Bro，you must be very new to IOI property then, they are the only one can afford to do that since many years ago, they are already like that.
it still don't change.

other than see hoy chan, go find out in the whole malaysia, which property developer will only start selling
their condo or apartment after they reach to 4-6 floor ? most project are are sold this way, not like the rest of developer.
start selling when pilling not even started. IOI start selling normally when they reach to 4 or 6th floor.

So, you can imagine their people are those, u want buy u come.. u no buy i can still wait... attitude.
