You need robust escape clauses that you explain to the buyer ahead of time.  

I often come across multi family deals that i know are profitable but explaining the concept of investing to the everyday individual is like i am talking another language.

@George Despotopoulos , can you explain more about the legality of your firm?

If you would recommend someone, would you please be so kind to explain what drives the referral (e.g., personal experience, general reputation, etc.)Thanks !

@Brian Gibbons thanks very much for explaining a bit more.

Your only out is to either evict them on legitimate grounds or, when their lease is up, you explain that they need to reapply to meet your basic standards to move into the unit.

I did explain my position to her from the start being that this house  is not in my area of investments but offered what help I could provide. 

If you'd really like to speed up the process potentially without spending more money, you can call the Plaintiff's attorney and explain to him the urgency of getting this sale approved (ex. deteriorating property, etc) and obtain a timeline from him. 

You might also explain to them that it's coming, and that if things are paid in full within the time frame specified you will be happy to stop the process.

Would be easy to read about it than have me explain.
