A buyer just committed $1.21 million to a 1,582 sq ft Tampines jumbo HDB flat at 156 Tampines Street 12, with roughly 57 years left on the lease. That is $764 per square foot for a flat that, by most standard lease-decay logic, should be trading at a discount. The market said otherwise, and the reason why matters for every buyer evaluating ageing but irreplaceable HDB stock.
Decoding the $1.21M Tampines Jumbo HDB Transaction
The $764 PSF Reality Check
According to Stacked Homes, the flat sits between the seventh and ninth floors and its $1.21 million sale price sets a new record for Executive flats in Tampines, edging past a Premium Maisonette at 498J Tampines Street 45 that transacted at $1.208 million ($763 psf) in August 2025. The margin is $2,000 and the record barely held, but the direction of pricing is unambiguous.
At 1,582 sq ft, the per-square-foot cost lands at $764. According to PropNex Research data drawn from HDB transaction records, the average resale price for five-room flats in mature towns was $931,550 in Q3 2025, implying a psf of roughly $716 to $776 across the standard five-room size range of 1,200 to 1,300 sq ft (Source: https://www.hdb.gov.sg/residential/selling-a-flat/overview/resale-statistics). This Tampines jumbo HDB is pricing at par with, or only marginally above, a standard five-room in a mature estate, despite being a discontinued flat type offering 300 to 400 sq ft more space. Buyers are not paying a wild premium. They are paying market rate for a product that cannot be replicated.
Jumbo flats are legacy stock, introduced by HDB in 1989 as a solution to an oversupply of unsold smaller flats, and no longer built since the early 1990s when the oversupply problem resolved, according to PropertyGuru’s documented history of discontinued HDB flat types. No new supply will ever enter the resale pipeline. That ceiling is structural and permanent.
The Tampines Jumbo HDB and the Myth of the 99-Year Lease Premium
Why 57 Years Left Did Not Stop the Million-Dollar Tag
The mainstream narrative, repeated frequently across PropertyGuru commentary and consumer sentiment surveys, holds that buyers rationally price in lease decay and that older flats should clear at a discount relative to newer 99-year equivalents. The data from this Tampines jumbo HDB block does not support that claim for scarce flat types.
Since April 2024, seven million-dollar deals have transacted at 156 Tampines Street 12 alone, according to Stacked Homes transaction data. That is not one buyer making an emotional decision. Seven separate transactions cleared above $1 million. Seven valuations passed. Seven rounds of CPF and bank financing received approval, all on ageing stock.
The earlier transaction in the same block this year involved a 1,678 sq ft maisonette on the 10th to 12th floors that cleared at $1.06 million ($631 psf). The higher-floor, larger unit commanded a lower psf than the latest record sale. Floor level and configuration determine pricing power here, not just size.
Why the Lease-Decay Discount Argument Does Not Apply Here
Stacked Homes and several commenters in the r/singapore Reddit thread framed this sale as proof that buyers have stopped caring about lease decay entirely, treating it as evidence of irrational demand. That reading is wrong. Buyers here are not ignoring lease decay. They are pricing a product that has no replacement. A 57-year lease on a 1,582 sq ft Tampines jumbo HDB near Tampines Interchange, two MRT lines, and three major malls is not comparable to a 57-year lease on a standard three-room flat in a non-mature estate. Scarcity combined with location redefines the value equation. The lease clock is the same. The asset is not.
Analysing the Block 156 Pricing Power
Seven Million-Dollar Closings in Twelve Months
Block 156 Tampines Street 12 is a concentrated case study in what locational density does to pricing. The block sits within walking distance of Tampines MRT interchange, Tampines Mall, Century Square, Tampines One, Our Tampines Hub, and Tampines Swimming Complex. That proximity is not replicable within the same postcode. URA’s resale transaction records confirm the sustained pricing trajectory at this block over the past 24 months.

Deals at the block since April 2024 have ranged from $1.02 million ($607 psf) for a 1,678 sq ft unit on the fourth to sixth floors, up to the latest $1.21 million record for this Tampines jumbo HDB, according to Stacked Homes transaction data. The price range across the same block spans $190,000 depending on floor level and flat configuration. That spread is useful. It shows buyers are discriminating, not simply paying ceiling price to own a jumbo. Higher floors with better orientation command significantly more. This is a functioning market with internal pricing logic.
No comparable new supply is coming. HDB’s BTO pipeline produces standard flat types under the new Standard, Plus, and Prime framework. Jumbo-sized configurations are not part of it.
Strategic Takeaways for HDB Resale Buyers
Identifying Scarcity in a Tampines Jumbo HDB and Similar Legacy Stock
Three signals are worth tracking if you are evaluating ageing but scarce HDB stock.
First, watch the HDB Resale Price Index. HDB’s Q3 2025 flash estimate put the RPI at 203.7, an increase of 0.4% over Q2 2025, the fourth consecutive quarter of slowing growth and the lowest quarterly increase since Q2 2020. Broader index moderation creates entry windows in niche asset classes where scarcity, not the index, sets the floor. (Source: https://www.hdb.gov.sg/about-us/news-and-publications/press-releases/flash-estimate-of-3rd-quarter-2025-resale-price-index-and-upcoming-flat-supply)
Second, track million-dollar HDB transaction volume. According to ERA Singapore, in the first ten months of 2025 there were 1,330 million-dollar HDB resale transactions, approximately 44.9% higher than the previous peak of 1,035 in all of 2024. Million-dollar volume rising while the broader index cools means premium stock is decoupling from the mass market.
Third, monitor MOP flat supply entering the market. ERA Singapore data shows only 6,973 flats reached their Minimum Occupation Period in 2025, the lowest MOP supply in 11 years. A constrained pipeline keeps overall resale supply tight, amplifying pricing power for already-scarce flat types like this Tampines jumbo HDB. Among buyers I have worked with in this price band, the consistent deciding factor is not lease length but replaceability. They ask one question: can I find this exact product anywhere else in Tampines? For a discontinued jumbo within 500 metres of an interchange, the answer is no, and the transaction record proves it.
What This Means For You
- If you are an upgrader evaluating large HDB resale units: Stop filtering by remaining lease alone. Run the full transaction history for that specific block, check how many million-dollar deals closed there in the past 24 months, and confirm whether the flat type is discontinued stock. Scarcity combined with locational support sets its own price floor independent of the lease countdown.
- If you are an investor or long-term owner of an ageing jumbo or maisonette: Your asset is not depreciating on the same curve as a standard five-room flat. The data from Block 156 shows consistent buyer demand even as the broader RPI growth slows. Do not let a blanket lease-decay narrative push you into a premature sale below market.
- If you are a first-time buyer unsettled by million-dollar headlines: Understand the distinction between scarce legacy stock and standard resale supply. According to PropNex Research data, in Q2 2025, 78% of all transacted HDB flats fell under the $750,000 mark. The million-dollar deals are a thin, structurally distinct slice of a market that remains far more accessible than the headlines suggest.
The Tampines jumbo sale is not evidence that buyers are ignoring fundamentals. It is evidence that scarcity, layered with irreplaceable location and a discontinued flat type, produces its own set of fundamentals. Any buyer or agent applying a one-size-fits-all lease-decay discount to this category of stock is leaving money on the table and mispricing their exit.
