FATALEligibility

Official message text · Freddie Mac Collateral Feedback Messages for UAD 3.6 (2026-08-04)

The appraisal report indicates that the Lack of Heating System is not Typical for the Market. Please refer to the Freddie Mac Seller Guide for property eligibility requirements.

Fatal — this finding makes the submission NOT SUCCESSFUL until resolved.

What triggers FRE76124

FRE76124 is a Freddie Mac proprietary finding (Eligibility). It is returned by Loan Collateral Advisor®/UCDP® after your lender submits — this layer is explicitly outside the GSE UAD Compliance API, so your form software's built-in check does not run it. The first time most appraisers see it is in a revision request.

  • Checked for the Subject property.
  • • Bound to MISMO data point LackOfHeatingSystemTypicalToMarketIndicator

How to fix it

On the URAR, this lives at: Dwelling Exterior → Mechanical System Details. Complete or correct that field in your form software, regenerate the package, and re-check before submission.

FRE76124 is in UADCheck's reference library; automated coverage for it is on the roadmap. The inspection already runs the full GSE schema, the package-integrity layer, and every auto-checkable compliance rule — each report states exactly what was covered.
