Real estate, 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.
