A widow who owns a condominium unit holds which type of estate?

The correct choice is that the widow holds a freehold estate. A freehold estate is characterized by ownership of real property for an undefined duration. In this case, since the widow owns a condominium unit, she possesses full ownership rights, which include the ability to occupy, use, transfer, and enjoy the property without a predetermined end date. This ownership is in contrast to leasehold estates, which involve a tenant occupying property for a specific period under a lease agreement.

A life estate would involve ownership that lasts for the lifetime of the owner or a designated person, after which the property would revert to another party or pass to a remainderman. Since the question specifies that the widow owns the condominium outright and not for her lifetime, this doesn’t apply. Tenancy in common refers to a shared ownership situation among multiple parties, where each co-owner holds an individual interest in the property. In this scenario, as the question outlines a single owner, this concept is also not applicable.

Thus, the widow’s condition of owning a condominium unit aligns best with the definition of a freehold estate.
