Hi @Rocky Griffin
I just find this on a website, probably is going to help you.
"What Qualifies?
Property held for productive use in a trade, business or for investment may be exchanged for like-kind property. For real estate, like-kind property is widely defined as real property located in the United States and some of its territories. A single-family rental can be exchanged for a duplex, raw land for a shopping center, or an office building for apartments. Any combination will work.
Real property and personal property are not like-kind to one another. A commercial building may not be exchanged for an airplane, a single-family rental for a licensed timeshare, or raw land for heavy construction equipment.
Personal property is evaluated based upon its nature and character, its General Asset Class, and NAICS classification. A school bus may be exchanged for a metro bus, a barge for a tugboat and a fleet rental car for a taxi."
