Im a fairly new wholesaler myself and could provide a couple nuggets for you.
1st thing 1st. Establish your 'working' time for your business. Daily, weekly etc. If you work a job make this your '2nd' job and treat it as such.
2nd thing no matter what anyone says - you need a little bit of $$ to work with. Establish a budget that will not break your bank. How much can you comfortably spend a month?
3rd you are going to find along the path soooo many shiny systems, trainings, platforms, leads blah blah blah that could be helpful. If it does not fit in your budget do not purchase. It will take some leg work but you can learn everything you need to know about wholesaling, how to go about it, what you would like to 'niche' etc via youtube, BP, and networking.
4th find a cost effective way to get started. (what I did and it works) is driving for dollars. Very cheap and wonderful starting point in getting your hands 'dirty'.
5th Once you have done these things and have some sort of a system going - find a Mentor. You do not need to pay $1,000 and $10,000 for this. They are out there. Make sure you research and interview for this to make sure its a good fit for you both. There are tons of successful people out there that love to help others be successful. The cost for you could be splitting deals which is more than reasonable.
Dont get to wrapped up in knowing everything, figure out the basics, keep it simple and advance along the way. :)
