What term refers to the act of negotiating on behalf of only the landlord?

The act of negotiating on behalf of only the landlord is referred to as the landlord's agent. This term specifically designates the fiduciary relationship where the agent's loyalty and legal responsibilities lie solely with the landlord. As a landlord's agent, the individual or entity represents the interests of the landlord in real estate transactions, which includes negotiating leases, ensuring tenant compliance, and handling the financial aspects of property management.

In a legal context, this relationship is established through a listing agreement or a similar contractual arrangement, reflecting the duty to act in the landlord's best interests. The landlord's agent must prioritize the landlord's needs in all dealings, ensuring that the terms of agreements favor the landlord and comply with relevant laws and regulations governing landlord-tenant relationships.

The other terms presented do not apply in this situation: a tenant's agent represents the tenant's interests; a transaction-broker facilitates a transaction without representing either party; and a customer refers to someone receiving services but not under a fiduciary relationship. This distinction is critical in understanding the roles within real estate agreements.
