Step away from this nonsense.Unless she has a source of income to actually buy this, that she hasn't declared to the local housing authority, I will bet that she wants to use her Section 8 deposits to  you to purchase the house. and if she hasn't declared her extra income to section 8, then she's just defrauding the system.You can either say "no" directly to her, or just say that you still have a mortgage and you can't enter into a lease purchase agreement for at least another 12 years.

I'm betting about 80k or so mortgage aside.

What's my best bet in convincing the seller he should finance the deal?
