thanks for your help!
Just to clarify somethings, i am SPR working in SG now, i stay in SG during weekday and stay in nusajaya in weekend, still consider living in JB but just not use to the morning traffic at this moment, it take less than 10 mins to my office now, and the cost of of commuting dairy vs rental a room in Singapore is not much different for my case, i don't spend much during weekday except simple meal and i don't have much time to spend here, most of the time working, sleeping, watching downloaded movie and suffing, hence i don't ready bother about the high cost in Singapore, i spend most of my expenses during weekend in Malaysia and enjoy the space and freedom. Worst, most of the weekend i travel aroung malaysia and hardy stay in my house in JB. I do encourage and assist most of my friend Foreigner, SPR, Singaporean, Malaysian, FW or FT to buy house in Nusajaya, it wouldn't goes wrong if you buy within your mean.
