source ↗Research gaps: Pass 2 retracts the WSJ 2022 listing entries, which were cited via Wikipedia and not seen directly, and replaces them with The Real Deal's reporting of the Feb 2025 $45M sale. It also swaps the ProPublica search-page citations for org pages with EINs. A reported ~$33.5M Southampton lot added to a family compound (Aug 2026) was seen only in low-tier outlets and is left out. The family office name, Koch, Inc. litigation, and the Giants closing date and price are still unverified.
