Non-QM Underwriting Deep Dive
The right question is rarely “Does Non-QM allow this?” It is “Which investor's method fits this borrower and transaction?”
Build the file from the actual strength
Identify what makes the borrower strong: recurring deposits, 1099 earnings, business cash flow, liquid assets, rental cash flow, equity, reserves, recovered credit, or some combination. Then match that strength to a program designed to measure it.
Deep-dive topics
Investor matrix, not a universal Non-QM rule. Bank-statement calculations, expense factors, DSCR formulas, asset haircuts, credit-event seasoning, LTV, reserves and documentation can vary materially by investor and lender. MortgageDadOf3 separates the concept from the actual program matrix so a lender overlay is not mistaken for an industry-wide rule.
Consumer-purpose loans still require the applicable consumer-protection analysis. For covered transactions, Regulation Z’s Ability-to-Repay framework generally requires a reasonable, good-faith determination of repayment ability. Alternative documentation is not the same thing as “no documentation.”
