A subsale is the purchase of a private unit from an owner who bought it from a developer but has not yet received the legal title, so the new buyer takes over a contract that is still running. A resale is the purchase of a completed home from an owner who already holds the title. The practical differences lie in payment timing, the number of parties involved, stamp duty exposure for the seller and the date on which the buyer can move in.
TL;DR
- A subsale transfers an uncompleted developer purchase to a new buyer before the Certificate of Statutory Completion is issued; a resale involves a completed unit, or an HDB flat, with a straightforward transfer of title.
- In a subsale the buyer inherits the progressive payment schedule, so cash and loan disbursements follow construction stages instead of a single lump sum on completion.
- Buyer's Stamp Duty and Additional Buyer's Stamp Duty apply in both cases; Seller's Stamp Duty can affect the subsale seller, and the holding period was extended to four years for purchases on or after 4 July 2025.
- HDB flats are resale only, and the Minimum Occupation Period keeps them outside the revised Seller's Stamp Duty rules.
- The choice usually turns on timing, cash flow, the availability of a particular stack or layout, and how the price compares with recent transactions.

What subsale and resale mean in Singapore
The Urban Redevelopment Authority (URA) defines a sub-sale as the sale of a unit by a person who signed an agreement to buy it from a developer (or from a later purchaser) before the Certificate of Statutory Completion and the subsidiary strata titles have been issued for all units in the development, as summarised in a media analysis. In plain terms, the building may be at the foundation stage, under construction or newly topped out, but the legal title has not yet been fully issued.
A resale, by contrast, is the sale of a unit that is complete and titled. It covers private condominiums and landed homes sold by their existing owners, as well as HDB flats sold on the open market. Where the term is used loosely, "resale" can also describe a subsale in the sense of a second-hand sale from the first buyer, which is one reason the two terms are confused. For the purposes of this comparison, the dividing line is the issuance of the Certificate of Statutory Completion.
The timeline of a typical private development makes the distinction clearer:
- Launch: the developer sells units directly (a new sale).
- Construction: the first buyer pays in stages, and may sell the contract on to someone else (a subsale).
- Temporary Occupation Permit (TOP): the unit is habitable and vacant possession is delivered.
- Certificate of Statutory Completion: typically issued within about 12 months after TOP, according to one industry timing guide. From here, sales are resales.
How the subsale process works
In a subsale, the original buyer transfers their rights and obligations under the Sale and Purchase Agreement (S&P) to the new buyer, who inherits the remainder of the original contract, including the outstanding progressive payments due to the developer, according to a 2026 subsale guide. The window opens once the first owner has signed the S&P and runs up to the point when the title is issued.
The developer is not a bystander. At the new buyer's request, made through their lawyers, the developer is obliged to enter a fresh S&P with the new buyer on the same price and terms that applied to the original buyer, as one conveyancing explainer describes it. This extra step is one reason a subsale tends to take slightly longer than a resale.
Three parties are therefore involved: the original buyer (the seller), the new buyer and the developer. The seller receives the profit on the deal, less taxes and legal fees, and the amounts already paid to the developer are credited back to them, per the same explainer.
How the resale process works
A private resale follows the familiar Option to Purchase and exercise sequence with a seller who owns the unit outright (or with a bank loan to discharge). The buyer pays the balance on completion, funded by cash, CPF where permitted and a bank loan. There is no developer to re-paper the contract and no remaining progressive payment schedule.
HDB resale carries its own administrative steps. According to a 2026 conveyancing overview, HDB will accept a complete resale application within 28 working days of receiving it, and the outcome of the Request for Value remains valid for three months. The buyer typically needs the HDB Flat Eligibility (HFE) letter before the seller grants the Option to Purchase, and confirms the financing mode on HDB's portal during the option period. For a closer look at how valuations feed into this stage, see our guide to HDB valuation before completion.
