Yes. off-the plan is very bad for buyers. currently I got a deal signed 2 years to settle in the near future. You do not know exactly when you need settle while you wait for the completion. Furthermore, you do not know whether the bank will finance it and how much loan the bank is willing to give you. For current properties, you could know whether you get finance in a few days and that give you certainty.

Believe me, Developers and their sales people also tend to overprice off-the-plan properties as well.

Remember, never buy off-the-plan.
