How to fix UAD1418
UAD1418 is a UAD 3.6 Warning edit; it may not block delivery, but it is still worth resolving before review.
- 01Open the Sales Comparison Approach › Dwelling(s) › Year Built (%PV%) area of the URAR and find Year Built.
- 02Check the condition that triggers UAD1418: @ValuationUseType = "SalesComparable" and PropertyStructureBuiltYear < 1800 in a given instance of IMPROVEMENT_DETAIL with ImprovementType = "Dwelling".
- 03Review and correct the value when appropriate; this is a Warning, but it can still raise reviewer questions.
- 04Use the official Single-family (SF1) sample value on this page as a reference pattern, then re-run validation.
