What is the title of an agent who sells property at auction?

The term specifically used for an individual who conducts the sale of property at auction is "auctioneer." An auctioneer is trained and licensed to manage the auction process, which includes announcing the items for sale, facilitating bidding, and closing the sale once the highest bid is achieved. This role is critical as the auctioneer must ensure the auction runs smoothly and that all legal requirements are followed during the process.

In contrast, a broker typically deals with the buying and selling of property, usually in a real estate context, rather than specifically conducting auctions. An appraiser's role involves assessing the value of a property rather than selling it, which distinguishes them from auctioneers. While the term "agent" can refer to someone who represents a buyer or seller in transactions, it is not specific to the auction context. Therefore, "auctioneer" is the most accurate title for someone specifically selling property at auction.
