Not really... I think SG will still thrive in the next few decades. That's why the PM and his gang are constantly trying to inject new brilliant ideas on how to make SG stay vibrant and attractive. To do that, his message is that everyone has to "stay competitive". But along the way, things will become more and more expensive. It's an adjustment the citizens have to make. For eg, very soon, not everyone will need or be able to afford cars. But they have to improve a lot on the public transport system.
The fact that PM Lee has already mentioned about SG100 shows that he is serious about taking SG into the next lap. We have not reached a situation like HK or Tokyo yet.
As for Iskandar, it's a high risk investment for retail investors. If one doesn't believe the current news, data and facts presented by analysts and writers, then at least take it from the banks. As Xebay11 mentioned, one got to ask why the banks are extra careful in granting loans now. If Iskandar is such an easy-to-decide, low risk investment, wouldn't the banks want more borrowers?
For so many people who have rushed in to buy Iskandar properties in the last 2 years, imagine if they cannot finance their properties next time when they realize there are no rents, the condo facade is failing, every month they have to fork out high interest loans, pay maintenance fees, etc. The temptation then is to dump their properties which have become a liability. The banks can take back the properties but what are they going to do with them when there are no interested buyers? The banks could face a crisis.
Even before we go into the next 5 years, many of those who bought D'Inspire are already kicking themselves for buying a condo with lousy quality and designs. And part of their condo has already become some kind of cheap motel. This is not even the only condo with such bad outcome. Do we have confidence in other Iskandar condos?
To wait 20-30 years and see if an investment works out is a very long time and thus, I would say it's a very high risk. Some of us here may not even be alive! Sure, like fairy tale dreams, we can say Iskandar will thrive and become a second vibrant Singapore. Property prices will rise. But this is nothing more than speculation. It could also be the other way -- Iskandar becomes no different from the present JB. Your property value could remain very much stagnant. Or even if it appreciates in value, by how much? Can it beat the weak MYR currency risk, bank loan and inflation? You got to consider all these.
