Which of the following services does NOT typically involve a real estate sale?

Property management is primarily focused on the ongoing management and operation of a property rather than the sale of real estate. This includes services such as maintaining the property, handling tenant relations, collecting rent, and managing repairs and maintenance. While property management may involve leasing units to tenants, this is not the same as facilitating a sale of property.

In contrast, auctioning, appraising, and leasing often relate directly to the transaction or sale of real estate. Auctioning involves selling properties to the highest bidder, appraising involves determining a property's market value which is essential for sales, and leasing directly relates to renting properties for a period, often leading towards future sales. Thus, property management stands out as the service that does not typically involve a real estate sale.
