my first post. Be nice

Family and I will be moving to Singapore. Have visited SG many times, so do know the areas a bit. What I am very uncertain about is the right level of housing allowance.
Will be working in SG in the Services Industry, Vice President Level, Approx 80 Staff for a multinational company.
Family of 4, Parents + 2 kids under 10.
Package covers all expat benefits (Housing, Car, Medical etc etc)
Can you give me any indications what a reasonable level of housing allowance should be?
Not asking for your individual numbers, but you may have some range by experience from talking to people.
Thanks so much. This would help me big time!
