Summary
Film producer Eric Eisner, son of late Disney CEO Michael Eisner, purchased a 6,800-square-foot Upper East Side townhouse for just under $10 million, acquiring the property at a significant markdown following years of family litigation. The residence at 178 East 73rd Street features six bedrooms, four bathrooms, an elevator, chef's kitchen, library, gym, and garden terrace, and was originally purchased by hedge fund manager Jason Ader for $13 million in 2010.
The sale resolved a contentious family dispute centered on Ader's default of a $13 million Bank of America loan secured by the property. According to public records, Richard Ader, the property's original guarantor and founder of U.S. Realty Advisors, required his son to sign a 2020 agreement stipulating repayment obligations with interest. The accord granted Richard—and subsequently his estate—the right to sell the property upon default. After Richard Ader's death, his widow Pamela Ader, acting as estate executor, filed suit against Jason Ader and his entity JS Property Holdings LLC in 2024 on breach of contract grounds following the 2023 loan default.
Jason Ader contested the 2020 agreement's enforceability through his legal counsel, asserting in court filings that he executed the document "under extreme pressure." Despite this objection, a New York judge ordered the forced sale, enabling Pamela Ader to proceed as executor. Eisner signed the purchase contract in March 2026, roughly three months after the property's market listing at $10.9 million. Adam Modlin of the Modlin Group represented both parties in the transaction but declined to comment on deal specifics.
The sale price of just under $10 million reflects a 23% loss from Ader's 2010 acquisition cost, illustrating the financial deterioration resulting from both the bankruptcy and protracted legal proceedings. The transaction closes a chapter on what court documents and family correspondence characterize as a bitter intergenerational property dispute with significant personal and financial stakes for all parties involved.
