What must the Board do upon receiving a written complaint?

Upon receiving a written complaint, the Board is required to conduct an investigation regardless of the validity of the complaint. This procedural obligation ensures that every complaint is taken seriously and that due diligence is exercised in reviewing the claims made. It reflects the Board's responsibility to uphold standards within the real estate profession and to protect the public interest.

Investigating all complaints allows the Board to determine whether there is merit to the complaint, which can lead to disciplinary actions if needed, or to dismiss the complaint if it is found to be unfounded. This process not only helps in maintaining professional integrity but also assures the public that their concerns are being adequately addressed.

The other options do not align with the Board's duty to ensure accountability and transparency. Dismissing a complaint without action would neglect potential issues that require attention, notifying the licensee immediately could compromise the investigative process, and performing a background check on the complainant is not typically part of the initial procedure when a complaint is received.
