An assured tenancy is a legal category of residential tenancy to an individual (or individuals jointly) in English land law. Statute affords a tenant under an assured tenancy a degree of security of tenure.

n. the real estate which is the subject of a lease (a written rental agreement for an extended period of time). The term is commonly used to describe improvements on real property when the improvements are built on land owned by one party which is leased for a long term (such as 99 years) to the owner of the building. For example, the Pacific Land Company owns a lot and leases it for 99 years to the Highrise Development Corporation, which builds a 20-story apartment building and sells each apartment to individual owners as condominiums. At the end of the 99 years the building has to be moved (impossible), torn down, sold to Pacific (which need not pay much since the building is old and Highrise has no choice), or a new lease negotiated. Obviously, toward the end of the 99 years the individual condominiums will go down in value, partly from fear of lessened resale potential. This is generally theoretical (except to lending companies because the security does not include the land) since there are few buildings with less than 50 or 60 years to go on the leases or their expected lifetimes, although there are some commercial buildings which are within 20 years of termination of such leases. In most cases the buildings are obsolete by the end of the leasehold. See also: condominium lease

n. the right to occupy real property permanently, for a time which may terminate upon a certain event, for a specific term, for a series of periods until cancelled (such as month-to-month), or at will (which may be terminated at any time). Some tenancy is for occupancy only as in a landlord-tenant situation, or a tenancy may also be based on ownership of title to the property.
