Not sure how to check a syndication for legitimacy

[Evan DiLeonardi]

How do I know if a syndication is legit or a scam? I haven't done one before and met someone through a forum similar to Bigger Pockets that seems legit but at the same time a little too good to be true. I'm not sure how to go about vetting the project other than google searching everything about the people involved and the company, and so far no red flags. Any advice would be great!
