HDB resale flat sale typically takes 8–12 weeks from OTP signing to completion as of 2026. The timeline includes 21 days for HDB approval of the resale application, 21 days for the buyer's HFE letter (if not pre-obtained), and final completion 4–6 weeks later. Plus and Prime flats may add another 2–3 weeks due to additional eligibility checks.
Step-by-step HDB resale timeline

| 2 | OTP exercise (4% top-up to 5%) | Day 14–21 |

| 6 | HDB approval received | Day 42–49 |
| 8 | Final completion appointment | Day 56–84 |

The buyer's HFE letter must be valid at the time of OTP signing. If expired, the timeline extends by 3–4 weeks. Source: HDB resale process.

For upgraders: how this affects ABSD timeline
HDB upgraders relying on the 6-month ABSD refund window should:
- List HDB for sale BEFORE buying the new condo (or simultaneously)
- Pre-screen buyers to avoid fallthroughs
- Allow 8-12 weeks for sale completion
- Build in a 6-8 week buffer before the ABSD refund deadline
