Did my 1st resale appt on 26th Nov. The 2nd resale appt is normally 6-8 weeks according to the HDB officer and my agent. So we booked 7th Jan for 2nd resale appt, which is about 6 weeks later. But we were lucky because the owner actually allowed us to start renovation immediately after our 1st resale appt, cos the house is vacant. Just need to sign some indemnity form.
