Which of the following refers to the property manager's responsibility to show properties?

The correct answer is leasing, as this term specifically encompasses the property manager's role in showing properties to prospective tenants. Leasing involves not just the act of finding tenants but also presenting the property, highlighting its features, and addressing questions during showings. This phase is crucial for securing tenants who are suitable for the property, and it ultimately affects occupancy rates and the overall success of the property management process.

Marketing, while related, primarily focuses on promoting the property through various channels to attract potential renters. It encompasses broader strategies that may include advertising, creating listings, and developing outreach programs. Client relations involve maintaining good communication and managing relationships with property owners and tenants but does not explicitly pertain to the act of showing properties. Property maintenance refers to the upkeep and repair of the physical property and is separate from the responsibilities associated with leasing activities.
