Where the relevant property has been valued on an open market basis, but such valuation is not by reference to comparable market transactions, the valuer may be required to discuss and disclose in the valuation report the assumptions underlying the open market valuation method in the context of the market in which the property is situated. Valuers may be asked to justify the assumptions they have made in the valuation report particularly where local market conditions or legal circumstances may differ greatly from those in Hong Kong.
