If buying for own stay, can buy provided is below market valuation price and not snp price esp for newly vp units.

Depends on the property and location. If good area, less 10- 15% is considered good bargain. Having said that, if good area, bidding can also goes above reserved or market price if someone desperate to own it.

Few years back, I won a new VP property on reserved price which is 10% above snp as a single bidder. Liked the view, high floor and also an endlot unit without neighbour main door beside. Paper profit today based on subsale, I made about 70k.
