This Indonesian PR is not siao at all. I think he is very wise to pay for convenience and value (40th skyview). HDB and next door Condo are also 99 LH. Maybe just a couple with no kids or family. It is just perfect. Can see that the HDB is nicely done up. He don't have to pay extra for Condo maintenance. If he buy a metropolitan or Ascentia Sky, how much would he pay ? the extra million of dollar he could invest in business or stocks.
Highest psf was almost $5,000 for penthouse in Orchard Residence.
No HDB will not hit $1,000 psf. May be it does in 30 years time when SinKaPore has 13 million population when the PaPaya are no longer in charge, and you have to pay $15 for a bowl of noodle.
