https://www.budgetdumpster.com/blog/creating-a-basement-apartment/I have attached a link to a website that should assist you in your search, or at least provoke more insightful questions to follow. 

I enjoy hearing his thoughtful and thought provoking questions.

I think @Trent Stone has some provoking questions.

I live in the second floor and my neighbor lives on the second floor.I have not been getting along with my my downstairs neighbors and they have recently been getting very passive aggressive and trying to provoke us. 

Yours may be performing well, I’m not saying it doesn’t, just thoughts to provoke some analysis.  

@Monika MickuteShe is probably a non confrontational person so I would text her her options. also in the text let her know that once filing of eviction starts her ability to rent somewhere else is going to dramatically going to decrease. be empathetic and speak to her about the potential of her kids not having a place to go home to. hopefully this thought will provoke action to call you and help resolve the payment plan. 

And possibly a small percentage.All of these ideas from everyone are very encouraging/thought provoking for me.

Not knowing your particular circumstances here is a brief answer that hopefully is thought provoking. 

Thanks all for the feedback-thought provoking.  

I read a great article recently regarding cash for keys and how its a cheaper and less time consuming process but then it provoked this question I now ask here.
