I could train anybody to fully understand sub-to including all the risks and rewards in about 2 hours... for $0.

Reward.

Never really made a nickel from CF, but a humbling reward when we finally sold!

Flipping can be risky but also highly rewarding.

However, multifamily properties may offer more considerable long-term rewards if you're ready to take on the challenges of maintaining numerous units and are interested in gradually creating a larger revenue stream.The optimal decision ultimately comes down to your own investment objectives, risk tolerance, managerial skills, and the particular market dynamics of the regions you're thinking about.

And there is a wide spectrum of syndication strategies that span a wide spectrum of risk versus reward.

You are taking a monumental step towards a really fun and rewarding future. 

You can do both.What is your risk/reward level?

With flipping, its a high risk /high reward thing... and the downside as well..That's fine if you don't want to be a landlord (other than str). 

I'm wrapping up my first duplex house hack in DFW (selling off-market now) and it's been by far the most rewarding experience, so much so I'm transitioning careers to get more involved in RE!
