Eventually though it sounds like you will buy this 4 plex and I think because you will both be living in it, it does involve her being at least somewhat on board.  

This keeps coming up and I already accepted her being a foster mother but now she found away she could get more money. 

But I was in crunch of time having being out of town and back to lend her the key and her being a Teacher I kind of trusted her. 

As far as her being humiliated in front of her kids, well she should get it together and pay her rent, and her kids should understand that when you don't pay rent as agreed you get kicked out of your rented house.

Even slightly overpaying, means you have vaporized the "savings" of the realtor fees.3) Appreciation is good and we probably have a couple more years of it on the way.

Start off on the right foot with her.

Let her be difficult for the next guy.

Funny thing, there was a broom covered in plaster on the floor next to her bed. 

My tenant was in a little studio and she sectioned off her bed this way. 

Is it herb?
