Buying the next home before selling the flat means paying Additional Buyer’s Stamp Duty on the purchase, in full, upfront. For married couples, a remission mechanism can return that money after the flat is sold. This guide walks through how the mechanism works, what the parked money really costs, and the narrow band of situations where the route makes sense.
What are the rates at stake?
At the time of writing, under the IRAS schedule in effect since 27 April 2023, Singapore Citizens pay 0% ABSD on their first residential property, 20% on the second, and 30% on the third and beyond. Permanent Residents pay 5%, 30% and 35% on the same count, and foreigners pay 60%. The number that matters to a citizen upgrader buying before selling is the 20%: on the purchase date you still own the flat, so the condo is legally a second property.
By contrast, a sell-first upgrader who completes the sale before exercising the purchase owns zero residential properties at that moment and pays 0% ABSD. That difference is the entire financial case the buy-first route has to answer.
How does the remission mechanism actually work?
It is a refund, not an exemption, and the order of operations matters. The full ABSD is paid at the purchase. A married couple with at least one Singapore Citizen spouse may then apply for remission if the first home is sold within a qualifying window, and the money returns only when the sale qualifies. The exact length of that window, and the detailed conditions attached to it, must be verified against IRAS current rules before any commitment; this guide deliberately does not quote a figure that could be outdated by the time a decision is made.
Three consequences follow. The cash must exist upfront. It is locked up until the flat is sold and the claim is processed. And the flat sale is now running against a deadline.
What does the upfront sum look like?
Illustrative figures at the 20% citizen second-property rate, on round purchase prices:
| Purchase price (illustrative) | ABSD at 20% |
|---|---|
| $1,500,000 | $300,000 |
| $1,800,000 | $360,000 |
| $2,000,000 | $400,000 |
| $2,500,000 | $500,000 |
These sums land on top of the downpayment and the ordinary buyer’s stamp duty, at the exact point in the journey when a household’s cash is already most stretched.
What does parking that sum really cost?
The refund, when it arrives, returns the principal. What it does not return is the months in between: the buffer that was unavailable for renovation or emergencies, the strain of carrying two properties at once, and the opportunity cost of a five-to-six-figure sum doing nothing. The families who travel this route calmly are the ones who priced the parking period itself, not just the eventual refund.
The forced-sale clock
The qualifying window converts your flat sale from a market-paced process into a countdown, and countdowns change behaviour. A seller with a deadline discounts sooner, negotiates from a weaker seat, and accepts offers a patient seller would decline. If flats like yours sell slowly, the clock is not a detail of this route; it is the main risk of it.
When can this route make sense?
In a narrow band, and the shape of that band is specific. The next home is genuinely scarce: a particular stack, size or project that rarely surfaces, where losing it means years of waiting rather than weeks of searching. The flat sits in a segment where comparable units sell briskly, so the qualifying window is roomy relative to reality. And the household can fund the ABSD and carry both properties without depending on the refund arriving on schedule. Where all three hold, paying upfront for certainty over the purchase is a coherent, priceable choice. Where even one is missing, the sell-first route usually deserves another look before anything is signed.
The honest caveats
The remission conditions carry more detail than any guide can hold: who is on the title, the couple’s citizenship mix, and requirements that shift with policy. Rates themselves have changed before and can change again. Every figure above is either the schedule at the time of writing or an explicitly illustrative round number, and none of it substitutes for verifying the current IRAS schedule, the qualifying window and the full conditions before committing to a purchase that depends on them.
