How to fix UAD1734
UAD1734 is a Fatal UAD 3.6 edit, so clear it before the appraisal report goes to UCDP.
- 01Open the Prior Sale and Transfer History › Comparable Transfer History › Transfer Terms area of the URAR and find Transfer Terms.
- 02Check the condition that triggers UAD1734: @ValuationUseType = "SalesComparable" and PriorSalesOrTransfersIndicator = "true", and (at least one instance of SALES_HISTORY is not provided or OwnershipTransferTransactionType is not provided in a given instance of SALES_HISTORY).
- 03Correct the missing, invalid, duplicate, or inconsistent value before submitting to UCDP.
- 04Use the official Single-family (SF1) sample value on this page as a reference pattern, then re-run validation.
This fix guidance is derived from the published rule message, trigger logic, report location, field definition, and official sample data available for this rule.
