@Zac Lindquist,
Ok, so you're just now considering taking the plunge. As you can see, not everyone thinks highly of wholesalers. They see us as predatory, dishonest, and all kinds of things like that. And to be honest, for good reason. There are definitely wholesalers out there that fit that description.
If that's you, do everyone a favor and find something else to do. If it's not, the get ready for some hard, honest work.
First, you need to learn how to wholesale from the start of the process to the end. I recommend the book, "If you can't wholesale after this... I've got nothing for you." It's an easy read that does a pretty good job of explaining the process. Once you've read that, continue to learn as much as you can. Listen to the podcasts, watch the YouTube videos, read audio-books (my fav), and become active in your local REI community.
Since you asked about money, you should know that (in the words of my late father, who I'm sure stole this from a more reputable source), "There ain't no free lunch." If you want to make money, you need to pay for it. You will pay some combination of time, money, and effort. But you get to choose what combination. For example, marketing (the biggest part of the job by far) will take a lot of this. You can send letters and postcards. That will cost money. You can start making cold calls. That will cost you time.
Start first with learning. Understand that this is a long-term, significant commitment. If you decide then that it's worth it, then go for it.
Good luck!
