What type of estate grants a temporary right to possession without transferring title?

The correct answer is "Leasehold" because a leasehold estate specifically refers to a temporary right to occupy and use a property without transferring ownership of the title to that property. In a leasehold arrangement, the tenant (lessee) has the right to use the property for a specified period as determined by the lease agreement. This arrangement maintains the landlord's (lessor's) ultimate ownership and title, while allowing the tenant to enjoy possession and benefits associated with the property during the lease term.

In contrast, other estate types listed, such as a Qualified Fee, Fee Simple Determinable, and Fee Simple on Condition Subsequent, are forms of ownership that involve a transfer of title or an estate that can, under certain conditions, revert to the original owner if certain criteria are not met or specific events occur. Thus, they do not grant merely possession but rather encompass broader rights associated with ownership.
