That's why Y Combinator has an interview process. Why venture capitalists do due diligence. Why coding camps start with a test to see if you're worth educating. And so on.
The incentives for fraud are also why many variations on this model involve putting a visible investment into you, but without necessarily paying you directly.
If an advisor is willing to accept the potential for perverse incentives on the part of the advisee, that's strong evidence that the advisor is confident about their advice.
If the advisor expects the advisee to accept the risk of perverse incentives on the part of the advisor, then caveat emptor.
There may be good reasons to structure the relationship that way. For example I expect to pay a lawyer, and usually I don't expect to receive financial gain out of the relationship. But conversely it becomes very important for me to establish that this lawyer seems like a good one before I pay too much.
But it all boils down to the same thing. I should be more inclined to trust offers to share in my future profits than offers have me pay now for an uncertain reward later.
In otherwords, you can lead a horse to water, but you can't make them drink.
I agree that a business, like YC, that has been around for a while, monetizes directly with a fee-for-success model, and has good reviews is very likely to be effective. But the inverse does not hold: a program using fee-for-service is not particularly good evidence that the program is ineffective.

There are challenges with a pay for performance model, but a business that successfully operates on one is sending very strong evidence that they are actually effective.
A fee for service program may or may not be good, but the burden of proof is now on the company that they are worth what you'll spend on them.
I have no knowledge of if the individual involved is credible but in broad strokes, I do love to see it. It's exactly what btilly said. If this guy is actually so good at teaching people to make money in real estate, he should want to fund people to use his advice, not the other way around. Apparently, he does.
If these "masterminds" actually offered effective advice, then the best way for them to make money is find likely candidates, PAY THEM to take the advice, and then GET PAID a share of the success.
Sounds ridiculous? It isn't. A wide variety of businesses do some variation on exactly that. For example this is exactly what Y Combinator does. It is how coding camps work. You can find interview coaching that works on the same principle - they get a share of your first year's salary.
But if THEY ask YOU to pay THEM, maybe the advice is worthwhile and maybe not. However their business model should not inspire you with confidence.
