How to Complete an Accurate 1003

Borrower Information

All borrower personal information should be entered exactly as it appears on official documentation. This includes:

Full legal names
Social Security numbers
Dates of birth
Current and prior addresses
Marital status (when applicable)

Even small discrepancies can create underwriting delays or require re-disclosures later in the process.

Employment & Income

Income should be entered accurately and supported by proper documentation. This means more than simply listing an employer or income figure.

Best Practices

Full employment history with no unexplained gaps
Correct employer names
Accurate start dates
Income entered exactly as documented (not estimated)

Required Verification Documents

Paystubs
W-2s or tax returns
Verifications of Employment (VOEs)
Supporting documentation for variable, commission, or self-employed income

Entering income that cannot be supported by documentation may result in additional conditions, underwriting revisions, or loan restructuring later in the process.

Assets

Assets should reflect actual, available funds and must be supported by documentation.

Key Details to Include

Correct account types (checking, savings, retirement, investment)
Accurate balances based on statements
Proper sourcing of large deposits
Clear identification of funds needed to close

Supporting Documentation

Bank statements
Retirement account statements
Gift letters and proof of transfer (if applicable)

Unverified or incorrectly entered assets often lead to last-minute conditions and closing delays.

Liabilities

Most liabilities will automatically populate from the borrower’s credit report. However, an accurate 1003 requires confirming that all obligations are fully disclosed and correctly reflected.

Key Items to Review

Undisclosed liabilities not appearing on credit, such as:
- Klarna, Affirm, Afterpay, or other “buy now, pay later” accounts
- Private repayment arrangements or personal loans
Disputed accounts on the credit report
- Any liabilities in dispute must be addressed, as they can delay or suspend underwriting
Missing or incorrect payment amounts
Liabilities that appear on credit without a listed payment must be updated with accurate information

Even when liabilities auto-populate, borrowers should be asked directly whether they have obligations not reflected on their credit. Identifying these early prevents last-minute debt-to-income issues and underwriting rework.

Property Information, Occupancy & Real Estate Owned

Accurate property and occupancy details are critical, as they directly affect underwriting eligibility and loan structure.

Property & Occupancy Details

Property type entered correctly (single-family, condo, townhouse, multi-unit, etc.)
Purchase price or estimated value accurately reflects the contract or valuation
Occupancy intent aligns with borrower use and documentation

Condominium Requirements

Confirm the property is marked as a condo
Ensure HOA dues are entered accurately, as they impact qualifying ratios

Real Estate Owned (REO)

The REO section must be complete and accurate. All properties in which the borrower has an ownership interest should be listed, including:

Primary residences
Second homes
Investment properties

Required Expense Details for Each REO Property

Mortgage payment
Property taxes
Insurance
HOA dues (if applicable)

Incomplete or inaccurate REO information is a common source of underwriting conditions and debt-to-income miscalculations. Verifying this information upfront helps ensure a smoother approval and closing process.
