Real estate is property consisting of land and the buildings on it, along with its natural resources such as growing crops, minerals or water, and wild animals; immovable property of this nature; an interest vested in this (also) an item of real property, buildings or housing in general. In terms of law, real relates to land property and is different from personal property while estate means the "interest" a person has in that land property.

In English common law, real property, real estate, immovable property or, solely in the US and Canada, realty, refers to parcels of land and any associated structures which are the property of a person. In order for a structure to be considered part of the real property, it must be integrated with or affixed to the land. This includes crops, buildings, machinery, wells, dams, ponds, mines, canals, and roads. The term is historic, arising from the now-discontinued form of action, which distinguished between real property disputes and personal property disputes. Personal property, or personalty, was, and continues to be, all property that is not real property.
