Bank Statement Underwriting: The Complete Underwriter's Checklist
A comprehensive checklist for underwriters reviewing bank statements. Cover income, cash flow, red flags, MCA loans, and risk assessment in one structured process.
The Underwriter's Bank Statement Review Framework
Consistent, thorough bank statement underwriting requires a structured process. Whether you're reviewing a single statement or processing dozens per week, following the same checklist ensures nothing is missed and decisions are defensible.
Phase 1: Document Verification (5 minutes)
Before analyzing content, verify the documents themselves:
- Confirm the bank name, account number (last 4 digits), and account holder name match the application
- Verify statements are consecutive with no missing months
- Confirm statements are complete — all pages included, no obvious deletions
- Check the statement period dates cover the required review period
- Look for signs of alteration — inconsistent fonts, blurry sections, misaligned text
Phase 2: Income Analysis (10-15 minutes)
- Identify and list all recurring deposits with source, amount, and frequency
- Classify each deposit: payroll, business income, transfer, gift, refund, or other
- Exclude non-income deposits from the qualifying income calculation
- Calculate average monthly qualifying income for each income source
- Note income consistency: is each source consistent, growing, or declining?
- Calculate total average monthly qualifying income
Phase 3: Expense and Obligation Analysis (10 minutes)
- Identify all recurring monthly obligations: rent/mortgage, car payment, insurance, utilities
- List all loan and credit card payments
- Identify any MCA repayments (daily/weekly fixed ACH debits)
- Calculate total monthly obligations from the bank statement
- Compare bank statement obligations to application-disclosed obligations — are they consistent?
Phase 4: Red Flag Assessment (10 minutes)
- Count NSF events by month and calculate trend
- Count overdraft events and calculate total overdraft fees
- Flag any gambling transactions and calculate monthly total
- Identify any large unexplained deposits (>25% of monthly average)
- Note any negative balance days and duration
- Flag any accounts opened or closed during statement period
Phase 5: Cash Flow Analysis (10 minutes)
- Calculate average monthly deposits (gross cash in)
- Calculate average monthly withdrawals (gross cash out)
- Calculate net monthly cash flow (deposits minus withdrawals)
- Calculate DSCR: net cash flow divided by proposed payment
- Assess ending balance trend month over month
- Identify average daily balance
Phase 6: Risk Scoring and Decision (5 minutes)
Based on the above analysis, assign a risk rating:
- Approve: Strong income, consistent cash flow, DSCR >1.4x, no or minimal red flags
- Approve with conditions: Adequate income and cash flow, minor red flags that can be explained
- Refer/Review: Income meets minimum requirements but cash flow is tight, or moderate red flags present
- Decline: Insufficient income, negative cash flow, multiple serious red flags, MCA stacking
