How This Record Was Verified
- Method
- Compiled from published press reports and the property records in this archive, not from any submission by the agent. A deal appears only where press names Deborah Kern on the transaction. Deborah Kern cannot amend this page except by producing evidence a stated fact is wrong.
- Open entries
- Corcoran’s $80.25 million 2023 Deal of the Year at 220 Central Park South appears under Awards; the unit has not been matched to a press-reported closing, so it is not shown as a deal card. Penthouse 26 at One High Line is shown as reported in contract until a recorded closing is published. A $52 million 2023 sale at 150 Charles Street is attributed to Kern by a data aggregator but contradicted by The Real Deal and is excluded.
