A suspected squatter who allegedly took over a $1 million Queens home is now subletting space in the house, one of the illegal sub-squatters told The Post on Wednesday. Kevin Ballasty said he was conned into paying $1,500 a month to live in the basement of the Flushing home, with the deal made with “Jay,” who he identified as the squatter first exposed by WABC-TV. Ballasty said he brokered the deal through a “realtor” he identified as David Dubon.
