My view is this.
a) If you are a PR of many years, and for all intents, your company will not be transferring you, that is, Singapore is your permanent home base, then you have a point in your favor.
b) If you are in an executive or managerial role, with the income sufficient to support an expensive landed
property, then assuming you meet a), you get another point.
c) If you happen to be working for a MNC that provides lots of local jobs, then you get another point.
d) If you have started and are operating a successful business that pays taxes and hires locals then you definitely get a point, maybe two.
On the other hand,
a) If you are only EP, forget about it.
b) If you are PR and your kids are not, forget about it.
c) If you have moved a bunch before Singapore, forget about it.
