Which of the following terms describes the rights retained by the landlord after leasing a property?

The term that describes the rights retained by the landlord after leasing a property is "reversion." This concept refers to the landlord's interest in the property that returns to them upon the expiration or termination of the lease. Essentially, when a property is leased, the landlord grants the tenant exclusive use of the property for a specific period, but the ownership rights and the ability to reclaim possession of the property remain with the landlord. Thus, once the lease ends, the landlord has the right to regain full control of the property.

Reversion is significant in understanding property rights and the landlord-tenant relationship, as it ensures that the landlord ultimately retains ownership and can either lease the property again or use it for their purposes once the lease has concluded.

In contrast, the other terms do not accurately capture the rights of landlords post-lease. An assignment involves the tenant transferring their rights to another party, subordination refers to the prioritization of claims or interests against a property, and co-tenancy relates to multiple parties having ownership or rights in the same property. None of these terms indicate the landlord's retained interest like reversion does.