Side-by-side comparison
| Aspect | Subsale (private, uncompleted) | Resale (private, completed) | Resale (HDB) |
|---|---|---|---|
| Seller | Original buyer from the developer | Titled owner | Titled HDB owner |
| Contract | Fresh S&P with the developer on the original terms | Option to Purchase, then sale agreement | Option to Purchase, HDB resale application |
| Payment | Inherited progressive payment schedule | Balance due on completion | Balance due on completion |
| Completion | Roughly 10 to 12 weeks from exercise, per one agency guide | Standard conveyancing period | Depends on HDB approval and the Request for Value |
| Occupation | After TOP | Often immediate, subject to the seller's vacating date | After completion |
| Seller's Stamp Duty | May apply to the seller | May apply to the seller | Generally not triggered because of the Minimum Occupation Period |
The completion estimate comes from a subsale buying guide, which puts it slightly above that of a typical resale because of the additional legal steps.
Payment schedule and financing
The largest practical difference is cash flow. In a subsale, the buyer does not pay the full price up front. According to the same guide, the buyer pays 5% before completion (1% at the option and 4% at exercise), then pays the remaining 20% of the price at sub-sale completion, after which the bank takes over the remaining payments following the progressive payment schedule until the project is complete.
The consequences for planning are as follows:
- Loan structure: the bank loan may need to be arranged around the remaining payment stages rather than one lump-sum disbursement, as the 2026 subsale guide notes.
- Equity versus developer payments: the buyer needs to separate what is paid to the seller for their equity from what continues to be paid to the developer.
- Regulatory limits: the Total Debt Servicing Ratio (TDSR) and, where relevant, the Mortgage Servicing Ratio (MSR) apply as they do for any other purchase.
- Timing of the Option: more time should be allowed for the Option to Purchase and the exercise period than for a plain resale.
In a resale, financing is more conventional: the loan is drawn at completion and repayments begin at once. A buyer can run a personalised budget check using the haio affordability tool before deciding which route fits the monthly commitments.
Stamp duties and taxes
Buyer's costs
Buyer's Stamp Duty (BSD) applies to subsales and resales alike. IRAS publishes the residential schedule, in force for acquisitions on or after 15 February 2023: 1% on the first S$180,000, 2% on the next S$180,000, 3% on the next S$640,000, 4% on the next S$500,000, 5% on the next S$1,500,000 and 6% on the remainder. The duty is based on the purchase price or market value, whichever is higher, which for a subsale is the subsale price or market value, according to the 2026 subsale guide.
Additional Buyer's Stamp Duty (ABSD) is applied in the same way as for any other purchase. One 2026 stamp duty guide lists the rates in force since 27 April 2023: Singapore Citizens pay 0% on a first home, 20% on a second and 30% on a third or subsequent home; Permanent Residents pay 5%, 30% and 35%; foreigners pay 60% on any residential purchase. Because rules in this area change, readers should confirm current rates with IRAS before committing. Our overview of cooling measures in Singapore in 2026 tracks what applies now, and the guide to avoiding a 20% ABSD hit compares HDB and condo ownership paths for buyers who already own property.
Seller's Stamp Duty
Seller's Stamp Duty (SSD) matters mainly for the subsale seller, because a subsale by definition occurs soon after the original purchase. According to the Monetary Authority of Singapore, for residential properties purchased on or after 4 July 2025, SSD is 16% in year one, 12% in year two, 8% in year three and 4% in year four. For properties purchased from 11 March 2017 to 3 July 2025, the schedule is 12%, 8% and 4% within three years. The same release notes that the revised SSD does not affect HDB owners because of the Minimum Occupation Period, and that the Government cited a significant increase in sub-sales of uncompleted units as a reason for the change.
For a buyer, the point is indirect but real: a seller facing SSD may price the unit to recover it, which feeds into the asking price. Our explainer on seller's stamp duty after the July 2025 changes sets out how the holding periods work in practice.
HDB resale fees
HDB resale involves its own fees. A 2026 conveyancing overview lists an Option Fee of S$1 to S$1,000, an Option Exercise Fee that brings the total deposit to no more than S$5,000, a Request for Value fee of S$150 and a Resale Application Administrative Fee of S$40 for 1- and 2-room flats or S$80 for 3-room and larger flats. Buyers who expect to use grants should review the HDB Grants 2026 guide before setting a budget.
