I've been speaking with Jeff Greenberg at Synergetic Investment about participating in a multi-family syndication they are currently fund-raising. Please PM me if you've invested with them, I'd love to hear about your experience.
I have never invested with them, however, they're the Santa Monica meet ups moderators most of the time.
Based on the deal stories they share - they know what they're doing.
You can always meet them face to face and ask for references
