If they are ghosting you, start by taking photos of everything and itemize their bill. 

There are so many good advantages to using the build to rent model.  

This model seems akin to a timeshare. 

I've been interested in that as well.I think best way to start would be to find an agent down there who knows the AirBnb business model and can help find properties that would make sense. 

There are no complicated models to build out.

For anyone interested, here is a 3D model I shoot when the remodeling is in progress:https://my.matterport.com/show/?

For personal reasons we ultimately decided not to pursue this business model, but now we have this property.  

I would assume little to no appreciation over next five years so I would model it and see where it plays out

When an agent send you a video of a property walk through what are key items you are looking out for?

This is the exact reason why I switched to the Build 2 Rent model, and most of my investors are following.
