Seller's ask price is their lowest?

We know someone who sells houses and does not use an agent. He knows how to do that themselves and has a closing attorney. In a conversation about one of their many properties they threw out $110K on a 2 BR home built in 1940. 2 BR but an extra room for a 3rd or a dining room. Yes everything looks fine inside and out and the only thing that might "date" the house was a small closet in the hallway that had the original door and door knob. Then they had to add on a new back porch and were very eager to tell about the soundness of the floor of new add-on as compared to a spot in the kitchen floor. We will of course visit again and see more about some kitchen floor movement on one spot. And the living room floor is painted brown. How far do you think this seller is above the lowest they would take? Yes we know about comparisons and such but this seller prices his own independent of them. The one next door to us which is a 3 bedroom got this seller $82K. We hoped the 2BR was in that price range of say $80-$90K. We can not make and offer and be prepared to walk away. This is the property we want pending inspection, seller disclosure etc. In fact they may not even use seller disclosure forms.Thanks.
