Which of the following actions could result in legal issues for a broker?

Discussing commission rates with another broker can lead to potential legal issues due to antitrust laws. These laws are in place to prevent price-fixing and promote fair competition. When brokers collaborate or communicate about commission rates, it can create a perception of a cartel-like agreement, which is illegal. The real estate industry is governed by these laws to ensure that pricing remains competitive and fair; thus, any actions that could suggest collusion among brokers regarding commission structures can attract scrutiny from regulatory bodies.

In contrast, failing to advertise listings online does not directly result in legal issues, although it might affect business performance. Conducting open houses is a standard practice in real estate and typically does not pose legal risks when done in accordance with local laws and regulations. Providing property appraisals is usually performed by licensed appraisers and, while it should be done accurately, it does not inherently involve legal issues for a broker unless there is a significant misrepresentation or negligence.
