I'm not sure if this answers your question, but if you want the security in the qualified opportunity zone business (QOZB) to qualify as qualified opportunity zone property (QOZP), i.e., as a "good asset" for a qualified opportunity fund (QOF), then the security should not be resold or otherwise transferred after it has been acquired by a QOF at its original issuance. There is no rule that treats interests in QOZBs that are acquired from third parties as good QOZP (by contrast, there is a rule permitting the acquisition of interests in QOFs from third parties).
