QI Charge for one DST with multiple properties

[Cathy Zhong]

My QI offers 3 free replacement properties purchase exchange, then they charge fees for each extra properties exchanged.

Now that I will invest in one DST with 4 or more multiple properties. The purchase is only one transaction ( wire the fund to sponsor), Is QI allowed to charge fees for each extra property even though they only do one transaction?

Thanks in advance!
