"Can you tell me about why are you looking to sell your property?"
Then shut up. You'll learn almost everything you need to know from this question. Resist the urge to interrupt.
"Is there anything else I should I know?" at the end of the discussion is also a favorite of mine.
@James Cloud "Would you sell for what you owe?" Is my personal favorite.
@Will Gaston thank you duly noted especially keep shut👌
@Doug Pretorius thank you I will be holding onto that dime you just gave me. Duly noted!
