Real estate is a legal term (in some jurisdictions, notably in the USA) that
encompasses land along with anything permanently affixed to the land,
such as buildings, specifically property that is stationary, or fixed in
location. Real estate is often considered synonymous with real
property (also sometimes called realty), in contrast with personal
property (also sometimes called chattel or personalty). However, in some
situations the term "real estate" refers to the land and fixtures
together, as distinguished from "real property," referring to ownership
rights of the land itself.
The terms real estate and real property are used primarily in common
law, while civil law jurisdictions refer instead to immovable property.
