Honestly it’s looking more and more like the Archer TV series was a white hat military op.

“ What if Kushner bought 666 Fifth Ave to make [them] think he was in their club? Did you know that Vanderbilt had an 18th century estate in that exact spot? Satanic indoor pool? Ritual tunnels? What's under it?
Payseur Vanderbilt > Railroads/Shipping > Traffickers?”

Tunt Manor, Tuntmore House or Tunt Mansion is the ancestral home and primary residence of Cheryl Tunt. Located on the Northwest corner of 5th Avenue and 55th Street New York City, the Gilded Age mansion is said to be right next door to the Roosevelt Mansion. It is characterized by its polished marble walls and floors, 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 (Cornelius Tunt).
The home is first seen in the episode El Secuestro. To prove her story of about Pam Poovey’s kidnapping, Cheryl Tunt takes Sterling Archer, Lana Kane, and Malory Archer to the estate and shows them a family portrait of her, her brother Cecil Tunt and their parents Mr. and Mrs. Tunt to prove that she is really a member of the Tunt family.
It appears that Cheryl does not have to share the living space with her brother Cecil Tunt as he's never seen on the premises.
Season Six picks up with the spy supplies being moved out of Tunt Manor and back into the office. The estate makes a formal appearance in the episode, Pocket Listing in which Slater orchestrates an overly elaborate ruse to gain information of the Duhranian Royal family using Tunt Manor as the setting. Cheryl acts as a real estate agent and expounds upon the mansion's history while the agents pose as the house's domestic staff.
