How to convince a person to sell

[Antoine V.]

So I stumbled across a property that will be going to the sheriff's auction on the 2nd of August. The person in just under 10k in payments. He did not realize it was going to auction until I told him; at that point he stated that he wanted to sell the house. He looked on Zillow and came up with a magical number of 250k. Well obviously he is not going to get that; I think I might be able to squeeze no more than 100k out of a hard money lender but that would be pushing it. Is there some mesmerizing words I can throw at him other than "I am trying to help you save your credit and put cash in your pocket"? I would like to pay around 60-80k cash if at all possible.
