In Singapore’s property market, the idea of buying an older condominium and waiting for an en bloc sale has always been attractive. The logic seems simple — enter early, wait for a collective sale, and walk away with a windfall.
And to be fair, there have been real success stories. Entire developments have been sold at prices significantly above market value, with owners making substantial profits.
But what many buyers don’t realise is this:
en bloc is not a strategy — it is a possibility.
Understanding the difference between the two is what separates a smart investment from a risky bet.
Understanding En Bloc: The Basics
An en bloc sale (collective sale) happens when at least 80% of owners in a development agree to sell the entire property to a developer. The developer then redevelops the land, usually into a new residential project.
Because developers are buying land at scale, they are often willing to pay a premium — especially for sites with strong redevelopment potential.
On paper, this sounds like an easy win.
In reality, the en bloc process is complex and time-consuming, often extending up to two years. It necessitates agreement from a significant majority of owners, and even with such agreement, the sale may still fall through.
The process involves multiple stages, including obtaining consent from owners, marketing the property, negotiating price, distribution and terms, and legal completion.
Some developments go through multiple en bloc attempts over many years — without success.
En bloc sales can be highly profitable for property owners. Because of this there are buyers eager to invest in older condos, anticipating a windfall when an en bloc sale occurs. However, it’s crucial to recognize that the profit margin may be lower for every subsequent buyer as the development ages, given that they purchased at potential en bloc prices.
The Real Appeal: Why Buyers Are Drawn In
The main attraction is obvious — the potential for higher-than-market windfall returns.
There is also a perception that older developments, especially freehold ones, are “sitting on land value” that will eventually be unlocked.
And in some cases, this is true.
But what often gets overlooked is how much you are paying to enter that opportunity.
The Biggest Misunderstanding: You May Already Be Paying for the En Bloc
One of the most important factors — and one that many buyers miss — is pricing.
Older condos with “en bloc potential” are rarely cheap. In fact, many are already priced with that future upside in mind.
This means you could be buying into the expectation of an en bloc, not just the property itself.
Imagine this:
An early owner bought the unit years ago at a much lower price.
You are buying today at a significantly higher price — partly because the market already believes an en bloc may happen.
If the en bloc goes through, the developer may pay a premium—but your actual profit could be much smaller.
Meanwhile, the early owners walk away with substantial gains.
This is why entry price matters far more than the en bloc story itself.
Simple: No sellers will sell you an enbloc potential condo without factoring the expected price. They are selling because they are tired of waiting; they’d rather take their share now and let you do the waiting.
What Actually Makes an En Bloc Likely?
Not all old condos are equal. Some have genuine redevelopment potential, while others are simply old.
Developers typically look at a few key factors:
- Whether the land can be intensified (higher plot ratio)
- The size of the site (larger sites are more attractive)
- Location — proximity to MRT, city fringe, or prime districts
- Redevelopment constraints — Zoning, height limits, and restrictions
- Leasehold considerations — Remaining lease for 99-year properties
- Competition from Government Land Sales (GLS) nearby
- Surrounding supply and upcoming projects pipeline
- Profit Margin — ultimately, the numbers must work.
Beyond these site-specific factors, market conditions also play a critical role.
The Government Land Sales (GLS) programme is one of the biggest competitors to en bloc. If a nearby GLS site is available at a reasonable price, developers may choose it over the complexity and uncertainty of a collective sale.
At the same time, supply in the surrounding area matters. If there are already multiple new launches nearby — or a large pipeline of upcoming projects — developers may hold back. Launching into an oversupplied market increases risk, slows sales, and puts pressure on pricing.
Even a strong en bloc site can struggle to attract interest if the surrounding market is already crowded.
At the end of the day, it comes down to a simple question:
Does the deal make financial sense for the developer?
If the answer is no, the en bloc will not happen — regardless of how “good” the site may appear.
Age alone does not create en bloc potential.
As a buyer, a useful approach is to think like a developer — and evaluate whether these factors actually support the potential before committing to an older unit.
The Hidden Cost of Waiting
Waiting for en bloc is not passive — it comes with real financial implications.
As developments age, maintenance costs tend to rise. It’s not just about repairs; in 2026, the Progressive Wage Model (PWM) and rising utility tariffs have pushed MCST fees to record highs. You are paying more just to keep the lights on.
At the same time, older condos face a “Rental Squeeze.” With a wave of modern projects hitting the market, tenants are increasingly selective. Why choose a dated layout when newer developments offer co-working pods and better newer facilities? This creates a “holding trap”: your rental income weakens while your ownership costs climb.
