Derek Jeter ain't got time to sit on a throne anymore -- dude DOES have a baseball team to run these days -- so now you can ... if you've got NEARLY $15 MILLION LAYING AROUND!!!
The Yankees legend is parting ways with an 11,000-square-foot castle in New York that he used as a summer vacation home when he was a kid.
It used to belong to his grandpa ... but Jeter bought the Greenwood Lake place way back in 2002 -- 'cause, well, it's a dope castle.
Jeets is pretty busy now as a part-owner of the Miami Marlins .
