(2) DISCLOSURE OF MATERIAL ADVERSE FACTS. A licensee may not exaggerate or misrepresent facts in the practice of real estate. A licensee, when engaging in real estate practice, shall disclose to each party, in writing and in a timely fashion, all material adverse facts that the licensee knows and that the party does not know or cannot discover through a reasonably vigilant observation, unless the disclosure of the material adverse fact is prohibited by law. This provision is not limited to the condition of the property, but includes other material adverse facts in the transaction. Note: Certain "material adverse facts", as defined in s. REEB 24.02(12), may not be disclosed by law. For example, unless specifically authorized by a seller, a licensee may not disclose to a potential buyer the actual minimum sales price the seller will accept. See s. 452.133(1) (d), Stats.
