Re: Singapore Property Market Unsustainable
As far as market direction is concerned, I’ve been monitoring the situation since 1996 when I arrived on these shores… if you compare with other major global cities, Singapore property price growth has significantly lagged global peers, which implies that property prices have been kept artificially low (which is as expected with the cooling measures).
I know this can seem hard to believe considering how high the prices already are, but crazy high prices have been the norm, and will continue to be the norm. There would have to be a deep and severe crisis (beyond what we have seen in recent decades) to see any meaningful decline IMO.
Even if demand declines, the supply side (land scarcity and developer constraints) in Singapore will always underpin high prices.

Re: Singapore Property Market Unsustainable
SSD for x years only doesn’t seem like a big deal to me, as long as it eventually tapers off to zero. Does this really impact genuine home buyers much?

Re: Singapore Property Market Unsustainable
Totally agree, it's making the future generations being less able to afford. I don't see it as a good thing at all. This trend is very worrying.
A lot of HDB BTO owners sell with a good profit and buy new launches, and new launches are the ones making the prices so out of reach. When there's demand, developers can call their prices. Many sell out like hot cakes.
I don't think the additional 1 year of SSD is going to stop people from flipping. They could have implemented 5 years like HDB MOP.
