Final answer:
An agent should meet a prospective buyer at the agent's office, as it offers a professional environment to discuss buyer needs, handle paperwork, and utilize available resources.
Step-by-step explanation:
When an agent is preparing to meet with a prospective buyer prior to showing any properties, it is considered best practice to meet at the agent's office. This setting is professional and allows the agent to establish a formal relationship with the buyer, discuss the buyer's needs in a private and comfortable environment, take care of any necessary paperwork, and discuss details such as safety, privacy, and agency disclosures. Additionally, the office provides access to property listings, other resources, and sometimes the support of other agents or staff members.
