UP FOR grabs: a two-room flat in Sembawang that costs just $10,000, with housing grants. With the Housing Board's latest Build-To-Order flat launch, experts say this has set the lowest price for a flat in recent memory. The HDB yesterday launched 3,497 new flats in the non-mature towns of Sembawang, Sengkang and Yishun. The price of two-room flats at the EastLace@Canberra and EastCrown@Canberra projects starts from $10,000 with housing grants, and $70,000 without grants. Only one flat boasts of this price, but others can be had for a few hundred dollars more.
