Off market deal- how can seller lessen tax burden selling to me?

[Jedd Braunwarth]

Alright experts need some advice. I have an off market deal I am buying from a seller, roughly $1.8mm, we had many conversations, toured the property, etc. The owner is wanting to fully retire and move out of state and as of Tuesday we left our last meeting with both of us agreeing we could make this happen. He called me yesterday as he unfortunately did not talk numbers with his CPA and was surprised by how much he will pay in taxes on the sale to me. Outside of offering more money to purchase is there anything I can present to him that would help him cash out and go into retirement? I mentioned seller finance deal and he is considering but can I sweeten it somehow with a certain structure? Is the Delaware Statutory Trust an option if he wants to reinvest somewhere else and just not have the headaches of managing?
