Every so often, a buyer tells me they found a condo unit that’s cheaper than the developer’s current price, still fairly new, but the agent called it a subsale. If you’re not sure what that means or how it differs from buying resale or straight from a new launch, you’re not alone. Subsale transactions sit in a grey zone that many buyers only encounter once, and the rules around financing, stamp duty and paperwork are different enough that it’s worth understanding before you make an offer.
What a Subsale Actually Is
A subsale happens when someone who bought a unit directly from the developer, usually under the progressive payment scheme, decides to sell it before the project receives its Certificate of Statutory Completion. This is different from a new launch purchase, where you buy directly from the developer, and different from a resale, where the seller has held a completed unit for years, sometimes decades.
In a subsale, the original buyer transfers their rights and obligations under the Sale and Purchase Agreement to you. The unit might still be under construction, recently completed, or fully finished but not yet subject to a Temporary Occupation Permit for very long. You inherit the remainder of the original contract, including any outstanding progressive payments due to the developer, rather than paying the full price upfront the way you would for a completed resale unit.
Why Sellers List a Unit for Subsale
The most common reason is timing around the Seller’s Stamp Duty holding period. If an owner needs to sell before the SSD period lapses, they may still proceed and simply account for the duty in their asking price or their own calculations. Others sell because their personal circumstances changed after booking the unit, whether that’s a job relocation, a change in family size, or a shift in financing needs.
Some subsale sellers are simply taking a view on the unit’s price movement relative to what they paid, factoring in what they’ve already funded through progressive payments plus any duties payable. It’s worth remembering that a subsale price reflects what a seller is willing to accept given their own cost base and holding period, not a signal about where the broader project or district is headed. I’d be careful about treating a subsale listing as evidence of anything beyond that individual seller’s situation.
Financing a Subsale: What Changes for You as the Buyer
Because a subsale unit is still under the developer’s progressive payment schedule if construction isn’t complete, your bank loan may need to be structured around the remaining payment stages rather than a single lump sum disbursement. Your mortgage banker will need the original Sale and Purchase Agreement, the payment schedule already fulfilled by the seller, and confirmation of what’s still outstanding to the developer.
You’ll also need to work out how much you’re paying the seller directly for their equity in the unit, sometimes called the subsale premium or option money differential, separate from what continues to be paid to the developer. This two-part structure catches some buyers off guard, so I always recommend getting your bank’s confirmation on the exact loan quantum and disbursement timeline before signing anything, ideally alongside a lawyer experienced in subsale transactions specifically, since not every conveyancing firm handles these regularly.
TDSR and MSR calculations still apply the same way they would for any other property purchase, so it’s worth running your numbers early, particularly if you’re juggling this alongside an existing HDB flat or another loan.
Stamp Duty and ABSD: Where Buyers Often Get Confused
As the buyer, you pay Buyer’s Stamp Duty based on the subsale purchase price or market value, whichever is higher, exactly as you would for a resale or new launch unit. If this isn’t your first residential property, Additional Buyer’s Stamp Duty applies in the same way it would for any other purchase, calculated on your profile at the point of exercising the option.
The seller, on the other hand, may be liable for Seller’s Stamp Duty if they’re within the holding period from their original purchase date, which for private residential property currently applies within the first three years. This is the seller’s obligation, not yours, but it often shapes the price they’re willing to accept, so understanding roughly where they stand on their own SSD timeline can help you gauge how much room there is to negotiate.
It’s also worth checking with your lawyer whether the developer requires a subsale administrative fee or written consent before the assignment can proceed, since some developments have specific clauses around this in the original Sale and Purchase Agreement.
Due Diligence Before You Commit
Ask for the full payment schedule and confirmation from the seller’s lawyer on exactly what has been paid to the developer so far, and what remains. Request the latest progress report on construction if the project isn’t completed yet, since delays can affect your own moving-in timeline and any bridging arrangements you might need.
If the unit is completed or near completion, arrange a viewing just as you would for any resale purchase, checking finishes, defects, and whether any snagging items from the original handover have been addressed. Because subsale transactions involve an extra layer of paperwork between developer, seller and buyer, I’d always build in a bit more time for your Option to Purchase and exercise period than you might for a straightforward resale deal, and confirm with your lawyer upfront what additional documents will be needed at each stage.
Subsale isn’t inherently more complicated or riskier than other purchase routes, but it does require a slightly different checklist. Buyers who go in understanding the structure tend to have a much smoother experience than those who assume it works exactly like a resale purchase.
