About This Timeline

Fixed dates (exercise deadline, HDB acceptance deadline) come from HDB's own rules — 21 calendar days to exercise, and up to 28 working days (not calendar days) for HDB to process the resale application.
Estimated — HDB's own guide states about 8 weeks from acceptance to the Completion Appointment, covering safety inspection, endorsement and payment, HDB approval, and final inspection along the way.
Context — registering intent to sell (at least 7 days before granting the OTP) and the marketing period happen before this timeline starts, so they're shown for context without specific dates.
Total duration is typically 16–18 weeks from OTP grant to completion, excluding the marketing period — working days exclude weekends but not public holidays, so treat dates near a holiday with some buffer.
