Noooooooooo not more house questions....
I wouldn't pay it. You're giving her the house (presumably for nothing) and all the posessions in it (presumably for nothing). She's soooooooo getting the best deal out of this, let her pay for the damn mortgage!!
Remember a post a month or so back where I reminded you that you had balls?

Is the mortgage still in yours and your Mum's name?
When is that being transferred over into her name?
