Only buy preexisting airbnbs or airbnbs that are registered, but commercially zoned.

Through our local Ground team of Commercial Brokers and Architects.

Any investment real estate will work as a potential 1031 exchange target, including LTRs, apartment complexes, commercial properties, undeveloped land, DSTs and so on. 

Make sure you have " partial release "  criteria  in any loan you might fine ....this might need to be a " commercial loan "..good luck

I am also curious if they even allow it for commercial properties, which LTR and STRs are.

If I have to goto the bank, then the mortgage terms are going to change as it would be change personal mortgage to commercial.

This is a ground-up development coordinated by CC&F (https://ccfne.com/), an operator that has been in business for 120 years and has built over 100 million sq ft of commercial real estate.

When we were done at the notary and finished the purchase, we were able to obtain the license and start the works (it was a big commercial old furniture shop where we created 14 tourist apartments). 

@Cheng ChuAre you looking at residential or commercial?

My wife and I had 5 SFH and 1 multi-family, sold all, 1031 into a commercial RV park, now living for free since other people pay our living expenses.
