Three ways to buy in Sentosa Cove. What you paid mattered far more than which one you used.

There were three ways to buy an apartment in Sentosa Cove. New from the developer, resale from an owner, or sub-sale, which meant buying from someone who had bought off-plan and was selling before the building was finished. The rest of the Sentosa Cove findings are on the Sentosa Cove guide.

Which one you used mattered far less than what you paid.

Buyers who paid less than $1,678 per square foot made money between 50% and 72% of the time, whichever route they used. Buyers who paid more made money between 5% and 9% of the time, whichever route they used.

What is in this note

• The line: how often resale sellers made money, and their median outcome, by how they had bought and by whether they paid less or more than $1,678 per square foot.
• The route that dominated the peak: how many apartments changed hands each year from 2004 to 2011 as new sales, sub-sales and resales.
• Where the money went: what flippers made between buying from the developer and selling before completion, and how sellers on each route did between 2007 and 2010.
• One apartment, four sellers: every recorded sale of one apartment at The Azure.
• The resale market crossed the same line: how resale buyers did, grouped by when they bought, and what they paid per square foot.

The line

$1,678 per square foot is the median of every Sentosa Cove apartment resale from 2012 to 2026, the years after the last new launch. The median in any single year ranged from $1,429 (2019) to $2,125 (2023).

Sorting every resold apartment by what its buyer originally paid:

Bought	Paid under $1,678		Paid $1,678 or more
	Made money	Median outcome	Made money	Median outcome
New from the developer	72.4%	+17.8%	4.9%	-34.1%
Resale from an owner	51.0%	+1.8%	9.3%	-15.4%
Sub-sale	50.0%	-0.7%	5.9%	-19.6%

• Paid under $1,678 psf
• Paid $1,678 or more

The routes differ much less from each other than the two price groups do. Above $1,678, every route made money between 4.9% and 9.3% of the time. Below it, every route made money between 50.0% and 72.4% of the time.

The gap between the best and worst route is 22 percentage points. The gap between paying under the line and over it is 42 to 68 points, depending on the route.

Median outcome here covers everyone in that group, winners and losers together, so it turns negative whenever fewer than half made money. That is why the sub-sale row reads -0.7% at a 50% win rate: half made money, half did not, and the middle seller landed just below even.

The route that dominated the peak

Sub-sales were a large part of the Sentosa Cove market in its launch years.

Year	New sale	Sub-sale	Resale	Sub-sale share
2006	391	101	0	20.5%
2007	68	176	13	68.5%
2008	26	34	9	49.3%
2009	11	101	19	77.1%
2010	45	33	44	27.0%
2011	12	1	37	2.0%

• New sale
• Sub-sale
• Resale

In 2007 and 2009, two thirds to three quarters of everything that changed hands in the enclave was someone selling a home they had bought off-plan and did not yet own outright.

After 2010 they stopped: one sub-sale in 2011, and none since.

Across the enclave's whole history, sub-sale is 465 of 2,150 apartment transactions, 21.6%.

Where the money went

Most people who bought a unit from the developer and sold it before completion made money.

A flip here means one unit bought from the developer and sold on before the building was finished. To measure what the seller made, both halves have to be in the record: the price they paid the developer, and the price they sold at. That holds for 242 of the 465 sub-sales. For 121, the developer sale was never lodged as a caveat, so there is nothing to compare against. The other 102 were sold by someone who had themselves bought by sub-sale, so they are not flips as defined here. Both groups are left out of this table.

Flips where both prices are on record	242
Median time held	606 days
Sold within a year	85
Made money	225, or 93%
Median gain	+28.1%

Set that beside the buyers on the other side of those same transactions, who made money 20% of the time.

Between 2007 and 2010, almost everyone who sold made money, whichever route they had bought through: 92.9% of developer buyers, 81.3% of sub-sale buyers, and all seven of the resale buyers who sold in that window. The median gains ran from 17.9% to 37.9%.

Each of those gains was paid by the next buyer, and the buyers who bought at the highest prices later found no one to buy from them at a higher price. Prices in the enclave have not risen enough since to give those buyers a gain.

One apartment, four sellers

The Azure, a single unit, every sale on record:

Year	Sale	Price	What that seller made
2005	New from the developer	$1,632,000
2005	Sub-sale	$2,058,000	+$426,000
2007	Sub-sale	$3,488,000	+$1,430,000
2007	Sub-sale	$3,850,000	+$362,000
2021	Resale	$2,500,000	-$1,350,000

Three sellers took a combined $2.2 million out in twenty-four months. The fourth held for fourteen years and sold $1,350,000 below what they paid.

