Selling your condo before TOP? Here's what you should know about sub-sale and SSD

Seller’s Stamp Duty was introduced more than a decade ago in 2010 in a bid to curb speculation and disincentivize house flipping in the real estate market. Since then, sub-sales of condos have been steadily declining, with numbers spiking again in 2021.


Looking at the numbers over the last decade (since 2012), the top 3 districts with the most sub-sales are:

• District 19 (Hougang/ Punggol/ Sengkang): 986 sub-sales
• District 18 (Pasir Ris/ Simei/ Tampines): 653 sub-sales
• District 15 (East Coast): 480 sub-sales

The areas with the lowest number of sub-sales are:

• District 6 (City Hall/ Clarke Quay): 0 sub-sales
• District 25 (Admiralty/ Woodlands): 27 sub-sales
• District 7 (Beach Road/ Bugis/ Rochor): 42 sub-sales

What is a sub-sale?

Sub-sales occur when a property is bought from a developer and sold to another buyer before the development is completed and receives the Certificate of Statutory Completion (CSC). While the terms CSC and Temporary Occupation Permit (TOP) are often used interchangeably amongst property owners, they mean different things.

A development can only be open for residential living after obtaining a TOP. Remaining works such as completing the swimming pool or other amenities can be carried out in the meantime.

On the other hand, the CSC has more requirements to certify that the development is completely done.

The legal completion dates for TOP and CSC may be completely different. Just because the condo has residents already living there doesn’t mean it has obtained its CSC.

According to the Building and Construction Authority (BCA) guidelines, the general period given to developers to obtain the CSC is one year after obtaining TOP.

Seller’s stamp duty (SSD)

Bought a private property last year and want to flip it this year for a fat profit? Not so fast. Owners looking for a sub-sale opportunity need to factor in seller’s stamp duty (SSD), which will take a hefty bite out of your sale proceeds.

Paying SSD is compulsory if you decide to sell your residential property within three years of purchase. The rate is based on the property’s market valuation or selling price (whichever is higher).

• Sell within one year of purchase – 12 per cent SSD
• Sell within two years of purchase – 8 per cent SSD
• Sell within three years of purchase – 4 per cent SSD

Example: You purchase a condo for $2 million. You decide to sell it next year. This means you have to pay a 12 per cent SSD of $240,000. Not factoring in the myriad of other legal fees, you need to sell your unit at S$2.24 million or more just to break even.

You should only sell your unit four years after signing the sales and purchase agreement (S&PA) to avoid paying SSD.

Want to sub-sell your unit?

If you’ve already signed the S&PA and the developer has not yet conveyed the legal title of the unit to you, you’ll need to inform the developer of the sub-sale. This can be done through the agent in charge of your original sale.

The developer will then enter into a new S&PA agreement with the sub-purchaser, with the same terms and conditions you received when purchasing the unit.

Other cost considerations

You need to consider more than just SSD when selling a sub-sale.

Buyer’s stamp duty. You would’ve had to pay Buyer’s Stamp Duty (BSD) when you first purchased your unit.

Just like SSD, BSD is based on the higher of your property purchase price or market valuation.

Here are the current BSD rates:

Purchase price or market value of property BSD rates for residential properties
First $180,000 1 per cent
Next $180,000 2 per cent
Next $640,000 3 per cent
Remaining amount 4 per cent

On a $2 million property, here’s the BSD you need to pay:

Market value of property BSD rate Calculation Total
First $180,000 1 per cent 1 per cent x $180,000 $1,800
Next $180,000 2 per cent 2 per cent x $180,000 $3,600
Next $640,000 3 per cent 3 per cent x $640,000 $19,200
Remaining $1,000,000 4 per cent 4 per cent x $1,000,000 $40,000
BSD Payable: $1,800 + $3,600 + $19,200 + $40,000 = $64,600

Agent fees. You pay zero agent commissions when you first purchase a new launch unit from the developer. However, if you choose to engage an agent to assist in your sub-sale, you need to pay your agent 2per cent of the selling price.

The commission will likely be co-shared between both your agent and the buyer’s agent.

Accrued interest. To ensure all Singaporeans have enough funds for retirement, the government requires that accrued interest be returned to your CPF Ordinary Account (OA) at 2.5 per cent per annum. This would be the amount of interest you would’ve earned if you didn’t use your CPF OA for your home down payment and to service your monthly home loans.

Let’s say you bought your condo at $2 million. Your loan-to-value (LTV) limit is 75 per cent, which means a downpayment of 25 per cent (5 per cent cash and 20 per cent from your OA).

Down payment amount taken from OA
$2 million x 20 per cent = $400,000

If you held your condo for two years before selling it via sub-sale, you will need to pay accrued interest.

Accrued interest
$400,000 x 2.5 per cent x two years = $20,000

Total amount to be returned to CPF
$400,000 + $20,000 = $420,000

This amount will go back into your OA, which you can then use for future property transactions.

If you allocate more cash towards your downpayment, you can pay lesser accrued interest.

Total cost considerations

Now that we’ve addressed all the cost concerns, let’s see how they add up on a $2 million property sold after two years.

BSD: $64,600
SSD (8 per cent): $160,000
Agent fees (2 per cent): $40,000
Accrued interest: $20,000
Total costs = $284,600

After totalling all costs, you need to sell your property at $2,284,600 just to break even.

Still wanting to sell your property before TOP? Here’s how you can save more

• Wait as long as possible to decrease or avoid paying SSD. After four years, there’s zero SSD payable.
• Use more cash instead of CPF OA when paying your downpayment to decrease accrued interest payable.
• Market the unit yourself to a direct buyer to save on agent fees (although we don’t recommend this, as the process for a sub-sale can get complicated and lengthy).

Why some choose to buy a sub-sale property

Compared to purchasing resale, buying a sub-sale means getting a brand new unit. Those looking for a shorter TOP period may choose to purchase a sub-sale and cut the waiting time.

Average price (S$) psf
Location 2015 2016 2017 2018 2019 2020 2021 2022
CCR $1,871 $2,008 $1,964 $2,176 $2,330 $2,203 $2,341 $2,436
RCR $1,388 $1,396 $1,469 $1,593 $1,716 $1,676 $1,800 $1,850
OCR $1,105 $1,131 $1,156 $1,188 $1,274 $1,296 $1,318 $1,352

The average price psf has been climbing year-on-year for condos island-wide, but is it climbing fast enough for you to turn a profit on your sub-sale?

As with all properties, resale prices depend heavily on location and what buyers are looking for at that point in time (proximity to schools, amenities, transport, connectivity etc.).

As long as you can find a willing buyer who can accept your price, it’ll be possible to break even or even make a profit.
