Seller having second thoughts.

[Dominique Coleman]

Hello to the brilliant people of the Bigger Pockets community!

My name is Dom and I am in a bit of a predicament. I am wholesaling a house and the foundation of the house is in bad shape and the value of the house is only worth about 50k. The seller wants 11k for it but it is clearly not a house worth fixing up because the house is caving in and the buyers I have for that are will only pay 5k for the house and an assignment fee. He wants to tear down the house and build a new one. How do I convince the seller to agree on the price of 5k?
