Two things:

First one, which nobody mentioned specifically, but I think is a HUGE deal in this particular region: Singapore is the only country in 2000 miles radius where you can drink tap water anywhere without risking 'getting' something in return.

Second one, this you release once you move here from States/EU: you are paying 1/3 of taxes for the same income you had in your home. (yes, I know that US citizens are taxed from the worldwide income and I can quote you Publication 59.

And yes, I know that rent for 1br - where you can't swing a dead cat by the tail without hitting walls - is higher than mortgage for for 6br 3 floor McMansion back home. But still)
