What Is a Sub-Sale?
A sub-sale is the sale of a property by the original purchaser before the project receives its Temporary Occupation Permit (TOP). In the private residential market, sub-sales of private condominiums are permitted — the original buyer can resell their unit at any time after signing the Sale and Purchase Agreement (SPA), subject to paying Seller's Stamp Duty (SSD) if the holding period is less than 3 years.
Executive Condominiums operate under different rules. EC sub-sales are prohibited.
EC Sub-Sale Prohibition: The Rule
Under the Housing Developers (Control and Licensing) Act and the Housing Developers Rules, EC purchasers are prohibited from selling their unit before the project receives its Certificate of Statutory Completion (CSC) — and in practice, HDB's conditions go further, linking the resale restriction to the Minimum Occupation Period (MOP).
The EC resale timeline works as follows:
- Before TOP: No sale permitted. The unit cannot be sub-sold to any buyer. This is an absolute prohibition, not subject to any exception or waiver.
- After TOP, before 5-year MOP is satisfied: The EC can be sold — but only to Singapore Citizens or Singapore Permanent Residents. It cannot be sold to foreigners or companies during this period. This restriction applies regardless of the buyer's eligibility to purchase HDB or the price of the EC.
- After 5-year MOP (10 years from TOP): The EC is fully privatised. It can be sold to anyone, including foreigners and companies, at market price, with no HDB eligibility requirements on the buyer.
What Happens If an EC Buyer Cannot Continue Payments?
If an EC buyer faces financial difficulty after signing the SPA but before TOP, their options are limited:
- Negotiate with the developer: In extreme circumstances, some developers may agree to rescind the SPA by mutual consent. The buyer typically forfeits the booking fee (1% of purchase price) and potentially additional amounts depending on the SPA terms. This is not a statutory right — it depends on the developer's willingness to agree.
- Default on the SPA: If the buyer fails to complete the purchase, the developer can forfeit the deposit paid and sue for damages. For a S$1.2M EC where 20% has been paid (S$240,000), the buyer risks losing the entire deposit paid and facing an additional claim for any loss on resale by the developer.
- Obtain a bridging loan: If the difficulty is temporary cash flow, a bridging loan may allow the buyer to complete the purchase and deal with the situation after TOP when resale becomes possible.
After TOP: Resale to SC and SPR Only (During MOP)
Once the EC receives its TOP, the 5-year MOP clock starts. During this period, the EC unit can be sold — but only to Singapore Citizens or Singapore Permanent Residents who meet HDB's EC resale eligibility criteria.
Key eligibility conditions for EC resale buyers (during MOP period):
- The buyer must be an SC or SPR forming a family nucleus or applying under the Joint Singles Scheme (for 2-room units, where applicable).
- The buyer must not currently own any other HDB flat or EC (or must have disposed of it before the new purchase).
- The buyer is not subject to any HDB eligibility restrictions that would prevent purchase (e.g., 30-month wait-out period from selling a private property, if applicable).
There is no income ceiling for resale EC purchases during the MOP period — the S$16,000 income ceiling applies only to new launch EC purchases directly from the developer.
After Full Privatisation: 10 Years from TOP
An EC is fully privatised 10 years after TOP. At that point, it is treated in the same way as any private condominium:
- It can be sold to anyone, including foreigners and companies.
- The buyer is subject to ABSD at their applicable rate and BSD at residential rates.
- There are no HDB eligibility requirements on the buyer.
- CPF usage rules for private property apply to the buyer (not HDB flat CPF rules).
SSD on EC Resale During MOP Period
EC units are classified as private residential property for Seller's Stamp Duty purposes once they receive their TOP. If an EC owner sells within 3 years of the date of purchase (the SPA signing date), SSD applies at:
- 12% if sold in year 1 (within 1 year of purchase)
- 8% if sold in year 2 (more than 1, up to 2 years after purchase)
- 4% if sold in year 3 (more than 2, up to 3 years after purchase)
- 0% if sold more than 3 years after the date of purchase
Since the MOP for ECs is 5 years from TOP, and the TOP typically occurs 3–4 years after SPA signing, most EC sellers who sell immediately after MOP have already held the property for 8–9 years from SPA date — well beyond the 3-year SSD window. SSD is generally not an issue for EC sellers who comply with the MOP before selling.
Frequently Asked Questions
Q: Can I sell my EC before TOP if I need to move overseas?
A: No. EC sub-sales before TOP are prohibited under the Housing Developers Rules. There is no exception for relocation, financial hardship, or changed circumstances. If you cannot continue the purchase, your only option is to negotiate a mutual rescission with the developer (at a cost) or default on the SPA and face forfeiture of your deposit.
Q: Can a foreigner buy my EC after TOP?
A: Not until the EC has been fully privatised, which occurs 10 years after TOP. During the first 5 years after TOP (the MOP period), EC resale is restricted to Singapore Citizens and Singapore Permanent Residents only. After full privatisation at 10 years, the EC can be sold to anyone, including foreigners.
Q: Is there an income ceiling for buying an EC on the resale market?
A: No. The S$16,000 household income ceiling applies only to new launch EC purchases directly from the developer. There is no income ceiling for resale EC purchases from owners in the open market, whether during or after the MOP period.
Q: Does SSD apply when I sell my EC after MOP?
A: Generally no. SSD applies for 3 years from the purchase date (SPA signing). Since most ECs reach MOP (5 years from TOP) approximately 8–9 years after SPA signing, the 3-year SSD window has long passed by the time the MOP is satisfied. Check your specific SPA date to confirm.
Q: What is the difference between EC MOP and HDB MOP?
A: Both are 5-year minimum occupation periods, but they operate differently after MOP. HDB flats after MOP can be sold to eligible buyers (SC, SPR, or SC with non-citizen spouse under certain schemes) but retain HDB classification. ECs after MOP (but before 10 years from TOP) can only be sold to SC and SPR. After 10 years from TOP, the EC is fully privatised and can be sold to anyone like a private condo.
