Actually the SG mkt is weak too. First, you must consider SG has 5.5m population, compared to 3m for the entire Johor State. Secondly, SG developers are not doing soft launches by choice, but rather to avoid the bad media publicity of poor sales, should the mega-launch fail. In the past year, have you ever heard of a mega launch in SG, in contrast to 2 years ago when grand launches were the norm?
Third, using the example of Frasers, they are not making much money, if at all, at 1.3k psf but they are choosing to do so anyway because they know the market cant support 1.4k psf. Lastly, the loss making transactions are starting to tally up, esp at SG CCR, but so far, there has been no significant news of loss making transactions in Johor yet.
With the above factors in mind, I wouldn't overly run down JB while championing SG. I would be careful to invest in either properties too, given the current sentiments.
