Pre-launch prices are special discounts that property developers offer to start creating interest at the early stages of the commercialization of a new development. The discount is available for a short period of time and for only a certain number of off-plan properties. Normally, during pre-launch prices, the developer has not started land movement on the project and has just applied for a building license; therefore the completion date is the longest expected out of the whole building process.
As new build homes are normally built in phases, what´s key into buying at pre-launch prices is that by purchasing at early stages, you will be obtaining a large discount on what the final price of the property will be. Normally the discounts offered during the pre-launch period are around 25% to 30% of what the final price of the property will be.
Pro Tip:  Purchasing an off-plan property during pre-launch offer, means you have possibility of choosing some of the best properties within a particular development, compared to later stages of the construction when most properties have been reserved or sold and prices have risen.
