I'm a bit slow here, I don't quite follow this, so if you save them $4000, then they have to pay you $4000... so they don't actually save anything?
Do you show them a few valuations of similar properties and say this is what I think the property is worth, and if I buy it for $X amount I have saved you $X money?
Or is the saving relative to the asking price?
What if only a price range is given?
+1 this is the bit I don't understand as well.
