The Greenwich Time reports that town records show the Colonial home in Greenwich was placed on the market for $3.8 million in July and sold for $3 million in September.
The buyer, Raymond LaChance, told the newspaper that the fact that Philbin is the former owner is "kind of neat," but that did not influence his and his wife's decision to purchase the house.
The home has nearly 6,000 square feet of space and sits on six acres near a state park. It also includes a pool, a tennis court and a gazebo.
The Philbins own another home less than two miles away and an apartment in Manhattan.
