Doubtful. Existing tenants/sub-tenants, unless somewhere stipulated in a lease agreement, are not going to be summarily kicked out.
The bigger threat to anyone who takes over Trump's properties is this:
1. The existing tenants and subtenants have an "escape clause" in their leases that allows them to move out if the Trump Organization is no longer the owner and/or the building is no longer named "Trump Tower."
2. The Trump Tower property has a binding agreement in place that says it must keep the name "Trump Tower" for a period of time that is likely measured in decades.
3. Donald J. Trump has a binding agreement in place that says any future owners of Trump Tower must pay him an annual licensing fee of $500 million to keep his name on the building.
Go sort that out and see what kind of nightmare a hostile takeover of Trump Tower might entail.
