healthcare here in singapore is costlier than city like bangkok and
KL, not so sure about HK's case. But I am sure you can quality
healthcare here. Also, your employer should be able to enroll you
in some group health insurance system. Also a visit to private
practitioner in neighbourhood centre should cost you no greater
than 25USD per visit.
Depending on where is your office, you may want to choose housing
nearer to your workplace. Singapore is a small island with 5M
population, the public transport is filling to the brim. The
traffic is very heavy during rush hours. Car ownership is very very
costly.
Living expense in low in singapore, food is cheap here.
US2200/month for monthly expensive put you in the upper class
living.
Singaporeans are voicing the displeasure of increasing number of
foreigners.
Remember to pay your taxes.
