The narrower term 'tenancy' describes a lease in which the tangible property is land (including at any vertical section such as airspace, storey of building or mine). A premium is an amount paid by the tenant for the lease to be granted or to secure the former tenant's lease, often in order to secure a low rent, in long leases termed a ground rent. For parts of buildings it is most common for users to pay also by collateral contract, or by the same contract, a service charge which is normally an express list of services in a lease to minimize disputes over service charges. A gross lease or tenancy stipulates a rent that is for the global amount due including all service charges.
