Yes, a real estate agent can legally and ethically sell their own house without violating any professional rules or regulations. However, they must disclose that they are representing themselves upfront in the deal and must act in their client's best interest. Additionally, they must be aware of any conflicts of interest and must properly disclose them to all parties involved. It is important to consult with the real estate broker and review the state laws to ensure compliance with all regulations. While a real estate agent can sell their own home, it may not be as easy as just getting a real estate license, as buying and selling real estate takes a lot of time and patience regardless of one's level of expertise.
