First, I knew it was a pre-foreclosure so I knew there would be a lot of emotion involved.

@Thomas S. your right I need to take the emotion out and stick to my standards.  

You both are using 50% of the building.If market rent on the property is $1,000/m, then she pays $500/m.Don't let the emotion side of things get in the way.

There are too many swirling tornadoes of vague fear and failure that go on in this business and too many smug self-congratulatory types who never get tired of patting themselves on the back or putting you down, and preferably (for them) both.I know the jargon at the auction can be overwhelming.

Take the emotion out of it.

I read about how "easy" it is to get a pet for this kind of emotional support.

Is it from emotional fear, or calculable risk that can be mitigated? 

There is logical and there is emotional.

I feel that I want to help her since she is such a great tenant and maybe I could do a better job since I'm not emotionally influenced, but you are absolutely right about this resonating more strongly coming from her.

I think that this thread will help anyone who is thinking of renting to someone they know or are related.... still do your due diligence and take that into account before you make an emotional decision!
