The Tunt Mansion is where Cheryl Tunt lives in a high class neighborhood of New York City. It is right next door to the Roosevelt Mansion. It is characterized by a lot of ornate moldings, large spacious rooms and ultra-high ceilings. It has been passed down through the Tunt family, inherited from Cornelius Tunt, Cheryl's great-grandfather.
It is unknown whether or not Cheryl has to share the living space with her brother Cecil Tunt.
It has only made one appearance in "El Secuestro."
It appears the Tunt mansion is the new place of operation since ISIS HQ has closed down.
