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, furniture, money). 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.)
With the development of private property ownership, real estate has become a major area of business. Purchasing real estate requires a significant investment, and each parcel of land has unique characteristics, so the real estate industry has evolved into several distinct fields. Cities such as Vancouver, British Columbia have experienced remarkable growth in real estate prices in the new millennium. Specialists are often called on to valuate real estate and facilitate transactions.
