I moved from HK to SG 12 years ago for work. 1st year
rented a 4-room HDB flat. From 2nd year shared a private flat
with two flatmates. More comfortable and cut down cost.
US$2,200 (around S$3,000) should be enough to cover basic
expenses.
Accommodation: You can rent an HDB flat alone or share a condo
(budget S$1,200 - 1,500). Utility (electricity and water)
is incredibly high here (budget S$100 -150)
Healthcare: If not covered by your company, can go to a
Polyclinic (similar to government clinic in HK). Private
clinics charge quite low (~S$12 for consultation and up to ~S$20
including medicine).
Food: Cheaper than HK, if you don't mind eating in hawker
centres or food courts. Restaurant prices are comparable to
HK. Cooking ingredients here are higher because HK is
lucky to have fresh imports from China. (budget S$500)
Lifestyle: I missed the buzz and nightlife in HK. But
air is cleaner. Life is less stress. Much shorter working
hours because people are more family-conscious. People are friendly
to foreigners.
Transportation: Need to wait very long for buses and trains but
very safe and cheaper than HK. Taxi is affordable, just avoid peak
hours and from CBD. Car is considered a luxurious item
here.
