For a long time, some people could take the real estate agent for a taxi driver or a tourist guide who drive people from houses to houses, especially on weekends. It must be recognized that it may have been and, perhaps, that it is still the case sometimes, but it is not the role of the real estate agent.
The proof is that today the main part of appointments take place, not at the agency, but directly on site of the visit. Buyers expect the agent to be a real estate professional, able to advise them and to respond to their requests, not to drive them. Meanwhile, the discovery of the neighborhood is part of the accompaniment offered by a real professional.
