Texas Realtor Brokerage Question: Fulltime vs part time

[Victor Mondragon]

I currently have a full time w2 sales job in which I office from home.  I am working on my first real estate investment deal now, and am hungry for more.  I am interested in getting a real estate license but I don't know if its possible to be successful as a part time realtor.  

Questions for all of you realtors out there:

1. Do brokerages frown upon part time agents? (Especially those that work full time)

2. Is it possible to be a part time REA that focuses on investors?

3. Are there certain types or sizes of brokerages that are more open to bringing in a part timer?

My goal isn't to be the "let me help you buy your next home" type of realtor.  I am more so am interested in finding deals for real estate investors as well as for myself.  I am not interested in wholesaling.   I don't know much about the licensing process in TX, but from what I've read it seems like you are at the mercy of your brokerage. 

Thanks in advance for your answers, general thoughts, and feedback.
