The lease for Guantanamo Bay, established in 1903 between the United States and Cuba, does not have a specific expiration date. It grants the U.S. perpetual control over the area as long as the U.S. maintains the naval base and pays the agreed-upon rent, which Cuba has historically rejected. Thus, as of now, there is no set expiration for the lease.
Ground rent is a complicated real estate concept that is almost never used in the US. The advantages of a ground rent lease are that a perpetual income is derived from a property, the disadvantages of the ground rent is that it can make a property very difficult to sell.
