Which of the following is NOT considered real property?

Trade fixtures are items that are attached to a property for business purposes, and while they are considered improvements to the real estate, they are classified as personal property rather than real property. This classification means that when a tenant vacates a property at the end of their lease, they are usually allowed to remove trade fixtures they installed.

In contrast, trees, buildings, and water rights are classified as real property. Trees and buildings are inherently part of the land and are considered immovable, while water rights pertain to the legal rights to use water from a specific source, which is also tied to real estate ownership. Therefore, trade fixtures qualify as personal property, distinguishing them from the other options that constitute real property.