The buyer in 2007 paid 2.4 times what the developer had sold it for two years earlier, and no later buyer paid as much.

This is one unit, chosen because it shows the pattern clearly. It is an illustration, not evidence: the tables above are the evidence.

The resale market crossed the same line

Resale buyers who paid more than $1,678 per square foot lost money too.

Resale buyers, grouped by when they bought:

Bought	Resales	Made money	Median outcome	What they paid
2007 to 2011	30	16.7%	-17.7%	$1,744
2012 to 2014	24	12.5%	-10.4%	$1,788
2015 to 2017	23	56.5%	+2.7%	$1,519
2018 to 2020	9	33.3%	-7.0%	$1,548
2021 onwards	8	75.0%	+7.4%	$1,559

The turn is at 2015, and the last column says why. The first two groups paid $1,744 and $1,788, above the line. From 2015 they paid $1,519 to $1,559, below it.

The change came from the price they paid. From 2015, resale buyers paid less than $1,678 per square foot, and more than half of those who bought in 2015 to 2017, and from 2021 onwards, made money.

The last two groups rest on nine and eight sales, so read them as direction rather than measurement.

What this tells you

Every route made money more often below $1,678 per square foot than above it. Buyers who paid less made money between 50.0% and 72.4% of the time, depending on the route. Buyers who paid $1,678 or more made money between 4.9% and 9.3% of the time.

Sub-sales were most of the market at its peak, two thirds to three quarters of apartment transactions in 2007 and 2009. Of the flips with both prices on record, 93% made money, with a median gain of 28.1% in under two years. Between 2007 and 2010 most sellers on every route made money: 92.9% of developer buyers, 81.3% of sub-sale buyers and all seven resale buyers who sold in those years. Sub-sale buyers who have sold since March 2020 made money 20% of the time.

Resale buyers who bought from 2007 to 2014 paid a median $1,744 to $1,788 per square foot, and most of them lost money. Those who bought from 2015 onwards paid $1,519 to $1,559. More than half of those who bought in 2015 to 2017 and from 2021 onwards made money, but only a third of those who bought in 2018 to 2020 did. The last two groups rest on nine and eight sales.

The price paid explains the outcome better than the route. Sub-sale buyers did worst because they paid the most and bought in the most expensive years.

Buyers could see at the time that resale prices were lower. $1,678 can only be calculated now, from the resales since 2012. But resale prices were public every year, and from 2007 they were below what developers were charging for new units.

Buyers who paid above $1,678 have stayed down for a long time. Those who bought above it in 2007 are still below their purchase price, and so are those who bought above it in 2013.

What this does not tell you

• Who was buying or selling. Caveat records carry prices and dates, not names. We cannot see whether a sub-sale seller was an individual, an investor, or a party connected to the developer. Nothing in the pattern of these sales suggests units were transferred in bulk to a related company and sold from there, but the records cannot rule it out either.
• What 121 of the sub-sale sellers made. For 121 of the 465 sub-sales, about a quarter, the developer sale that must have come first is not in the record, so there is no purchase price to compare against. They are excluded from the flip figures and counted everywhere else.
• What the line will be after 2026. $1,678 describes 2012 to 2026. Nothing here says the same number applies to a purchase made later.
• Anything about costs. All figures are gross of stamp duties, agent fees, legal costs and holding costs.

Method and data notes. Sale data to 4 August 2026.

Figures are transacted prices from URA caveat data for Sentosa Cove non-landed projects, excluding collective sales. Non-landed means condominiums and apartments; the enclave's landed homes are excluded throughout.

A resale pair matches a home to its own previous recorded sale on the unit record. The outcome is the second price divided by the first. Only pairs whose sale falls on or after 1 March 2020 are counted.

What the buyer paid is the price per square foot on the earlier of the two sales.

The line, $1,678 per square foot, is the median of every Sentosa Cove apartment resale from 2012 to 2026.

A flip is a unit whose developer purchase and subsequent sub-sale are both on record. Where the developer purchase is missing, the sub-sale is excluded from the flip figures but still counted everywhere else.

Medians are used rather than averages.

Three resale pairs in this population begin at Marina Collection prices from 2012 that a court has since examined. See the note in our project-level article. Their recorded losses may be larger than the losses those buyers took.
