How the range is worked out
Rooms
Each room has a fictional rate for Refresh and Replace. Living rooms, bedrooms and utility rooms scale with your floor area; kitchens and bathrooms do not. Kitchens and bathrooms add a fixtures allowance.
GST and reserve
The selected works get 9% GST, then a reserve of 10% at the low end and 15% at the high end. Both ends are rounded outward to the nearest S$500.
What stays outside
Wiring and pipes you are not sure about, structural review, concealed defects, appliances and management deposits never join the total. The planner lists them beside it instead.
