While your facts are limited, and this forum is not conducive to discuss all the implications, I am not sure why you are considering using this structure. I am sure that you could utilize another structure that has fewer complexities to accomplish the same result.
The DST has numerous requirements one of which is that a trustee must be a Delaware resident. So if you are not a Delaware resident, you will need to use a Delaware Trust Company to act in this capacity. This adds additional cost.
For federal income tax purposes, the DST can be treated as a grantor trust. Essentially this means all activity of the DST will just flow through to your 1040. The DST will, however, need to file a form 1041. This also adds an additional cost.
Please do seek some legal advice before venturing into this arena as I seriously doubt that this is the best and only entity structure to achieve your business goal.
