I'd be sending copies of the video to the car rental company and insurance company, so they also have proof it was the guests' fault. 

RANDOME people.

Here's a good video analysis of the bill I just found: 

For what it's worth, some ideas I've seen pitched are grocery bundles (e.g. a breakfast bundle for 2-4 people with eggs, bacon, bagels, cream cheese, and OJ all pre-stocked in the fridge), meal kits, a pre-stocked drink fridge, charcuterie boards, premium coffee selection, bike/e-bike/scooter/kayak/canoe rentals, video game consoles, upgraded work-from-home office amenities (e.g. oversized computer monitor), etc.I'm not a lawyer, but cocktail kits, bottles of wine, local craft beer, and other alcoholic items seem like they would fall into a grey area from liability perspective. 

Peter - I would start by reading a few multifamily underwriting books and watching a few underwriting videos on YouTube.

What I have seen more and more is random fees getting thrown into closing statements.  

@James Wise The owner of Holton Wise Property Management (a very large very well respected property management firm in Ohio) has tons of examples of this on video on his website.

You aren't going to buy a course and then randomly become rich.

Also, consider that this person may not wish to be stuck with random roommates when you move out.

You arent going to estimate anything from a video .
