Which of the following indicates the least permanent interest in a property?

A leasehold estate is indeed indicative of the least permanent interest in a property. This type of estate grants the tenant the right to use and occupy the property for a specific duration, as dictated by the terms of the lease agreement. Once the lease term expires, the tenant must vacate the property, at which point the ownership and control revert entirely to the landlord or property owner.

In contrast, a fee simple absolute represents the highest form of ownership with the most complete set of rights, allowing the owner to use the property indefinitely and transfer it as they wish. Joint tenancy implies shared ownership between two or more parties that can continue until the death of one owner, at which point the property automatically passes to the remaining owners. A life estate provides rights to use and benefit from the property for the duration of a person's life, after which ownership typically reverts to another designated party. Each of these estates reflects a more permanent interest compared to a leasehold estate, reinforcing the idea that a leasehold estate signifies the least permanence in property interest.
