She should inform any buyer that she is a licensed real estate sales agent acting on her own behalf—either in writing before entering into a sales contract or by disclosing the information in Paragraph 4 of the sales contract. This disclosure is required by TREC rules.
The Code of Ethics outlines similar requirements in Article 4 and Standard of Practice 4-1. In addition, Standard of Practice 12-6 requires REALTORS® to disclose their status as owners or landlords and as REALTORS® or real estate license holders when advertising unlisted real property for sale. Similar rules apply when license holders intend to acquire property on their own behalf.
These disclosure requirements are intended to ensure the public is informed of an agent's license status when buying real estate from the license holder, and to avoid claims that a real estate license holder was using her undisclosed license status and expertise to take advantage of a member of the public.
