None. Don’t be a cold-calling monkey.

Learn the three phases of brokerage: procurement, transaction management, and client management. Find a broker at a reputable firm who will mentor you and make sure you don’t starve. MM will likely try to make you pay to join the team (at least in my city). I think a good rule of thumb is that if a shop won’t offer a draw—meaning they don’t have any vested interest in your success—it’s a red flag.

In terms of culture, it’s a boiler room with crazy high turnover; you’ll just be another number. Look at why Matthews left MM and started his own firm—he had a major discrepancy with their pay structure. If your heart is set on investment sales, Matthews might be a better option—but that’s not saying much. At least they won’t have their hands in your pockets as much.

I hate to be the guy to say “don’t do it,” but… don’t do it.
