During negotiations a Seller said "Im not a sophisticated Investor"

[Devin James]

“I’m not a sophisticated investor.” Is what a Seller told me a few weeks ago during a call negotiating his property. 

He wants $1.8M and I told him its worth $1M, but I pitched a JV structure that would be able to get him is $1.8M.

Should he have said that?

I liked the honesty, it was a reminder to slow down, explain more, and prioritize clarity.

If you were the seller, would you have said it?
How would you have responded as the Buyer?

Was he just playing mind games?
