Is a RE agent allowed to represent themselves in the State of MD?

I am looking to become an agent, and I know there are a lot of factors that feed into this decision. That said, my very narrow question is that if I am a RE agent in MD, can I represent myself when I buy properties? I plan to buy at least 3-4 properties over the next few years and one factor in my decision to be a RE agent is the ability to represent myself.
