The disgraced former prince has now been stripped of his style, title and honours, and is being removed from the 30-room Royal Lodge.
A copy of the leasehold agreement, shared with the PA news agency by the Crown Estate, which oversees the royal family's land and property holdings, shows Andrew signed a 75-year lease on the property in 2003.
It reveals he paid £1 million for the lease and that since then he has paid "one peppercorn" of rent "if demanded" per year.
