Which of the following will NOT be considered relevant if HUD investigates a prospective home buyer's allegation of discriminatory treatment by a licensee in a brokerage office?

This information is highly relevant as it can provide evidence of whether the licensee displayed bias in the types of properties presented to the prospective buyer. A pattern of showing only certain properties based on discriminatory factors would be scrutinized during an investigation.

The presence of the HUD Equal Housing Opportunity poster is also relevant, as it indicates the licensee's commitment to fair housing practices. Its absence can be interpreted as a lack of adherence to HUD regulations, potentially supporting allegations of discrimination.

Undercover testers are used to gather objective evidence regarding discriminatory practices. Their reports can provide critical insights into how the licensee interacts with different prospective buyers, making this information very pertinent to the investigation.
