CPPDSM4009 Interpret legislation to complete work in the property industry

Property Management Course:

You are conducting an open inspection of a property on the market for $530k when a visitor approaches

you and asks whether an offer of $495k will buy the property. You advise them that the vendor has already

turned down offers above $495k (even though she hasn't) and therefore the $495k would not be enough.

A few minutes later, the same visitor approaches you and asks you if $510k will buy the house.

Question : How would you respond to the visitor's 2nd approach of $510k?
