Many buyers get swept up on a wave of rising property prices when they hand over their deposit in exchange for a floor plan. Historically, property is a consistent long-term performer, but property prices can plateau and even wane at the mercy of economic factors.

Buyers also need to be wary of over-supply, which may devalue their property.

Make sure you consider the bigger picture if buying off the plan. Research how many other developments are planned in the area and whether any increase in apartment numbers is justified by new or improved infrastructure, such as transport corridors, business precincts, universities or hospitals.
