My job as agent is to educate clients and then help them mitigate risks.There are a number of outside risks that could threaten an investor portfolio. 

He has spoken about bringing his gun out to threaten our neighbors barking dogs- well he’s not allowed to have guns per the lease but there’s no way I can prove that he told me this!

However, buyer threatened to sue due to non-performance.

Unfortunately he had horrible life threatening health conditions that took his life in 2020, but his biggest wishes he talked about before he passed were that his kids and grandkids be well taken care of and that they always have a place to live and lastly since I was taking my real estate classes required to obtain your realtor license at the time, he said to me "Kelly, I want you to sell my house when you all are ready and only you can be the realtor on it, only you, you're in charge of that, ok?"

Tell her to get a restraining order against him if she feels threatened. 

If they fail to leave or get threatening (even by text) then I would call the police and ask for a visit.

Sounds like she is not really threatened by you, Tatyana.

One thing you want to be very careful with how you do this is how you handle threatening legal action.

I’ve been threatened enough to learn that not every deal or location or situation is worth it.
