Those are horrible terms! There is 1000's of syndications and crowdfunding deals that offer 8% pref with a 70/30 split or better. (with the investor getting 70% after the 8% is paid and you receive your return or capital). I am in deals from 15% preferred 50/50 to 8% pref 90/10. 5% is a typical management fee. I would run not walk away from this deal.
Also read the ppm and find out what all the gotcha fees are. Asset management fee is a favorite that can kill your returns if not structured fairly.
@Ian Ippolito, I talked to them today and had a few questions answered. Basically, from what I'm told, even after the property is refinanced, investors will very likely still have money in the deal which means the rental share would stay 75 investor / 25 them. The only way this will supposedly change is when the property is sold or if there's a second refinance of some kind where the investors are cashed out completely.
No one can post syndication deals unless they are 506c offerings. Otherwise they have to have a relationship with the investor to present them. Real Crowd and CrowdStreet are the 2 largest 506c platforms that list online syndications...ie Crowdfunding deals. They put up at least one a week.
