You can easily report them to the regulators if they do something fraudulent and can pay fines and/or have their license revoked. 

Didn't make a lot of sense to me, but sometimes regulations don't make much sense.

>If you rent that out without a true Certificate of Occupancy, a tenant can sue you for ALL of their rent money back. show me any law/regulation that states this.  

Short-term rentals like Airbnb can perform well in tourist-heavy areas like Vegas, but be sure to check local regulations.

Also, it goes without saying that if you make a procedural error (very likely as the process is designed to trip up the unsophisticated landlord, and all tenants have the right to a pro bono attorney), then you have to start the process again from scratch. 

So thats kind of the standard operating procedures in those markets and nothing really sells for full list price..
