Hey Trizia, check out Mont Sky in NYC. They were open to my friend selling his place without some sort of commission split, since he worked there. Not sure many other brokerages would allow it.
I would highly recommend that you start out at a firm that offers you not just training, but leads and referrals to work on, perhaps with management. Even if it's working on a team, you can view it as real world training.
I have a friend who recently joined Mont Sky Real Estate in NYC, and he's been assigned on 3 exclusive sale listings in Manhattan within 3 weeks, plus numerous buyer clients he's working on with the Principal Broker. Basically it seems like real world training.
Would definitely recommend you get working on a real sales deal as soon as possible. Otherwise, there's little chance you can succeed with no deal history against all of those sharks out there!
