Real estate is "property consisting of land and the buildings on it, along with its natural resources such as crops, minerals or water; immovable property of this nature; an interest vested in this (also) an item of real property, (more generally) buildings or housing in general. Also: the business of real estate; the profession of buying, selling, or renting land, buildings, or housing." It is a legal term used in jurisdictions whose legal system is derived from English common law, such as India, the United Kingdom, United States, Canada, Pakistan, Australia, and New Zealand.
Residential real estate may contain either a single family or multifamily structure that is available for occupation or for non-business purposes.
Residences can be classified by if and how they are connected to neighbouring residences and land. Different types of housing tenure can be used for the same physical type. For example, connected residences might be owned by a single entity and leased out, or owned separately with an agreement covering the relationship between units and common areas and concerns.
The size of an apartment or house can be described in square feet or meters. In the United States, this includes the area of "living space", excluding the garage and other non-living spaces. The "square meters" figure of a house in Europe may report the total area of the walls enclosing the home, thus including any attached garage and non-living spaces, which makes it important to inquire what kind of surface area definition has been used. It can be described more roughly by the number of rooms. A studio apartment has a single bedroom with no living room (possibly a separate kitchen). A one-bedroom apartment has a living or dining room separate from the bedroom. Two bedroom, three bedroom, and larger units are common. (A bedroom is a separate room intended for sleeping. It commonly contains a bed and, in newer dwelling units, a built-in closet for clothes storage.)
