When a landowner allows one or more persons, called "tenants", to use the land in some way for some fixed period of time, the land becomes a leasehold, and the resident- (or worker-) landowner relation is called a "tenancy". A tenant pays rent (a form of consideration) to the landowner. The leasehold can include buildings and other improvements to the land. The tenant can do one or more of: farm the leasehold, live on it, or practise a trade on it. Typically, leasehold estates are held by tenants for a specific period of time.
