Standard schedule for homes bought before completion (Housing Developers Rules; URA Home Buyer’s Guide): 5% booking fee, the rest of the first 20% within 3 weeks of receiving the sale and purchase agreement (8 weeks from booking if the developer allows), stamp duty within 14 days of signing (IRAS), then each stage within 14 days of the developer’s notice. Dates after signing are estimates from the expected TOP; the developer’s notices fix them. CPF can pay the 15% and stamp duty (often reimbursed after paying in cash) and the monthly instalments (CPF Board).

The stack I would show a friend first.
Brochures stop short of the useful part: which stacks at The Collective At One Sophia are better value per square foot today, which facing is close to selling out, and which units come back after a cancelled booking. I keep that shortlist up to date.
