Final answer:
The buyer wanting to keep prices low, while affecting the broker's commission, doesn't create a conflict of interest since it doesn't pit the broker's personal interests against their professional duties. Hence, this scenario is not a conflict of interest.
Step-by-step explanation:
A conflict of interest in a business context occurs when an individual's personal interests could influence their professional decisions in a way that is contrary to the interests of their clients or the organization they work for. Evaluating the options given:
- The broker representing her sister could lead to biased decisions in favor of her sister, hence it's a conflict of interest.
- A buyer's broker sitting on the planning board could be influenced to make decisions that benefit themselves or their clients, which is a conflict of interest.
- The buyer wanting to keep prices low is a clear goal in a transaction, but it isn't necessarily a conflict of interest since lower prices don't inherently create a situation where the broker's personal interests conflict with their professional duties.
Therefore, the scenario that would NOT be defined as a conflict of interest is c. The buyer wants to keep prices low, which could result in a lower commission for the buyer's broker, but doesn't create a conflict between the broker's personal and professional interests.
