I made almost 100 crowdfunding investments over the last 3 years. You can see some of the results at my BP blog. 10%+ returns are not unreasonable.

Crowdfunding is pretty much online syndication. Before crowdfunding you had little or no access to deal flow unless you had a superior network or paid high fees to a broker. Thing have changed and you can direct and bypass a lot of fees.
DST's are fee ridden instruments. Google it and see results like this:
Under a DST, an investor is prohibited from entering into new leases or renegotiating current leases. This prohibition adds a layer of complexity, requiring the DST to enter into a ground lease for the property with a master tenant" who in turn enters into may smaller leases with tenants. The investments are also completely illiquid and there is no secondary market for beneficial interest in DST's Assuming such a market even did exist, the sale of a DST interest would trigger capital gains tax- the exact thing investors hope to avoid.
Additionally, in many cases, initial fees associated with investment actually exceed the income tax deferred. Fees paid to the FINRA member brokerage firm or stock broker at a closing also increase the fees related to DST's.
