Leasehold is a form of land tenure or property tenure where one party buys the right to occupy land or a building for a given length of time. As lease is a legal estate, leasehold estate can be bought and sold on the open market. A leasehold thus differs from a freehold or fee simple where the ownership of a property is purchased outright and thereafter held for an indeterminate length of time, and also differs from a tenancy where a property is let (rented) on a periodic basis such as weekly or monthly.
