Dear Strawberry,
Never knew many many people have this problem! My OTP on 30/01/2010 & exercised option 10th feb, only submitted to HDB appli 26/03/2010 (cos seller hv to find a plc to 1st - i was agreeable & gv 90 days,thus the late submission), my 1st apmt 20 jul
did HDB allow you to change the 1st apmt date? Your seller agreed to it?
Do NOT allow them to extend, theres alot of risks involved from what i have read on this forum
