Which action is prohibited regarding signage on a property?

The correct answer highlights the importance of having an established agency relationship before engaging in certain real estate practices, such as displaying "for sale" signs. In West Virginia, before a property can be publicly advertised or signaled as for sale, there needs to be an agreement between the property owner and the agent or agency representing them. This protects the interests of both the seller and the agent, ensuring that all marketing efforts are authorized and compliant.

Displaying "for sale" signs without an agency relationship misrepresents the intent of the seller and can lead to confusion in the market. It could imply that the property is actively listed with an agent when it is not, which could result in legal complications regarding misrepresentation or unauthorized advertising.

Having the owner's approval for advertising, adding a sign with a licensed agent's name, and installing signs during open houses are all actions that fall within proper practices when there is a valid agency relationship established. These reflect the collaborative nature of real estate transactions and ensure that all parties involved are working legally and ethically.
