1. Pennsylvania State Real Estate Commission Rules and Regulations, 49 Pa. Code § 35.304. Disclosure of interest. This regulation states: "A licensee may not participate in a real estate transaction involving property in which he has an ownership interest unless he first discloses his interest in writing to all parties." While the rule specifies disclosure to "all parties," its application is interpreted to include advertising to ensure transparency from the outset.
2. Pennsylvania Real Estate Licensing and Registration Act, 63 P.S. § 455.604(a)(18). This section on Prohibited Acts forbids "Making any representation in any... advertisement... that is false, deceptive, or misleading." Advertising a property for sale by owner without disclosing that the owner is a licensee could be deemed misleading by omission, as the public is not aware they are dealing with a professional.
3. Pannabecker, F., & Finkelstein, M. (2022). Modern Real Estate Practice in Pennsylvania (14th ed.). Dearborn Real Estate Education. As used in university and college real estate licensing programs, this text clarifies the application of state law. Chapter 10, "The Real Estate Business," explains that when licensees buy or sell their own property, they must disclose their license status at the first contact, which includes advertising. This is a standard interpretation of the disclosure and anti-deception rules.
