Which of the following is NOT a type of real estate?

Furniture is not considered a type of real estate because real estate refers specifically to land and any structures, property, or rights associated with it. Real estate encompasses various categories, such as residential property, which includes homes and apartments; investment property, which is real estate purchased to generate income; and agricultural property, which pertains to land used for farming or growing crops. These categories all involve the ownership and management of land or buildings, while furniture is classified as personal property, which consists of movable items not fixed to land or buildings. Thus, identifying furniture as the option that does not belong to the real estate category is accurate.
