@Mike Martin A few insights on the mechanics of the DST Industry that will help:
1.) "DST Sponsors" are the investment companies that purchase and package the real estate as a DST.
-2.) DSTs are securities and are registered with the SEC.
3.) You can't purchase a DST directly from a DST Sponsor, you must use either: a commission based Broker-Dealer (BD) or Registered Investment Advisor (RIA).
I would recommend that you use a RIA. Full transparency...I am biased as my dad and brother are wealth managers and provide advise on DSTs.
You want to work with a RIA that can help you understand how DSTs fits into your overall financial picture and not someone that's just looking to make a commission off of you (aka Broker-Dealer).
Both BDs and RIAs are going to able to offer access to the same DSTs, but there are several conflicts of interest associated with the BD sales model....(happy to elaborate more if you'd like)....but the biggest issue I see is that you end up paying 2X more when working with a BD vs a RIA that's acting as your fiduciary.
