What does Real mean as in Real Estate?

Answer 1

The word 'Real' in real estate stems from the Spanish word meaning Royal as in 'Real Madrid' and pertains to the historic era in which immovable property was only owned by Royalty. Over the centuries property has become available for purchase by anyone but retains the former root word as identification.

Answer 2

The term real estate is first recorded in England in the 1600s. In this sense real was/is used in law to distinguish immovable property (land and buildings) from personal property.

Real is found as early as the 4th century in Old French reel- real or actual, and in Late Latin realis, actual.
