I am not joking when I say this. Due to constant searches on housing in Japan, Facebook seems to be throwing its algo and think I am interested in a Japan property. So recently, they shared with me properties in Japan (Kawasaki City) going at USD$460,000 or about SGD$610,000 for properties of 50 mins travelling time to Tokyo Station and 50 mins to airport via train, of 1,100 square feet and a 2-3 years old house
If i were to extrapolate this to Singapore's context, it is akin to travelling from Woodlands or Sembawang area. While there is no data of 2-3 year old resale flat because Singapore law forbids the sale of such resale HDB, we do have data for 5 year old resale HDB flat of that floor area and in that area.
A search on HDB resale transaction based on these parameters tells 5 year old HDB resales are going at SGD$680,000-$820,000....
