@Reginald Ross @Taylor L.
Agree with both comments. This is definitely a process. Assuming your friend does have a significant amount of experience in the space (using their own money first), then most people start out with a "friends and family" syndication and slowly grow from there. @Taylor L.
I could be wrong, but I am not sure most people use S-Corps. to hold syndicated real estate projects, so I would look into that further. I am certainly not giving legal or accounting advice here, but S-Corps. tend to be very rigid in their requirements, more so than, say LLC's. Your friend should consult a good real estate attorney and CPA.
There are a number of seminar based real estate guys out there who teach this stuff. Michael Blank is one of them. There are several others. I have not taken their courses, but we do work with a number of their students and most seem to teach reasonable strategies. Definitely a great starting point.
I hope this helps.
Warm Regards,
Ken
