Suggestions on negotiating the seller down

[Diallo Jones]

Hello BP community,

I need advice on negotiating a seller down on his price. I hit a few key points while talking to him such as how much he plans on making after he sells, and he told me he put his own personal money into the project so I know it’s kind of emotional with him. I need to get him down $15k from were he’s currently at. Any advice on what I can say to him?
