Same here. I won't work in SG but live in JB cos the hassle of travel is too much. You want a bigger and cheaper home but you sacrifice convenience, time and energy. Time to me is money. Well, actually it's priceless.
Less time with family and loved ones cannot be earned back. Once it's gone, that's it. Feeling fatigue from the travel, jam and waking up early will affect my emotions. I don't want to be constantly looking at the watch to leave by a certain time or go home by when. You earn that cheap home but you have to sacrifice something that even money may not compensate it. But for some, it works for them, then by all means, do it. Yes, cost of homes in SG is getting ridiculously expensive.
To me, RTS can't happen even in 2019. 2018 was the projected date when the idea was thrown around several years ago. This year is 2016. 2019 is just 3 years away. Quite impossible to complete it. Till today, there are no firm plans as yet. I would say the completion time is.... unknown. I would bet my last dollar it will be after 2020. Maybe 2023? 2025? Or 2030? Maybe... never?
