10 Bank Statement Analysis Tips Every Mortgage Broker Should Know
Speed up your loan processing with these expert bank statement analysis tips used by top mortgage brokers to quickly verify income, spot red flags, and close more loans.
1. Review All 3 Months Before Looking at Any Details
Before diving into individual transactions, scan all three months of statements for the big picture. What's the balance trend? Is it growing, stable, or declining? This 30-second overview will frame everything else you see and help you decide how deeply to scrutinize individual transactions.
2. Separate Business Transfers from Income
One of the most common mistakes in bank statement analysis is counting transfers between a borrower's own accounts as income. A business owner who moves $5,000 from their business account to their personal account every month might look like they have $5,000 in monthly income — but if that transfer appears as both a deposit (personal) and a withdrawal (business), it's just money moving, not income earned.
3. Always Calculate the NSF Rate, Not Just the Count
Five NSF events sounds alarming. But 5 NSFs over 36 months is very different from 5 NSFs in the most recent month. Calculate NSFs as a rate: events per month, and look at the trend. Improving trends with zero recent NSFs may be acceptable for otherwise strong files.
4. Look for the Payroll Pattern First
For W-2 borrowers, find the payroll deposits immediately — they should be the most regular, predictable deposits in the account. If payroll deposits don't appear consistently, investigate. Some borrowers cash their checks rather than deposit them, which can hide their true income.
5. Flag Every Round-Dollar Daily ACH Debit
Scroll through the transactions and flag any ACH debits that occur daily or weekly in round amounts. These are almost always MCA loan repayments. Calculate the monthly cost: a $150/day MCA debit costs $3,300/month in a 22-business-day month.
6. Check the Average Daily Balance, Not Just the Ending Balance
The ending balance shown on a bank statement can be misleading. A borrower might have a $10,000 ending balance but routinely dip to $200 mid-month. Average daily balance provides a more accurate picture of the account's typical health.
7. Identify Rent/Mortgage Payment Timing
Find when the borrower's current housing payment clears. If their rent/mortgage clears on the 1st but they consistently have near-zero balances on the 29th-31st, their cash flow is extremely tight. This matters for payment-ability analysis even if income looks adequate.
8. Note Large Unexplained Deposits
Any deposit that doesn't fit the regular income pattern needs explanation. Common legitimate explanations include tax refunds, insurance settlements, asset sales, and gifts. Unexplained large deposits in the months just before application could be borrowed funds — which would affect the debt-to-income ratio.
9. Compare Month-to-Month, Not Just to the Average
Averages can hide important patterns. A borrower with $8,000, $14,000, and $8,000 in monthly deposits has a $10,000 average — but the pattern matters. Was the high month unusual? Is income declining back to $8,000? Understanding the story behind the numbers is crucial.
