Getting Licensed for Rehabs

[KJ D'Costa]

I'm contemplating getting my R.E. license to make my rehab deals more profitable. But I'm unclear on the broker/realtor structure. If I get licensed as a realtor, I have to sign up with a broker in the area, correct? And if I decide to purchase a home with the intent to rehab, in theory, I can keep 3% of the sales price, both when I acquire (if listed on the MLS) and when I sell, correct? But a percentage of the commission goes to the broker? If so, what's the customary split.

And if I acquire a deal off-market, how does my license affect the sale?

Lastly, because I don't intend to become a realtor as a profession, do I have to sign up with a broker or does the law state otherwise. I'm Texas, if that makes a difference.

Thanks for any clarification?
