We commonly are approached by tenants who are working with multiple brokers or who have previously seen properties with other brokers. Due to NC Licensing Law your NC broker cannot “poach” a client nor work with someone who has signed an exclusive agreement with another broker.
On a practical note, tenants who use multiple brokers tend to have much less success in finding space as the brokerage community can perceive them to be aligned with others.
A good broker is loyal to their client and will go out of their way to find a space for their client before thinking of non-clients.
