I believe also in the CBS5 raw video, she mentions (after being instructed to do so by LR) that taking in Hassani was his idea. She also mentions that he was the one who got the house, and that he "paid the security" or something to that effect. In context, it seemed to me she was talking about a security deposit required upon beginning to rent a place.
Have we confirmed LR actually is the owner? Perhaps the house sold to a different owner, who rents to LR & JC? That might make the financials make a bit more sense.
I don't think we've actually confirmed who owns the house and I'm not sure there is a way we can do that. It certainly makes more sense that they would be renters, vis-a-vis their apparent income situation!
