If you are doing #1-3 having never tried #4, better get a darn good referral from a disinterested 3rd party whose only affiliation is having a long track record of successful investments with the provider/sndicator, since you will not be a good judge and will be entirely reliant on these "boots on the ground".

(DISCLAIMER: I am not affiliated with nor do I receive any compensation from yellowletters.com, but we are a customer of theirs.)

Thought it was just a random house the realtor had no affiliation with!

I'm in MD and mine charges a flat fee of $500 for contract preparation, but they offer a $200 discount if I close with the title company they are affiliated with, so it would be $300 if you ultimately close the deal.

I have no affiliation with Amica.

Learn real estate before trying to deal in real estate.Your insurance agency is a great affiliate operation to real estate, be even better if you got your RE license!

NOTE: I am not in anyway affiliated with this company nor receive referrals for recommending them.   

For TMLS (Triangle area), try for example http://realestate.luxurymovers.com/search-city.php I have no affiliation with this site.

Would this allow the platform to receive commissions for successful capital raises without affiliating with a broker dealer?

So far the people I've worked with affiliated with the site have been pretty good.
