Kathy wishes to sell her property in Nebraska, but the broker purchases it himself without informing her of a recent zoning change. Is this legal?

In this scenario, the broker's failure to disclose the recent zoning change constitutes a breach of fiduciary duty. Brokers have a legal obligation to act in the best interest of their clients, which includes providing full disclosure of any material facts that could affect the value or desirability of the property. A zoning change can significantly impact property value, usage, and potential buyers' interests.

Since the broker purchased the property without informing Kathy about the zoning change, he has not fulfilled his responsibility to provide critical information that could influence her decision to sell, therefore making the transaction unethical and likely illegal under Nebraska's real estate laws. This requirement for disclosure ensures that sellers like Kathy can make informed decisions regarding their property.
