The enigma with cell towers is strange indeed. Virtually all cell tower site leases have a termination clause that allows the carrier (lessee) to cancel the lease with as little as 30 days notice for any reason. Banks will not lend on a lease that can be canceled. Can't blame them. A real estate buyer will not pay more for real estate with a cell site for the same reason, possible termination of the cell site lease.
Yet a real estate owner who has a cell site on his or her property that is for sale will be very reluctant to sell off the cell site separately because they fear that site sale value would hurt their chances of selling the property.
