Done it few times oredi me....seriously no harm one la...i always put in low low offer px range....if exceed my range n 100% of the times it is, den i decide to go ahead anot lor....
Buy new launches advantage is u get to buy ur choicest choiced units....if not y pay more compared to resale n goto wait 3-4yrs....
So if u dun submit chq, u will not get the best stack n high flr unit.
Even during downturn, aso goto submit chq n rush down...wharf res and lucida for eg.
caspian and mi casa also....for mi casa, i refused to submit chq n ended up cannot get any high flr park facing units...anyway no regret bcoz px din increase much...hehe
