Residences can be classified by 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 Residential real estate may contain either a single family

multifamily structure that is available for occupation or for non-business purposes. Luxury real estate is sometimes used as a way to store value, especially by wealthy foreigners, without any particular attempt to rent it out.
