Hi John, I can give a brief high level overview.
A Delaware Statutory Trust (DST) is a passive investment vehicle that is generally used for real estate investing. The major advantage DSTs have over many other types of passive real estate investments is that they qualify as replacement property in a 1031 exchange. Because of this, 1031 exchanges make up the majority of all DST transactions. Large sponsors have multiple offerings open at a time so investors can choose a property type that fits their goals. Apartments, Student Housing, Self Storage, Commercial, etc.
The SEC classifies a DST as a security so they must be purchased from a financial advisor.
The costs very A LOT by financial advisor and DST Sponsor. In general, financial advisors that work for a Broker-Dealer charge 6.5% on the front end. In my experience, financial advisors that work for a Registered Investment Advisor charge about half of that. The DST sponsor takes about 2% on the front end as well.
The hold period is generally 2-7 years. At that point it can an investor can pay the taxes, 1031 to another DST or 1031 into any other type of property that can qualify as a 1031.
The rates vary from sponsor to sponsor and differ over different periods of time. A very large DST sponsor I talked to recently told me their average return after all fees and commissions has been 9% overall and 12% for multi-family and student housing. Cash flows are generally paid out monthly to investors and right now I am seeing distributions around 3-5%. (So, if you've got a million of equity you're exchanging into a DST, you would expect $30k to $50k per year). The rest of the return would be from price appreciation when the property sells.
The main tax benefit is that they qualify as 1031 replacement property. Second, they are tax advantaged just like normal real estate with annual depreciation. It just shows up on your schedule e like a regular property.
Other benefits are: limited liability/asset protection, reasonable minimum investment ($100k usually).
Note that these do have risks just like any real estate and they are only available to accredited investors.
