Well, you may not have to go the whole nine yards. Since it is a representative office, there are processes to get such a office set-up, for a lower cost, and obtain a residency / pass.

Less than S$ 1,000 = can be all completed. There are some rules for representative offices, and they will need to see the group turnover and such, and anyway, company secretaries can always advice the best course of action.

If you have no qualms in staying in residential apartments, like HDB, then the cost of living can be lower as well.

As I mentioned in another thread, you can live in Singapore, for a decent life, for less than 3,000 all-in-all, or pay more than 20,000 just for apartment rental alone. Depends on what you want to do ...

Cheers
