@Chris Klaude some beginners tend to try to take in too much information, reading too many books and articles, watching videos, attending seminars, etc...that it becomes overwhelming and eventually build doubts. The longer you put off getting started, the more fear builds up inside you. You start having questions and thinking twice. Don't get me wrong, learning by reading and watching is already getting started but if you spend too much time on it before taking action, that's a different story,
If your gut tells you to start with Wholesaling then be it. You've heard them. Those people you heard and read about had their reasons why they started with Wholesaling and they found success in REI eventually. The only real money you'll need if you start this way is for Marketing. You can do it on the side and not have to leave your full-time regular work. You don't have to have good credit. Plus it seems your heart tells you its the better way to begin. Then do it already.
You can learn from all the best teachers as much as you want but you will never fully know until you try it yourself. It will never be perfect and yes, you will have mistakes. But start now while the passion is there. Build it up. After getting better at Wholesaling, save the money you make and learn and build on bigger and better forms of REI. Set goals but worry about the rest later. Just take it one at a time. Focus learning on what's in front of you right now and take massive action.
