Documents Needed for Mortgage Pre-Approval: Homebuyer Checklist

Getting pre-approved for a mortgage is one of the most important steps in the homebuying process. A mortgage pre-approval shows sellers you’re a serious buyer and helps you understand what you can afford before you start touring homes.

To issue a pre-approval, lenders review specific financial documents that verify your income, assets, debts, and credit history. Knowing what paperwork to gather ahead of time can help you move faster and avoid delays—whether you’re buying a house in Austin, TX or searching for homes in San Diego, CA.

This Redfin article breaks down exactly which documents you need for mortgage pre-approval, why lenders ask for them, and how to prepare so your application stays on track.

Why lenders require documents for pre-approval

A mortgage pre-approval isn’t just an estimate—it’s a conditional commitment based on verified financial information. Lenders must confirm that you meet underwriting guidelines and can reasonably repay the loan.

During pre-approval, lenders review documents to:

• Verify income stability and employment
• Confirm available funds for a down payment and closing costs
• Assess existing debt and financial obligations
• Check creditworthiness and recent credit activity

The more complete and accurate your documentation, the stronger your pre-approval will be.

Situations that may require additional mortgage documents

Lenders may request additional documents to explain income patterns, employment changes, or large financial movements.

You may need extra documents if you have:

• Recent job changes
• Gaps in employment
• Bonus, commission, or overtime income
• Gift funds for your down payment
• Recent credit inquiries or new accounts
• Divorce or legal separation

Providing these upfront can prevent delays later.

How long documents stay valid for pre-approval

Most mortgage pre-approvals are valid for 60 to 90 days. Exact timelines cary by lender. After that, lenders usually require updated versions of:

• Pay stubs
• Bank statements
• Credit checks

Even within the approval window, major financial changes—like taking on new debt or changing jobs—can affect your pre-approval.

Tips to prepare documents before applying

To make the process smoother:

• Gather digital copies (PDFs are ideal)
• Avoid large unexplained deposits
• Don’t open new credit accounts
• Respond quickly to lender requests
• Keep documents consistent and up to date

Being organized upfront can significantly speed up your timeline.

2. Can I get pre-approved without tax returns?

Some lenders may issue a limited pre-approval, but full documentation is typically required before making offers.

3. Will lenders verify documents again later?
