Find a flat surface to put the stickies on.  

David, this is not an ok situation, not acceptable in any form or fashion, No your leg is not a sacrificial lamb, not ok.

I'd start the conversation with something like,  "I guess there was some miscommunication and my attorney said that before we got the police involved, to see if it can't be sorted out in a friendly fashion, so here we are".

In typical lawyer fashion, the most accurate answer to your question is "it depends" (sorry lol). 

But a lot of us aren't focusing on acquiring properties in this fashion. 

Deals are hard to come by right this minute, but if I had to guess, there will be some multi-family opportunities starting to surface over the next few years.

We have seen properties that on the surface look good but either the reno costs were too high or the ARV too low to make sense and passed. 

What happens in the future when the term, "Housing Provider", and the other terms that you replace, "Landlord", with become either offensive or out of fashion?

That being said, they are often designed to prevent things from rolling under the bed and with easy to clean surfaces.

But on the surface, it appears that this buyer is new and uneducated on the risks that come with entering a deal like this.Not a good deal for the buyer, and not a good deal for the seller.
