About This Timeline

New ECs go through HDB eligibility processing before the developer can issue the Sale & Purchase Agreement — this step can genuinely drag beyond 3 weeks if HDB needs more supporting documents or there\u2019s an appeal case, so treat it as a planning estimate rather than a promise.
The remaining 15% follows one of two tracks: if approval and S&P issuance together take 9 weeks or less from booking, it\u2019s due by week 9 from booking. If it takes longer, it\u2019s due alongside exercising the S&P instead.
Progressive payments, TOP and CSC follow the same structure as a private new launch — EC and private condo purchases share the same Housing Developers Rules payment schedule.
