UADCHECKPre-submission inspection of UAD 3.6 packages

UAD1051

WARNING

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

The property can only be considered as new construction when 'Year Built' for the dwelling(s) is within 1 year of the 'Effective Date of Appraisal'.

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

What triggers UAD1051

The published rule logic, verbatim:

If NewConstructionIndicator = "true", and PropertyStructureBuiltYear is not the same year, or within 1 year of the AppraisalReportEffectiveDate, for one or more instances of IMPROVEMENT_DETAIL with ImprovementType = "Dwelling".

  • Checked for the Subject property.
  • Allowed range: Extract Year from AppraisalReportEffectiveDate to Extract Year from AppraisalReportEffectiveDate - 1 year.
  • • Bound to MISMO data point NewConstructionIndicator at ../VALUATION_ANALYSIS/PROPERTIES/PROPERTY/PROPERTY_DETAIL/

How to fix it

On the URAR, this lives at: Subject Property → New Construction. Complete or correct that field in your form software, regenerate the package, and re-check before submission.

The free UADCheck inspection evaluates UAD1051 automatically — attach your package and see in seconds whether it fires.
