After returning from the
Western Front he attended
Fordham University and became a marine manager and joined Peerless Petrochemicals (formerly Peerless Oil Company), the
petroleum transport business founded by his parents, eventually becoming a partner and a harbor pilot. He also owned various real estate parcels ranging from the Matatuck terminal for petroleum products in
Suffolk County and his family's summer home on
Long Beach. The home, which is also known as the
Woolworth Estate, was designed in 1916 by architect
C. P. H. Gilbert for
Frank Winfield Woolworth, reportedly at a cost of $9 million. Parts of the 25,668 square-foot mansion were heavily damaged by fire in January 2015. In 1974, the Careys paid $270,000 to purchase
Seaview Terrace, the fifth-largest mansion in Newport built by
Howard Greenley for
Edson Bradley. They leased the
Châteauesque main house, gatehouse and former stables to
Salve Regina University, which renamed it the Carey Mansion. On August 31, 2009, Salve Regina University terminated the lease with the Carey family and the Careys' daughter began residing in the mansion. The
Syfy network featured the mansion in the first season, second episode of its paranormal reality show
Stranded on March 6, 2013. In 1975, when his elder brother Edward was asked during an interview about Martin's interests, he replied offhandedly, "Oh, he's in real estate and maritime transportation and he was making money renting out his house in Newport to make pornographic movies until the newspapers found out and it was stopped." He renamed the house to Cashelmara and used it as showcase for interior decorators. Later, the residence became vacant and fell into disrepair. The Society for the Preservation of Long Island Antiquities placed it on their list of endangered historic properties in 2010. ==Personal life==
