negotiation question

[Robert Niosi]

Hi BP,

I recently spoke with a seller who dropped their sale price 14k below the original sale price when I asked for them to give me their rock-bottom price.

I have let it set for a few days trying to decide if the numbers work and they don't. 

They sent me a followup asking if I had considered their price. I have decided it's still way to high to make a profit. 

How would you go about trying to negotiate even lower? They stated it's their rock-bottom but they most likely have no other offers and seem motivated to sell.

Any advice on an approach to further negotiation would be much appreciated!
