Seller put me in a tight spot, what should I do?

[Shaquan Whitaker]

So I'm a wholesaler in the Springfield, MO area. I was driving for dollars and came across several FSBO's. One seller in particular (elderly lady, getting too old and was a landlord) has a property for sale that is in great shape. She told me that once she signs the papers, she wants the deal to be done. She doesn't want me to list it, or sale it to a third party, she just wants it to be where she sells and I buy and that's the end of it. As a wholesaler, you see where this can be a problem for me. I don't want to lie to her, or go behind her back. Any suggestions?
