i guess the first concern is your health ! you have to travel here and there EVERYDAY !
I've many colleagues from my ex company who are now relocated to Singapore....
Many have done so for the first few years, and a little after they move into Singapore. The convenience of commuting in Sg is impeccable. However, there are those who decide to 'build their nest' in JB. Am unsure where, but aside from the daily crawl through the entry/exit points, They're very 'Happy' if you know what I mean.. lol.
I'm not familiar with JB, but my friends who live in JB permanently and work in Singapore live very close to the boarder. Guess they can afford that kind of rental la.
Updated Jan 2017, it is divide by 3.1 nowadays... recently you will need to factor in RM20 RC (Road Charge) if you travel daily in a SG registered car and S$6.4 RRC (Reciprocal Road Charge) if you travel daily in a Malaysian registered car.
Wonder if more and more people will opt for public transport, travel with motorcycle, or move into Singapore?
To avoid the causeway congestion. The Shuttle Tebrau train or the future HSR would be a good alternative to bus or motorcycle...
The cheapest option would be to walk across the causeway on foot. However, there was a case where a motorcyclist hit a pedestrian and he died a few days later unfortunately.
