Agree with @Jeff Filali. There’s no reason to pay so much when it’s out there for free. With the amount you’d pay for one of these seminars, you could already have bought a house and begun your investing career.
I went to a Than Merrill intro seminar once just to see what it’s like. The setup is very suspect. They design the layout so that once you’re in it is very hard to exit. Several layers of people block you from leaving and they lay their pitch out hard.
The man speaking wasn’t Than, but some old salesy guy who look like he made some bad decisions in life. It was sad seeing people respond to his classic marketing calls to action....people would sensationally jump up with a handful of cash (probably all they had).
Between the plethora of podcasts, blogs, books, etc, there’s no reason to ever sign up for one of these. Way better to build your portfolio and then think about how to join a reputable mastermind group who can challenge you to expand your potential.
