Liquidity is one of the most important DST considerations.
DST interests are generally not publicly traded on an established securities market. IRS Revenue Ruling 2004-86 itself describes the interests in the DST considered by the ruling as not publicly traded on an established securities market.
Investors should not assume they will be able to sell a DST interest whenever they choose.
Many private placement investments can be difficult to sell, and FINRA identifies illiquidity as a material risk that firms should clearly disclose when discussing private placements.
A DST may therefore be inappropriate for money an investor expects to need in the near future.
