Submitting a complete and accurate mortgage application is the most critical step toward homeownership. According to recent industry data, 31% of mortgage buyers experienced at least one denial before final approval in 2024. The primary reason for delays or denials is often incomplete documentation. This comprehensive checklist details the essential documents you need to gather, which lenders use to verify your identity, assess your financial stability, and determine your risk profile, ultimately improving your chances of a smooth approval process.
Lenders must verify your identity to comply with federal regulations like the U.S. Patriot Act. You will need to provide a government-issued photo ID, such as a driver’s license or passport. If you don't have these, lenders may accept two alternative IDs, like a green card or military ID. Crucially, you must also provide your Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN), which the lender uses to pull your credit history and ensure compliance with federal laws.
Lenders need a clear picture of your earning history and stability. Typically, this requires your pay stubs from the last two months and W-2 forms from the past two years. For a more in-depth look, they will also request your complete tax returns from the last two years. If you have additional income streams—such as spousal support, rental income, or side gig earnings—you must provide documentation like court decrees or lease agreements.
The specific documents vary by employment type:
Your bank statements serve as a tangible record that the income listed on your pay stubs is being deposited. Lenders usually request two to three months of statements from your checking and savings accounts. They are looking for consistency and verifying that you have sufficient funds for the down payment, closing costs, and sometimes cash reserves. Unexplained large deposits can raise questions, so be prepared to document any significant gifts or transfers.
Lenders also consider your assets, which can strengthen your application. You may need to provide statements for:
To determine if you can afford a new mortgage payment, lenders calculate your debt-to-income (DTI) ratio. This ratio compares your monthly debt obligations to your gross monthly income. You may need to provide records for auto loans, student loans, credit card balances, and other recurring debts. This helps the lender confirm your DTI, a key factor in loan approval.
Your history of making housing payments on time is a significant factor. If you rent, you’ll need to provide a year’s worth of canceled rent checks or bank transfers, and potentially a letter from your landlord confirming timely payments. This is especially important for applicants with a limited credit history. If you own a home, be prepared to show records of your mortgage, insurance, and property tax payments.
Several unique situations require additional paperwork:
