or immovable property is a legal term (in some jurisdictions) that encompasses land along with anything permanently affixed to the land, such as buildings. Real estate (immovable property) is often considered synonymous with real property (also sometimes called realty), in contrast with personal property (also sometimes called chattel or personalty). However, for technical purposes, some people prefer to distinguish real estate, referring to the land and fixtures themselves, from real property, referring to ownership rights over real estate. The terms real estate and real property are used primarily in common law, while civil law jurisdictions refer instead to immovable property.
In recent years, many economists have recognized that the lack of effective real estate laws can be a significant barrier to investment in many developing countries. In most societies, rich or poor, a significant fraction of the total wealth is in the form of land and buildings. In most advanced economies, the main source of capital used by individuals and small companies to purchase and improve land and buildings is mortgages -- bank loans for which the real property itself constitutes collateral. Banks are willing to make such loans at favorable rates in large part because if the borrower does not make payments the lender can foreclose, that is, file a court action that lets them take the property and sell it to get their money back. But in many developing countries there is no effective means by which a lender could foreclose, so the mortgage loan industry as such either does not exist at all or is only available to members of privileged social classes.
In law, the word real means relating to a thing (from Latin res, matter or thing), as distinguished from a person. Thus the law broadly distinguishes between real property
(land and anything affixed to it) and personal property (everything else, e.g., clothing
). The conceptual difference was between immovable property, which would transfer title along with the land, and movable property, which a person would retain title to. (The word is not derived from the notion of land having historically been "royal" property. The word royal — and its Spanish cognate real — come from the unrelated Latin word rex, meaning king.)
