-Approval
Credit is pulled, income and assets are reviewed. The lender issues a letter stating they're conditionally willing to lend you a specific amount. Most buyers have this. It's solid, but still based on the loan officer's manual review, not a formal underwriting decision.
Good. Acceptable in most markets.
Level 3
DU-Backed Approval
Your file runs through Fannie Mae's Desktop Underwriter before you're under contract. DU is the same system underwriters use to approve loans. A DU approval means you've already passed automated underwriting. Sellers and listing agents recognize this letter immediately.
The strongest pre-approval you can get.

What Lenders Check During Pre-Approval

When you apply for pre-approval, lenders look at four things: your credit, your income, your assets, and your debt load. Each one affects how much you can borrow and at what rate.

Credit Score

Most loan programs have a minimum score. FHA loans require at least 580 for 3.5% down. Conventional loans typically require 620 or higher. VA loans don't have a hard minimum, but most lenders want to see 580 to 620. A higher score means better rate options. If your score is borderline, a loan officer can usually tell you what to pay down or fix before you apply.

Income and Employment

Lenders verify you have steady, documented income. W-2 employees are the easiest to verify: two years of W-2s, a month of pay stubs, and you're done. Self-employed borrowers need two years of tax returns and business documentation. The key number lenders calculate is your debt-to-income ratio (DTI): your total monthly debt payments divided by your gross monthly income. Most programs want DTI below 43 to 45%.

Assets and Down Payment

Lenders want to see that your down payment and closing costs are coming from verified funds. Two to three months of bank statements typically. If you're receiving a gift, you'll need a gift letter. Large unexplained deposits will require a paper trail. The cleaner your bank statements, the faster this piece moves.

Documents to Gather Before You Apply

Having these ready before you apply is one of the single biggest things you can do to speed up the process. Lenders can't move forward without them, and every day spent chasing a document is a day added to your timeline.

Government-issued photo ID
Social Security number
Pay stubs from the last 30 days
W-2 forms for the past two years
Federal tax returns (2 years)
Bank statements (2-3 months, all pages)
Investment or retirement account statements
Employer contact information
Rental history or landlord contact (if applicable)
Gift letter (if receiving down payment help)

Self-employed borrowers also need two years of business tax returns, a year-to-date profit and loss statement, and business bank statements.

4 Factors That Determine Your Approval

Credit Score and History
Your score affects which loan programs you qualify for and what interest rate you receive. Payment history carries the most weight. Late payments in the last 12 months are a significant flag. Collections and judgments need to be addressed. One or two small derogatory marks usually don't kill a file, but a pattern of late payments does.
Debt-to-Income Ratio
DTI is the ratio of your monthly debt obligations to your gross monthly income. Add up all your monthly minimum payments (car, student loans, credit cards, any other installment debt) plus your projected mortgage payment, then divide by your gross monthly income. Most programs want that number under 43 to 45%. FHA sometimes allows up to 57% with compensating factors.
Employment and Income Stability
Lenders want to see at least two years of employment history in the same field. A job change within the same industry is usually fine. A gap in employment, a career switch, or switching from W-2 to self-employment recently requires more documentation and explanation. Stability matters more than salary level.
Assets and Down Payment Source
The size of your down payment affects your loan-to-value ratio, whether you'll pay mortgage insurance, and which programs you qualify for. More importantly, lenders need to verify where those funds are coming from. Seasoned funds (sitting in your account for 60+ days) are easiest. Recent large deposits, cash, or gifts require additional documentation.

What Happens After Pre-Approval

Pre-approval isn't the end. It's the starting line. Once you're pre-approved, you're cleared to start shopping. Your letter will specify a maximum loan amount and typically has an expiration date of 60 to 90 days.

When you make an offer and it's accepted, your lender moves into the full application and underwriting phase. The strength of your pre-approval determines how smooth that transition is. A DU-backed file usually sails through final underwriting because the automated decision was already made. A basic pre-qual borrower often faces more conditions, more documentation requests, and more delays.

Keep your financial situation stable between pre-approval and closing. Don't open new credit accounts. Don't make large purchases. Don't change jobs. Lenders verify your financial profile again before funding. Anything that changed since the pre-approval will need to be re-evaluated.
