Sub-sale activity surged from 198 transactions in 2020 to 1,428 in 2024, with many owners enjoying substantial gains. But since SSD rules tightened in 2025, the profit math has changed significantly — and timing now matters more than ever.
Imagine you bought a new-launch condo two or three years ago. The building isn't quite done yet, but prices have climbed. Do you cash out now, or hold on and wait for the unit to complete? This question has been one of the most talked-about topics in Singapore property over the past few years — sub-sale profits hit record averages in 2024. But since SSD rules tightened in 2025, sellers now need to be far more precise about timing, holding costs, and exit strategy before deciding.
Note that a sub-sale can technically occur any time before CSC, including after TOP — the terms aren't strictly interchangeable, but in everyday conversation "selling before TOP" is the phrase most commonly used.
Covid-19 created a strange dynamic in Singapore real estate. Construction projects across the country were delayed by months or even years, while pent-up demand for homes shot up after 2020, causing private property prices to rise rapidly. Buyers who purchased new launches between 2019 and 2021 saw their units increase in value much faster than usual — gains that would normally take many years to materialise.
At the same time, many completed-unit owners became reluctant to sell, because finding a replacement home was expensive — selling high also meant buying high. This tightened resale supply and nudged buyers toward the sub-sale market instead. As a result, sub-sale activity rose from 198 transactions in 2020 to 1,428 transactions in 2024, according to URA statistics. Numerous reports suggested a large majority of sub-sales were profitable in recent years — at least before factoring in SSD.
With so many people making quick profits from sub-sales, the government tightened Seller's Stamp Duty (SSD) rules in July 2025. The intent was to keep the property market stable in the long run — but the practical effect for sub-sale investors is a meaningfully longer holding period required to avoid SSD entirely, and significantly steeper duty if you sell within that window.

This is the critical detail every buyer of a recent new launch needs to internalise: if you purchased on or after 4 July 2025, you are now subject to a 4-year holding period, not 3 — and the Year 1 rate has jumped from 12% to 16%. On a unit with a $250,000 profit margin, selling within the first year under the new regime means $40,000 in SSD alone, before any other transaction costs. The same sale under the old 3-year regime would have cost $30,000 in SSD. The gap widens further the earlier you sell, and the new 4th-year tier means sellers now need to hold a full year longer than before to reach SSD-free status.
The core trade-off: Selling before TOP optimises for certainty and liquidity — you lock in a known profit now. Waiting optimises for total return — a larger buyer pool, potential rental income, and SSD-free proceeds, at the cost of tying up capital longer and accepting market risk during the wait.
There's no universal answer — it depends on your investment profile and what you need the capital for. Investors prioritising liquidity and certainty, who have another opportunity ready to deploy capital into, or who are uncomfortable holding through market uncertainty, may still prefer a sub-sale even with the SSD bite — provided the after-SSD profit still justifies the exit. Long-term investors who don't need the capital immediately, and who can absorb the holding period, generally benefit from waiting through TOP and ideally past the SSD-free threshold.
The calculation isn't just about the headline profit margin — it's about the after-SSD, after-cost profit margin, compared against what that capital could earn if redeployed elsewhere during the same period. A sub-sale that nets $150,000 after SSD today may outperform waiting two more years for a theoretically larger but uncertain gain, particularly if you have a clear, high-conviction use for the capital now.
If you bought a new launch in the past two to three years and are weighing a sub-sale, the first step is running the actual numbers — not the headline profit, but the profit after SSD at your specific holding period, compared against the realistic upside of waiting. The tightened SSD rules mean this calculation is far less forgiving of guesswork than it was during the 2024 wave, when almost any exit looked profitable.
The sub-sale conversations I have with clients today are noticeably more numbers-driven than they were two years ago — and that's a good thing. During the 2024 wave, a lot of sub-sale decisions were made on momentum rather than math, because almost any exit was profitable regardless of timing. That's no longer the case.
Before deciding whether to sub-sell, I'd want to see the actual after-SSD profit at your current holding period, compared against the after-SSD profit if you wait another 6, 12, or 18 months. Sometimes the difference is small enough that locking in certainty now makes sense. Sometimes waiting just past the next SSD tier changes the math meaningfully. This is exactly the kind of calculation worth doing properly before listing, not after.
If you're sitting on a pre-TOP unit and weighing your options, happy to run the numbers with you against the current SSD schedule and your specific purchase date.
