US CRE Prepay Model Validation

I need an experienced quantitative risk professional to perform an independent validation of our Commercial Real Estate (CRE) Prepayment model that supports the U.S. loan portfolio used in both CCAR and CECL submissions. The model is already built; what I require now is a thorough challenger review that satisfies bank governance standards and withstands scrutiny from the Federal Reserve and internal audit.

Your recent, hands-on experience should center on validating—not building—CRE prepayment or similar behavioral models for large U.S. banks. You will be expected to:

• Re-create and benchmark key model components, including segmentation logic, prepayment curve construction, and performance back-testing.
• Assess conceptual soundness, data lineage, variable selection, and statistical assumptions.
• Replicate performance metrics and stress the model under CCAR supervisory scenarios as well as lifetime loss projections for CECL.
• Produce a concise validation report with clear findings, remediation recommendations, and an executive summary suitable for risk committee review.
• Draft any ancillary documentation needed for inclusion in our CCAR / CECL packages (methodology memo, model change log, and validation tracking forms).

I will provide full model code ( SAS), historical loan-level data, prior submission documents, and our internal model governance template. Please highlight similar bank engagements, the regulatory feedback you have addressed, and your average turnaround time.

If you can start quickly and deliver an audit-ready validation package, I’m ready to move forward.
