Wow. This is a fun topic compared to a lot of other posts here on BP. I have to jump in.
My advice to you is to stop focusing what others are selling or not selling. Once you accept the fact that everyone is trying to sell to you, you can just take the best parts of what people are giving you for free and decide if you want to invest more. I go into every real estate meeting expecting to get pitched with something. It makes it a lot easier to keep your expectations like that so you can really get the most out of it. Emotional decision making can make you broke real quick.
FYI - I never took a course, maybe bought 1 book. I bought a 54 unit in 11 months with no experience. All the information that I acquired was online. However, I am not saying courses are bad. Every person has a different life experiences, desired time frame of learning, needing hold handing, etc. so a course might work for them. Others have tremendous business experience that can easily translate into the real estate industry quickly. Getting to the finish line is the most important thing. Does the vehicle really matter? Some people need to go to college to get a job, others don't. Same concept.
Side point: It doesn't even matter at the end of the day if you are getting free advice or spending thousands on the course. The people who are going to be successful are going to be successful. I am sure if there were statistics of people who became successful after reading that book or that course is probably low. It's more about the person consuming that information than the medium itself in my humble opinion.
