GREENWOOD LAKE — “I’ve been telling everybody I live right next-door to Derek Jeter. I’m a big Yankee fan,” said a man who lives near the six-bedroom, lakefront mansion the former all-star shortstop owns at 14 Lake Shore Road. “Actually, I live two doors down."That neighbor wouldn’t give his name.The mansion, which Jeter bought in 2004, is up for sale at $14.75 million.
