Its very common for the sales/project manager to 'play games' with their devt - controlling Who, Which, What, When, How and even Why units are being sold. One day you go there, they tell u 80% sold,..making u kan cheong..the kan cheong spiders will quickly jump in. next day you go again, they say 20 more units released. When you enquire about a certain unit, they say "sold" when in fact its still avail; making you buy the less than desired unit for fear it will be sold too. Some developers play more intensely while others less. Its happening everywhere not just HH. Even SG included, so no way to avoid. Its a way to drive herd mentality and push up sales and prices.
Far East Org No#1 in this game.
I live in the east and have seen them play this game with Silversea, Dunman View, Shore, Cape, Sound, euHabitat. All strategically placed and pushed in tandem... although UEM & Gamuda far from that, they are learning fast.
Key is be disciplined and know what you want and know your own budget realistically...
