Salesperson license in MA solely for investment purposes: broker?

[Dmitriy Pukhov]

It is my understanding that a good amount of investors start off as real estate salesmen. In this case, how do you go about keeping your affiliation with your broker, after you decided that fulfilling their hourly requirements is not in your best interest any more (i.e. you want to focus on investing only, but still keep your affiliation active)? 

Plus, how does commission split work for you in this case? Is it possible to pay flat monthly fee only, and be able to keep the entire commission for yourself on the properties you buy for yourself?

In my situation, I received my license in MA solely for the purpose of expanding my possibilities of real estate investing (MLS access, ability to save on commission etc.), and now I'm trying to find a broker to get affiliated with. Having to deal even with 70/30 commission split on my own deals doesn't make much economic sense to me.

Any advice (especially local) would be greatly appreciated.
