Answer:
Transaction broker for buyer and agent for seller
Explanation:
A transaction broker is a third-party in a real estate deal that offers his/her services to buyers and sellers. A transaction broker is neutral by law and is different from a real estate agent but is bound by the same laws as the real estate agent.
Since a transaction broker can provide services to both buyer and seller, there is no need for an agent for the seller as it is a bad combination. Asides from the fact that both parties would be paid separately for their services which is not very cost effective. Moreso, an agent will be paid a percentage of the sale value but a transaction broker will be paid a flat fee.
I hope this helps.
