Using them as a business model (selling property you do not own) is not.

@Jay J. be careful of making such a good defense of your statements why @Scott Trench success' cant be your own or any other person on BP.The case you make might be so good you prove yourself right.This is an instance where you would benefit from being wrong.If you don't like his model for success find your own, spending time on why it won't work is not such a great idea if you want to succeed.imho.

its just so rampant that the states can't keep up. and some states take a completely blind eye to it. if you read the REGS on what is required to bring two parties together on property you don't actually own in a scheme or business model you will see that the definition needs  a license..

Most models are expandable to some degree to fit most any shower.

I am personally testing a similar model with 3 properties in coastal SD. 

A loan is not an old contract for deed arrangement which is also an issue today.What someone might do in one state and in one county shouldn't be a model for private lenders.

The is another show "The Best Passive Income Model"  and tons of others They are all awesome.

At the core of what you are doing is you are creating a sustainable business model that generates income without much of your participation.

I think you need to develop a pricing model and stick to it, and then always be widening your network of sellers. 

This is across various manufacturers and models.
