The discounts and rebates offered will vary massively between projects and owners, there is no fixed hard and fast percentages or strategy with discounting. It ultimately depends on the specific personal circumstances of the individual selling the property (when did the buy? Strength of currencies then versus now?).
Many developers are able to offer reduced transfer fees, or include partial furniture and add-ons versus discounting the actual sales price.
This is one key advantage of working with an agent who knows which sellers and projects are more open to these offers and discounts.
At FazWaz we are able to negotiate group buying or bulk-discount offers on specific projects where we sell large quantities of units or where we have exclusive rates and prices agreed for pre-launch projects. Contact us to be added to our pre-launch promotional database where FazWaz buyers get access to new project launched before the general market.
