Also if you are selling, hopefully your agent has advised you but good practice to have a vacant unit to open the buyer pool to owner-occupied buyers/house hackers.

Any development work they've done on the property also becomes your property.If the property becomes yours, you could try to sell it back to them quickly and below market for a nice profit.

Other RIAs who sell DSTs will provide documentation with their full analysis of each deal they recommend.
