Real estate is both a term and an industry. The formal definition of the words “real estate” is “property consisting of land or buildings.” The term also refers to the entire industry that deals with the buying and selling of properties. There are several types of professionals who work in real estate. Real estate agents broker homes for buyers and sellers. Landlords buy houses or buildings and rent them to tenants — they might also buy commercial property and rent retail or office space to business owners. There are also subcategories of the real estate industry. Appraisers evaluate properties for buyers, sellers, and banks. Building managers handle rental units and maintain buildings for owners.
