For benefits of non-mandarin speakers, the key points by Tony Guru about bulk purchase are as follows:
1. Make sure the bulk purchase deal you entering is in line with or lower than market value of surrounding properties.
2. Perform your diligence on the developer reputation and their track record.
3. Check the profile of your fellow bulk purchasers profile - avoid speculators who won't hesitate to go highly gearing entering such deals - this may lead to future foreclosures and causing a sharp drop in your property value
4. Measure your own head before buying your cap. Don't buy properties which you cannot afford the monthly installment and maintenance.
And lastly, caveat emptors - if the developers offering reasonable deals to the market in the first place, why do they have to resort to bulk purchase to clear their inventories?
Not sure if I agree with all his points (as he darn sure has his own vested interests making such claims - if not mistaken, he's a leader of property agency himself) but some are best kept for own's consideration before going into bulk purchase deal.
Thanks for translating the salient points. Those are valid.
