An estate agent is a live or business that arranges the selling, renting, or management of properties and other buildings. An agent that specialises in renting is often called a letting or management agent. Estate agents are mainly engaged in the marketing of property available for sale, and a solicitor or licensed conveyancer is used to prepare the legal documents. In Scotland, however, many solicitors also act as estate agents, a practice that is rare in England and Wales.

"Estate agent" remains the current title for the person responsible for the management of one group of privately owned, all or mostly tenanted properties under one ownership. Alternative titles are factor, steward, or bailiff, depending on the era, region, and extent of the property concerned.
