"Rents.
Rents from real property, including elevators and escalators, are excluded in computing UBTI. Rents from personal property aren’t excluded. However, special rules apply to "mixed leases" of both real and personal property."
I don't rent a personal property and it's not debt-financed.
So, I guess, I don't need to pay UBTI. But I am still not sure if I need to file out some kind of form.
There is no Form K1, there is a schedule K-1 and it has something to do with partnerships.
