In my devious mind, I thinking like you that I hire a parking attendant, install gates and charge an entrance fee if I bought it. 

The "fine print" here is fairly sizeable upfront fees and high interest rates, relative to a traditional construction loan from a bank.  

Also, I assume a 10% property management fee in my calculations and based on initial conversations.

If that's the case I would strongly suggest building your team before pulling the trigger on an Airbnb.

No Chilling in their plans or pulling up on the gas.  

Forget about the late fees and payment plan, you'd be lucky to find any judge who would enforce it when the tenant showed they weren't even living there any more and were still doing their best to pay off the balance. 

You should never pick your 1031 Exchange Qualified Intermediary based solely on their 1031 Exchange fees, costs and charges or the size of the institution.

Only thing better would be initial deposit and then paid in full upon Certificate of Occupancy and punchlist complete.Of course, standard items should also be checked: licensed, insured, willing and able to pull all required permits, reference checks.I would also commonly avoid the cheapest bid you get.  

Please let me know who you have worked with and why you like them (How many properties do they manage for you, how long have you worked with them, what you like about them etc.)When the unit is vacant, do they cover the cost for professional photography to rent it out again, or is that an additional fee? 

You're buying a trailer and a tenant pays the lot fees.