Pricing, inspection and defects cover
Subsale pricing is negotiated between two private parties, so it can reflect market conditions rather than the developer's launch pricing, and units that sold out at launch, including popular layouts or stacks, may be available again, as a subsale timing guide observes. A buyer can therefore sometimes secure a preferred floor or facing that is no longer offered by the developer.
The other side of the comparison is that a completed resale unit can be viewed, measured and compared with transactions in the same building. A subsale buyer typically relies on show-flat references, plans and the stage of construction. Another 2026 viewpoint notes that, with subsale premiums where they are, a well-chosen completed resale unit nearby may offer better yield and immediate use at a comparable price per square foot.
Defects cover also differs by timing. A subsale buyer receives the same Defects Liability Period coverage as the original buyer under the developer's S&P, and the period runs from vacant possession (TOP) rather than from the original signing date, per the timing guide cited above. In a resale, the buyer inspects the finished unit before completion, and any remaining protections depend on what the seller can pass on.
Once keys are in hand, fit-out planning begins for either route; a condo kitchen renovation planning guide illustrates the sequence of design, fabrication and installation that a compact apartment kitchen involves, though local rules on renovation approvals in Singapore condominiums should be checked with the management corporation.
Which route suits which buyer
The choice is usually clearer when framed by the buyer's priorities.
- Staged cash flow and time to plan: a subsale defers most of the price until the bank begins disbursing, which suits buyers who do not need to move in soon.
- Immediate occupation or rental income: a completed resale can be lived in or tenanted soon after completion.
- A specific stack, layout or project: a subsale may be the only way to obtain a unit in a sold-out launch.
- Public housing: HDB flats follow the resale route (or BTO from HDB). The comparison in BTO vs resale and the data in HDB flat prices by town support that decision.
- Running costs: older completed condos carry maintenance fees that deserve a look, as covered in the condo maintenance checklist.
Our perspective
Subsale and resale are often discussed as if one were a bargain and the other a safe choice. The more useful question is whether the price paid matches what comparable units have actually transacted at, and whether the payment schedule fits the buyer's income and loan limits.
Subsale prices are agreed between private individuals, which makes the transaction record the most reliable reference. We built haio to bring Singapore residential transaction data together in one place, so that a buyer or an agent can see the price history of a development, check a valuation and compare it with the asking price before committing to an Option.
The same applies to affordability. A subsale changes when money leaves the buyer's account, and a resale changes when the loan begins. Running a personalised affordability check against the current mortgage rates before viewing is, in our view, a sensible first step on either route, because it keeps the discussion anchored in numbers rather than in launch-day sentiment.
HAIO
Checking the numbers with haio
Before signing an Option on either type of unit, the two figures that matter are the price relative to recent transactions and the monthly commitment. haio provides price history and transactions for individual developments, such as Emery Point or Dorset Mansions, along with the Property Analysis page for deeper market views. Premium valuation reports and Master Plan tools are part of haio+, priced at S$49 per month or S$499 per year.
FAQ
Is a subsale cheaper than buying directly from the developer?
Not necessarily. The subsale price is negotiated between two private parties, so it may be above or below the launch price, depending on market conditions and what the seller needs to recover. The buyer should compare the asking price with recent transactions in the same development.
Does Seller's Stamp Duty apply to a subsale?
It can apply to the seller if the sale falls within the holding period. For residential purchases on or after 4 July 2025 the holding period is four years, at 16%, 12%, 8% and 4%, according to MAS. The buyer does not pay it, though it can influence the price the seller asks.
Can an HDB flat be a subsale?
No. Subsale refers to uncompleted private developments, and HDB flats are sold through the resale process. The Minimum Occupation Period also means the revised SSD does not affect HDB owners, per the MAS release.
How long does a subsale take to complete?
One agency guide puts completion at about 10 to 12 weeks from the exercise date, slightly longer than a typical resale because the developer issues a new S&P. The exact timing depends on the lawyers, the developer and the loan arrangements.
Do TDSR and ABSD apply to subsales?
Yes. TDSR and MSR calculations apply as for any other purchase, and ABSD is applied in the same way, according to the 2026 subsale guide. Buyers should confirm the current rules with IRAS and their lender.
