Excellent — let’s now focus specifically on the Post-Close Non-QM Underwriter role — which combines traditional post-closing QC review with the manual-credit, non-agency, and investor-specific compliance nuances of Non-Qualified Mortgage (Non-QM) lending.
Below is a full, structured breakdown of what a Post-Close Non-QM Underwriter does, their workflow, tools, and investor QC requirements — all sourced from:
- CFPB Regulation Z (§1026.43 – Ability-to-Repay / QM Rule)
- MBA Quality Control Best Practices (2024)
- Fannie Mae & Freddie Mac Post-Close QC standards (for reference only)

🧭 1. What is a Post-Close Non-QM Underwriter?
A Post-Close Non-QM Underwriter is a specialized quality-control underwriter who audits closed Non-QM loans before sale or securitization to ensure:
- Compliance with Ability-to-Repay (ATR) rules under Regulation Z
- Adherence to investor-specific overlays (e.g., Angel Oak, Deephaven)
- Accuracy of manual income and asset calculations
- Proper documentation for non-traditional income types (bank statements, DSCR, asset depletion, etc.)
- File readiness for loan purchase or securitization in the secondary market
They act as the final quality gatekeeper between funding and investor delivery.
🧩 2. Key Purpose of Post-Close Non-QM Underwriting
| Objective | Description |
|---|---|
| Validate ATR Compliance | Ensure documentation supports borrower’s ability to repay despite non-standard income |
| Investor Eligibility Review | Confirm loan aligns with the specific Non-QM investor’s matrix |
| Defect Detection | Identify miscalculations, missing documentation, or unverified assets |
| Compliance Validation | Confirm TRID, HOEPA, HPML, and state-specific disclosure compliance |
| File Integrity | Ensure all documents match LOS (e.g., Encompass) data and investor delivery dataset |
⚙️ 3. Post-Close Non-QM Workflow (Step-by-Step)
Step 1 – File Selection & Assignment
- QC or Post-Close Department selects loans (100 % audit for Non-QM due to investor risk).
- Pulls closed package: Final CD, ATR Worksheet, Income Analysis, Bank Statements, Appraisal, Notes.
- Assigns to Post-Close Underwriter for compliance and investor delivery prep.
Step 2 – Re-Underwriting for ATR (Ability to Repay)
The underwriter re-verifies that the loan satisfies ATR criteria per 12 CFR § 1026.43(c):
Eight factors reviewed:
- Income or assets used for repayment
- Employment status
- Monthly payment on covered transaction
- Monthly payment on simultaneous loans
- Monthly payment for mortgage-related obligations (taxes, insurance, HOA)
- Current debt obligations, alimony, child support
- Monthly DTI or residual income
- Credit history
If any are weak, the underwriter documents compensating factors in the QC Worksheet.

Step 3 – Program & Documentation Verification
| Non-QM Program | Post-Close Verification |
|---|---|
| Bank Statement Program | Average deposits × expense ratio = qualifying income; verify no transfer circularity or non-business deposits |
| DSCR (Investor Cash Flow) | Confirm DSCR ≥ 1.0; compare rent schedule (1007) vs. PITIA |
| Asset Depletion | Validate net assets, less reserves ÷ term → monthly income; check liquidity of assets |
| 1099 / Contractor | Match YTD 1099 income to bank deposits |
| Foreign National | Confirm visa validity and foreign credit reference letter |
Step 4 – Credit & Collateral Validation
- Re-review credit report & supplements.
- Confirm minimum FICO meets program (typically 600 +).
- Validate mortgage/rental history 12–24 months.
- Review appraisal for accuracy, USPAP compliance, and investor overlay (e.g., second review for $ > $ 1 M loans).
Step 5 – Regulatory & Compliance Review
Post-Close Non-QM Underwriter verifies:
- ATR/QM Worksheet signed and complete
- TRID timing (LE, CD, redisclosure within required days)
- HPML / High-Cost / HOEPA tests passed
- State anti-predatory rules (e.g., NY, CA, MA)
- LO Compensation compliance (Reg Z § 1026.36)
- Anti-fraud verification (CoreLogic FraudGuard or LoanSafe)

Step 6 – Data Integrity & Encompass Validation
- Compare key fields (loan amount, income, LTV, DTI, reserves) in LOS vs. final docs.
- Ensure data points match Investor Delivery File (MISMO 3.4).
- Flag any manual data entry errors for correction before funding sale.

Step 7 – Defect Identification & Categorization
| Severity | Example |
|---|---|
| Critical (Tier 1) | Missing ATR Worksheet, unsupported income calculation, fraud red flag |
| Significant (Tier 2) | TRID timing violation, unverified deposit |
| Minor (Tier 3) | Typo in Encompass or missing non-critical initials |
Defects are logged in QC software (e.g., ACES, QuestSoft).
The Post-Close Underwriter creates a QC report with remediation instructions.
Step 8 – Remediation / Delivery
- Coordinate with Processor or Compliance to cure defects.
- Ensure corrected files uploaded to Investor Portal (Angel Oak, Deephaven, etc.).
- Document “clean QC certification” before loan boarding or pool delivery.
- Archive QC Report for audits (min. 2 years per investor policy).
