Underwriting Invariants & Algebraic Inversions

Machine Precision
Governing Underwriting Formulas:
Monthly Qualifying Income = Deposits · (1 - Expense%) / N_months
Max Purchasing Power = [ (Qualifying Income · Max DTI) - Debts ] / [ (1 - Down%) · m₁ + EscrowFactor ]

Step-by-Step Purchasing Power Derivation

1
Gross Qualifying Revenue

Total Deposits $360,000 with a standard 50% business expense ratio yields $180,000 net qualifying revenue over 12 months = $15,000 monthly qualifying income.

2
Allowable Housing Debt Service (Back-End Inversion)

At 50% Non-QM back-end DTI, total debt capacity is $7,500/mo. Subtracting $800 in personal liabilities leaves $6,700/mo maximum allowable housing PITIA.

3
Purchasing Power Capitalization

At 7.50% APR across 360 months with 20% down, the total monthly housing cost per dollar of purchase price is 0.006932. Capitalizing $6,700 / 0.006932 backsolves to a maximum purchasing power of $966,547.

Frequently Asked Questions: Bank Statement Loans

How does an underwriter calculate income on a bank statement loan? +
Underwriters review 12 or 24 consecutive months of bank statements. They tally all gross qualifying deposits, subtract non-business transfers or unusual cash spikes, and apply an expense ratio (50% standard default or a custom percentage with a CPA attestation letter). For personal checking accounts, 100% of deposits can be credited if supported by separate business account existence.
What credit score is needed for a bank statement mortgage? +
Most wholesale Non-QM bank statement lenders require a minimum credit score between 620 and 660. Borrowers with credit scores of 700+ can access loan-to-values (LTVs) up to 85%–90% with lower reserve requirements.
