For most securities offerings that allow unaccredited investors, you must have a pre-existing relationship with the “issuer” (syndicator) before it can offer you an investment opportunity. Your best option if you don’t meet the accredited definition is to reach out to some syndicators directly and develop a pre-existing relationship so they can invite you into a future Rule 506(b) deal.
Some ways to do this are to:
1) Ask securities attorneys to introduce you to some of their clients who do 506(b) offerings;
2) Reach out to some of the syndicators on Bigger Pockets or other forums and get to know them offline; or
3) Reach out to some of the crowdfunding platforms (like Crowdstreet.com) that can introduce you to some of their clients who do 506(b) offerings.
