5 roomers are richer people. they don't surf forums.. lol
stated in the brochures and downloads from HDB site mah... the step by step for BTOs.
after selection, around 4 months, they will tender for contractor to build the project ( i may be wrong about the tendering) but once the selection exercise is over and the contractor is confirmed, they will ask us to go sign the agreement of lease, pay 5% deposit if first timer, then 5% upon getting keys.
if not first timer, will pay 10% straight. apart from deposit, need to pay other misc fees, stamp and legal fees. then also must get the HLE ready by then.
