Key-figure check: median price diverges 21.8% from the nearest retained anchor (published ten-year series (2025)) — beyond the 12.5% tolerance; an automated validation case is open and the value publishes pending its verdict. Research outlier held out — this pass returned a median of $609,000 (21.8% off the retained reading), contradicting every independent anchor; the prior reading stands pending corroboration. Validation: confirmed genuine market swing — the flagged $609,000 was independently re-read and corroborated by 2 source(s); it stands as the new anchor baseline.