In simple terms, you could be paying to wait.
What makes this more challenging is the broader market reality. In today’s environment, there are simply too many ageing developments competing for a limited pool of developers. Not every project gets picked up, and some go through multiple en bloc attempts over many years without success.
As time passes, the development continues to age further. The condition declines, lease decay becomes more relevant for 99-year properties, and overall attractiveness to developers may weaken.
By the time real interest comes, the financial position may already be less favourable than expected.
The Reality of En Bloc Cycles
Another key factor many overlook is timing.
En bloc activity in Singapore is not constant — it moves in cycles.
There are periods where developers are aggressive and land demand is strong. And there are long stretches where activity is quiet, even for good sites.
This means you could be holding a property for many years with no movement at all.
Buying purely for en bloc without considering timing is like waiting for a bus without knowing if it’s even running.
The Risk Most People Don’t Talk About
There is also a downside that many buyers do not fully consider.
If 80% of owners agree to sell, the sale can proceed — even if you personally do not want to.
This means you may be forced to exit at a price you did not plan for.
If you entered the property at a high price, your profit could be limited — or in some cases, barely worthwhile — while earlier owners still benefit significantly.
The SSD Trap: If an en bloc happens too quickly after you buy, you could be hit by the Seller’s Stamp Duty (SSD). If the sale is finalized within the first three years of your ownership, the SSD (which can be as high as 12%) can swallow a massive portion of your “windfall.”
This is why en bloc is not just about upside. There is also exit risk.
Who Is This Strategy Actually Suitable For?
Buying an old condo for en bloc potential is not wrong — but it is not for everyone.
It tends to suit buyers who:
Have strong holding power and are not financially stretched
Are comfortable with uncertainty and long timelines
Understand that en bloc is a bonus, not a guarantee
Are buying at a price that makes sense even without en bloc
If your entire plan depends on a future collective sale, the risk becomes much higher.
The Right Way to Look at It
A more grounded approach is this:
Evaluate the property based on today’s fundamentals.
Does the price make sense relative to the market?
Is the rental reasonable?
Can you comfortably hold it long term?
If the answers are yes, then any future en bloc becomes an upside — not a dependency.
That is the safer way to approach this strategy.
Thorough Due Diligence — What You Should Really Be Looking At
Before considering an older condominium purely for its en bloc potential, it is important to go beyond surface-level assumptions and take a more structured approach.
Start by understanding the track record of en bloc attempts in the area. Some locations have seen multiple successful collective sales, while others have had repeated attempts that never materialised. This gives you a sense of how realistic the opportunity actually is.
Next, look at the land fundamentals of the development itself. Factors such as plot ratio, site size, and redevelopment restrictions will determine whether the site is attractive to developers in the first place. Without these, the chances of a successful en bloc are naturally lower.
It is also important to study nearby Government Land Sales (GLS) sites and recent land bids. These transactions provide a real benchmark of how developers are pricing land in the area. If recent GLS prices are already tight, it may be difficult for an en bloc deal to meet both owners’ expectations and developers’ required margins.
Beyond that, assess the supply and pipeline in the surrounding area. If there are multiple new launches nearby — or a large number of upcoming projects — developers may be less willing to commit to another site in the same location.
You should also evaluate the current rental and holding position of the property. If the unit cannot generate reasonable rental income, you need to be comfortable with the possibility of holding it for an extended period while incurring ongoing costs.
Finally, and most importantly, avoid relying on en bloc as the primary reason for your purchase. The property should still make sense based on today’s pricing and fundamentals.
Conclusion
Buying an old condominium for en bloc potential can be appealing, but it is not as straightforward as it seems.
While the upside of a successful collective sale can be significant, the reality is that en bloc is uncertain, timing-dependent, and heavily influenced by factors beyond your control — such as developer demand, Government Land Sales (GLS) supply, and overall market conditions.
The key is to approach this strategy with the right mindset.
A property should first make sense based on today’s fundamentals — price, rental, and holding ability. If it does, then any future en bloc becomes a bonus rather than a dependency.
However, if the decision is based purely on the expectation of an en bloc, the risks increase significantly.
In some cases, holding an older property can still work — especially if it generates stable rental income and you are financially comfortable holding it over the long term. This provides flexibility while waiting for opportunities that may or may not arise.
At the end of the day, success in this strategy is not about predicting an en bloc —
it is about managing the risks while staying grounded in fundamentals.
En bloc should never be the reason you buy — it should only be the upside if it happens.
