It depends if the unit is located on the same floor, facing, property condition and other variable factors. If it is located on the same floor, the seller will use the last transacted price as a price guide. The price may be higher or lower depending on the view and property condition.
If it is located on a lower floor, then the price will have to be adjusted accordingly.
In summary, the asking price must be market pricing and should not be too high or too low.
Hope this answers your question.
