Leasehold: Method of owning property (usually a flat) for a fixed term but not the land on which it stands. Possession of the property will be subject to the payment of an annual ground rent.

A freehold estate in land (as opposed to a leasehold) is where the owner of the land has no time limit to his period of ownership.
