I agree with bro radha, major supply of completed HDB for sale will not come in till probably 2017, if HDB resale price up just 8% per year, between now and 2017, it has potential to go up another 40% to breach the 1million magic mark ... that means all flats now selling at 650-700k will be close to 1m which will boost BTO prices to at least 600k even in Punggol, way beyond affordability of 1st timers
The valuation of HDB resale flat is creeping up at about 60k per year, so say starting point is 600k
2013 660k
2014 720k
2015 780k
2016 840k
2017 900k
2018 960k
So the question is WHEN
Ride at your own risk !!!
