No county-record distress flags across 1 researched property on the ARED base layer. Key-figure check: median price diverges 85.2% from the nearest retained anchor (researched-property base layer) — beyond the 12.5% tolerance; an automated validation case is open and the value publishes pending its verdict. Validation: the flagged $239,900 could not be independently corroborated and was removed pending review (no prior-cycle value to revert to); the case is under review in the Command Center.
