So it is like a car transaction in terms of title.But based on the integrity of the numbers involved it should be treated like a real estate transaction.

That would include you or them acting as a third party facilitating a real estate transaction between two other people.If you are only buying properties for yourself to flip or whatever, and these appointment setters are your actual W2 employees and not 1099 contractors, then you are probably OK.If you're a wholesaler and don't intend to take possession of the property, well that could be completely different.As always, I would advise spending a few bucks to talk to a real estate attorney on matters like this.
