Sell & buy timeline planning
Need to sell before you buy?
Unexpected ABSD can derail your plan.
- Selling before buying — Time your sale so you are not counted as owning two properties when you exercise the new launch OTP.
- Holding a property — Owning one property already changes the ABSD rate and the cash/CPF you need.
- Unexpected liability — Exercise dates and ownership counts can shift. Verify your status before committing.
