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.

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

Buyers who paid less than $1,679 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.

Key takeaways

• Below $1,679 per square foot, every route made money at least half the time. Above it, no route managed one in ten. The line
• Sub-sale was not a fringe route. In 2007 and 2009 it was two thirds to three quarters of everything traded in the enclave. The route that dominated the peak
• The people who sold those sub-sales did very well: 93% made money, a median 28% in under two years. So did almost everyone else selling into 2007 to 2010. Where the money went
• One apartment at The Azure changed hands three times in two years, then sold fourteen years later for $1,350,000 less. One apartment, four sellers
• Resale buyers were not spared. They lost too, until 2015, when the resale market itself dropped below the line. The resale market crossed the same line

The line

$1,679 per square foot is the median of every Sentosa Cove apartment resale between 2012 and 2026, the years after the last new launch. It is where the market has settled and stayed.

Sorting every resold apartment by what its buyer originally paid:

Bought	Paid under $1,679		Paid $1,679 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 $1,679 psf
• Paid $1,679 or more

Read across the rows and the routes differ. Read down the columns and they do not. Every route above the line lands between 4.9% and 9.3%. Every route below it lands between 50.0% and 72.4%.

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-sale is easy to dismiss as a small corner of the market. In Sentosa Cove it was not.

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 traded in the enclave was someone selling a home they had bought off-plan and did not yet own outright.

Then it stops. 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%. It was a fifth of everything ever traded there and, for two years, it was the market.

Where the money went

For the people selling those sub-sales, it worked.

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 the other 121 the developer sale was never lodged as a caveat, so there is nothing to compare against and they 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%

Ninety-three percent profitable, a median 28% in under two years, on a home most of them never lived in because it was not finished.

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

And it was not a flipper's advantage. Between 2007 and 2010, almost everyone who sold made money whatever 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%.

That is what a rising market does. Every one of those gains came from a buyer, and the chain of profitable exits ran until it reached someone who had nobody to sell to at a higher price.

The value did not disappear in Sentosa Cove. It moved, from the people who bought late to the people who bought early. What the enclave never did was grow enough to cover both.

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. Everything that happened afterwards was the market declining to agree.

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

Buying from an owner rather than a developer did not protect anyone either. It just took longer to matter.

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%	$1,789
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%	$1,560

The turn is at 2015, and the last column says why. The first two groups paid $1,744 and $1,789, above the line. From 2015 they paid $1,519 to $1,560, below it.

Nothing about those buyers changed. The market they were buying in dropped below the level it would sustain, and the people who bought after that mostly did fine.

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

What this means

The route is a description, not an explanation. Sub-sale buyers did worst because they paid the most and bought in the most expensive years, not because a sub-sale is a worse kind of purchase.

One number did the work, and it was available. $1,679 is a figure you can only calculate now, with fifteen years of hindsight. But the resale market was publishing a version of it every year, and from 2007 onwards it was consistently below what buyers were paying.

And a flat market punishes everyone who overpays, for a long time. Buyers above the line in 2007 are still down. So are buyers above it in 2013. The enclave has not risen enough to rescue either.

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 a quarter of them 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 is today. $1,679 describes 2012 to 2026. Nothing here says the same number applies to a purchase made now.
• Anything about costs. All figures are gross of stamp duties, agent fees, legal costs and holding costs.

Method

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, $1,679 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.
