I bought a 4 rm flat under BTO (HDB),and Completion Date of flat is 2nd Quarter 2012. Delivery Possession Date (DPD) is 30 April 2013. At the present we are staying in rental. Now the rental price is too high.So that i am thinking to buy resale flat without cancelation of BTO flat. ( is it possible to own 2 flats?) what I need to consider?
