Which type of property includes leasehold interests as defined in title 33?

The correct answer is real estate because leasehold interests are classified as interests in real property as defined under Title 33. Real estate encompasses not only the physical land and buildings but also the rights associated with the land, including leasehold interests. A leasehold interest allows a tenant to occupy land or property owned by another party for a specified period under specific conditions, and these rights are considered an integral part of real property law.

In contrast, commercial property refers specifically to real estate that is used for business purposes. Personal property involves movable items that are not attached to land or buildings, and vacant land is simply land that is not currently developed or constructed upon. Thus, while leasehold interests are tied to the use and occupation of real estate, they do not pertain specifically to commercial property, personal property, or vacant land in isolation.
