Conservative talk show host Sean Hannity closed Wednesday on a house in Centre Island, a real estate source tells Newsday. He paid $8.5 million for the 6.2-acre property, the source says. He bought the 16-room home from a trust named “2002 JLD Childrens,” which was set up after a transfer of the property from Deborah Dolan, ex-wife of Cablevision chief executive James L. Dolan. The house had been listed for $13.5 million. Read more about the property here.
