When Jamie Madrox originally opened XXX Investigations, he only occupied the top floor of 5 story brownstone in Mutant Town right across the street from a mutant bar called The Power Plant, and just few blocks from Mutant Square subway station.
After Madrox won a million dollars on a game show, he bought the entire building and renovated portions of it to act not only as offices for X-Factor Investigations, but also serve as housing for X-Factor Investigations staff (which may not have been exactly within the building code).
After Mutant Town was destroyed by Arcade, X-Factor Investigations relocated to Detroit, Michigan. In Detroit, Madrox purchased a Victorian manor to serve as offices and living quarters for his staff. When Madrox moved back to New York City, he left the manor and Detroit to Terry Cassidy. Shortly after Madrox's departure, Terry abandoned the manor and spent some time at Cassidy Keep in Ireland before rejoining the team.
Back to New York City
When X-Factor Investigations relocated back to New York City from Detroit, Madrox manged to buy an abandoned funeral home and convert it into the new X-Factor Investigations HQ. The purchase of the building included a hearse.
