Don't make blatant assumptions. I have lived in Singapore for so long of course I have seen them all. How big is Singapore?
It's similar to the case when someone says "You got to be careful when you walk around JB. You could be robbed and killed." Then, somehow, someone else will argue: "You think Singapore is safe? There are also crimes like rape and murder". That is obviously a faulty argument. No one says Singapore has 0% crime. But it's definitely a lot safer in Singapore. We are comparing cases IN GENERAL.
So I did not say there are totally no run down condos in Singapore that are less than 10 years old. I meant condos in JB IN GENERAL are in a worse off state than those in Singapore. And there are more of them in JB than Singapore. This is indisputable.
Just go and look around even at the recently completed ones in JB. Owners were given bad quality workmanship and cheap materials even a mass market condo in Singapore more than 5 years old will look better. That sort of quality is not acceptable at all in Singapore.
Actually there are a lot of new condos or mixed development residence in JB which have good quality.
If you take a look on other forum like sky******city,
you will know.
