A “general” mailing to all homes in an Area:

Answer:- A “general” mailing to all homes in an area is unethical if there is a “for sale” sign on the lawn. If there is a “for sale” sign on the lawn, it suggests that the property is actively being marketed. In this case, a “general” mailing to the homeowner may be considered redundant and potentially unethical. It could be seen as an unnecessary intrusion or an attempt to undermine the existing marketing efforts.
