Which automated software feature informs the agent when a property has been listed that matches the needs of his or her client?

The correct choice, which is related to the automated software feature that notifies an agent about new property listings that align with their client's requirements, is property matching. This feature uses algorithms to compare the characteristics of newly listed properties against the preferences and needs specified by the client. When a suitable match is found, the system automatically alerts the agent, facilitating timely communication and potential transactions.

The other options represent functionalities that may be useful in real estate, but they serve different purposes. A client alert typically refers to notifications sent to clients about specific market changes or updates rather than matching properties to their requirements. Listing notification may hint at a broader range of alerts about listings, but it does not specifically indicate the personalized matching process. Market analysis usually involves evaluating property prices and trends rather than directly notifying agents about specific property matches for individual clients. Thus, property matching is the most precise term for the functionality described.
