I started as a residential broker part time six months ago. I definitely want to pursue commercial in the future but I have a hard time imagining starting out there, especially if you have a full time job. It's much more complicated, there are far more variables, the commercial community is pretty close-knit and it's hard for agents to break into that marketplace, let alone new agents, commercial clients have a lot more at stake and are very concerned about their agent knowing what he's doing, you will probably not make a commissions check for close to a year, and probably a number of other reasons. I tell you, if your job isn't very flexible, you will struggle. even in the residential world. I work a good bit with investors in residential properties and even so, my full time job quickly became a part time job and will soon become a memory. Work hard, work smart, accept the fact that you have a ton of stuff to learn (as do I) and you'll be fine!
