Answer to legal wholesale aspect before beginning resesrch

[Victor Mercado]

I have recently gained interest in wholesaling.  I started doing a little research when I came across the legal aspect of it. I am in Mobile, Alabama and can't find anything telling me if it's legal or not here. Maybe I'm not searching correctly or the answerr is front of me and I don't know. 

I only known the basics which is being the middle man between seller and buyer for a few. I wanted to figure out if I could do that here legally before doing tons of research. If indeed it is legal I am pretty determined to be VERY great at it.I have never been more serious about something in my life. THANKS in advance.
