**Legally, you can sell a new private launch at any time, even before construction finishes (via a "sub-sale"). However, you should generally hold it for 3 to 4 years to avoid paying Seller’s Stamp Duty (SSD) to IRAS.**
If you bought an **Executive Condominium (EC)** or **HDB BTO**, open-market selling is strictly prohibited until you complete the statutory **5-year or 10-year Minimum Occupation Period (MOP)** starting from the date of key collection.

### 1. Selling a Private New Launch: The Sub-Sale Route
When you sell a private condo before it obtains its Temporary Occupation Permit (TOP) and Legal Completion, the transaction is known as a **sub-sale**.
* **How it works:** You transfer your rights and contractual obligations under the developer's Sale and Purchase (S&P) Agreement to a new buyer with the developer's consent.
* **When you can execute:** As soon as you have formally signed and exercised the S&P Agreement, your unit can technically be marketed for sub-sale.

### 2. Seller's Stamp Duty (SSD) Holding Clock
The SSD clock starts ticking from the **date you exercised the Option to Purchase (OTP) / S&P Agreement**, **not** when construction finishes or keys are collected.
SSD is payable in **cash** within 14 days of executing the sale contract, calculated on the **higher of the selling price or market valuation**:
| Holding Period | Bought On/After 4 July 2025 | Bought 11 Mar 2017 – 3 Jul 2025 |
| --- | --- | --- |
| **Up to 1 year** | **16%** | **12%** |
| **More than 1 year to 2 years** | **12%** | **8%** |
| **More than 2 years to 3 years** | **8%** | **4%** |
| **More than 3 years to 4 years** | **4%** | **0% (No SSD)** |
| **Beyond 4 years** | **0% (No SSD)** | **0% (No SSD)** |
> **Typical Timeline Advantage:** Because standard new launch condominiums require roughly **3 to 4 years to reach TOP**, holding until key collection often allows you to cross the SSD holding threshold naturally, letting you exit with **0% SSD**.

### 3. Key Financial Checks Before Doing a Sub-Sale
1. **CPF Accrued Interest:** Any CPF Ordinary Account funds utilized toward progressive stage payments and Buyer's Stamp Duty must be refunded back to your CPF account, along with 2.5% accrued annual interest.
2. **Buyer Pool Financing Restrictions:** Sub-sale buyers must adhere to standard progressive payment drawdowns and may face tighter financing approval timelines compared to direct developer units.
3. **Developer Administrative Fees:** Developers typically charge an administrative legal assignment fee (usually around S$500 to S$1,000 + GST) to endorse a sub-sale transfer.
