The price for Sembawang EastDelta@Canberra BTO 4-room HDB flats starts from $240,000. In the May 2013 BTO launch – Sembawang Eastbank, Eastbrook and Eastwave@Canberra were selling 4-room flats from $225,000. This is an increase in the lowest priced 4-room flats by 6.7 per cent ($240,000 divided by $225,000). Please explain 16.1 % price differential? If so, shouldn’t prices have fallen by about 9.4 per cent, instead of having increased by 6.7 per cent?
