FORM UC-36 (REV. 09-2026)UCDP MANDATE: 2026-11-02
UADCHECKPre-submission inspection of UAD 3.6 packages

UAD1179

WARNING

Official message text · Appendix H-1: UAD Compliance Rules — URAR, v1.5

Provide at least one data source reference for the appraisal.

Warning — the submission can still come back Successful, but the finding is surfaced to your lender's review team.

What triggers UAD1179

The published rule logic, verbatim:

If at least one DataSourceType is not provided

  • • Bound to MISMO data point DataSourceType at ../VALUATION_ANALYSIS/DATA_SOURCES/DATA_SOURCE/

How to fix it

This requirement applies to the XML data itself — the field is delivered in the submission file but is not printed on the form. Your form software populates it from the report data; correct the underlying entry, regenerate the package, and re-check.

UAD1179 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.
