Love to see you are in the game and starting to swing the bat! Regarding Rentaus, I have been down that road and yes their training is an investment, but so is any part of advancing yourself in this business. IMO, Renatus does have some great instructors and yes you can learn a ton, but they are also pretty aggressive on becoming a marketer and that in my opinion can derail your efforts as it takes away focus (again, just my two cents and I am speaking from experience in the Renatus model).
You have to decide what YOU want for your life and business first before heading down any path. IMO, you need to make sure that you pick ONE path to start on (Rehabbing, Wholesaling, Buy-n-Hold, Etc...). Focus on that ONE THING and be great at it, learn from others who are doing it, make money at it, systematize it and then venture out into other areas. The biggest problem most newbies have is they try to learn everything the bootcamps, courses and gurus throw at them right out of the gate and then the majority freeze up because they have no idea where to start or what to do first and ultimately do nothing.
Plug into your local REIA and network like crazy!! Find others who are doing what you want to do, talk to them and ask a ton of questions. Ask them if you can shadow them on property tours, talking to sellers, negotiating, etc...
The only way you will fail in this business is if you quit. Good luck :)
