HDB Depreciation Curve: Why Some Flats Hold Value Better Than Others
HDB depreciation isn’t really about a flat’s age — it’s about how the next buyer will value what’s left.
A shrinking lease is one input; location, size, layout, competing supply and next-owner confidence are the others.
This guide is the valuation lens on those factors, the real cash math behind a “gain,” and Cash Over Valuation — not the lease mechanics themselves.
For the age-95 CPF rule, loan tenure limits, and what happens at lease expiry, see the companion piece: HDB Lease Decay: What a Shrinking Lease Does to Your Flat’s Value, CPF and Loan.
This page stays on one question: what determines what buyers will actually pay.

Why a higher selling price doesn't always mean more cash
Many owners equate a higher sale price with profit.
But sale proceeds are used to settle two things first — the outstanding housing loan, then the CPF used (plus accrued interest).
Only what’s left after that is cash in hand. A real paper gain can still land at zero cash.
Here’s how that plays out on real numbers.
A homeowner bought an HDB flat 10 years ago for S$520,000, using S$150,000 CPF and a S$370,000 HDB loan over 30 years, with instalments of about S$1,481/month paid fully via CPF.
Ten years on, the flat sells for S$660,000 — a S$140,000 paper gain on the surface.
A higher selling price does not automatically become cash in hand. The outstanding housing loan is settled first, followed by the CPF refund that applies to the sale. This illustration shows why a S$140,000 paper gain can still leave no estimated cash proceeds.
| Item | Estimated amount | How to read it |
|---|---|---|
| Original purchase price | S$520,000 | Starting purchase price. |
| Selling price after 10 years | S$660,000 | The price agreed with the buyer in this illustration. |
| Paper gain | S$140,000 | Selling price less original purchase price. This is not the same as cash proceeds. |
| Outstanding housing loan | −S$276,980 | The remaining loan is settled from the sale proceeds. |
| Balance before CPF refund | S$383,020 | Sale price after the illustrative outstanding loan is settled. |
| CPF principal used | S$327,751 | Illustrative CPF savings used for the purchase and instalments. |
| Estimated CPF accrued interest | S$66,509 | Illustrative accrued interest associated with the CPF used. |
| Total estimated CPF refund | −S$394,259 | CPF principal plus the illustrative accrued interest. |
| Arithmetic balance before selling expenses | −S$11,239 | Shows that the available sale balance is below the illustrative CPF refund figure. |
| Estimated cash proceeds from sale | S$0 | The illustration produces no cash proceeds before any separate case-specific adjustments or selling expenses are reviewed. |
CPF framing: A CPF refund is not a penalty or money disappearing. It is money restored to the owner's own CPF account, supporting retirement savings and, subject to CPF rules, future housing needs.
Note: These figures are illustrative and opinion-based, produced with calculation tools — not a valuation or financial advice. Human error is possible; verify against official sources before relying on them.
The flat sold for more than it cost, but the loan and CPF refund (which is not lost — it returns to the owner’s own CPF as retirement savings) came out first.
This is why the useful question is never “what will it sell for,” but “what will I actually keep once the loan and CPF are settled?” — and that question is worth mapping before you decide to sell, not after an offer arrives.
What is the HDB Resale Price Index?
The HDB Resale Price Index (RPI) tracks overall price movement across all HDB resale transactions.
It’s the market’s temperature — rising, slowing, or correcting — not a valuation of any single flat.
Your flat’s remaining lease, town, floor, layout and condition can all pull it above or below the index.
Two 35-year-old flats can behave very differently at sale. One near an MRT station, good schools and mature amenities may hold firm demand.
Another with weaker access or more competing supply nearby may face more resistance — same age, different outcome.
The index tells you the direction of the tide; it doesn’t tell you where your specific flat sits in it.
How has the HDB Resale Price Index moved recently?
HDB resale prices rose 9.7% in 2024 and 2.9% in 2025 — a sharp slowdown, not a reversal. Q1 2026 dipped 0.1% quarter-on-quarter, the first quarterly decline since Q1 2020, and the Q2 2026 confirmed a further 0.3% dip.
This is the market settling into a slower pace, not a signal about any one flat.
| Period | Movement | Status | Practical reading |
|---|---|---|---|
| 2023 full year | +4.9% | Final | Annual resale-price growth remained positive. |
| 2024 full year | +9.7% | Final | A stronger year for the overall resale index. |
| 2025 full year | +2.9% | Final | Growth slowed substantially from 2024. |
| Q1 2026 | −0.1% QoQ | Final | The first quarterly decline since Q1 2020. |
| Q2 2026 | −0.3% QoQ | Final · RPI 202.8 | A second consecutive quarterly decline; this describes the overall market, not any individual flat. |
Source: HDB — 2nd Quarter 2026 Public Housing Data and Upcoming Flat Supply. The HDB Resale Price Index tracks overall public-housing resale price movement and should not be treated as a valuation of a specific flat.
This isn’t the first time growth has slowed sharply after a strong run — the index has moved through several multi-year cycles since 1990, each smaller and slower than the one before.
For that full 36-year cycle history, see the three-cycle read in HDB Lease Decay.
What matters for a valuation call today is simpler: the fastest growth phase is behind this cycle, and buyers are pricing more carefully — which puts more weight on the five factors below, not less.
The five factors that decide whether an older HDB still holds value
Age alone doesn’t decide a flat’s value.
Five factors do: remaining lease, location demand, size and layout, competing supply, and next-owner exit confidence.
Not every older flat performs the same way — some hold firm because they solve a real buyer problem; others struggle because several weak signals stack up together.
The question isn’t “how old is the flat?”
It’s “what does this flat still offer that a buyer values enough to pay for?”
1. Remaining Lease
The shorter the lease, the more a buyer’s CPF usage and loan tenure tighten — which narrows the pool of people who can actually finance the purchase.
A flat with 70 years left feels very different to buyers than one with 45 years left, even if both are otherwise similar.
The financing mechanics themselves — the age-95 CPF test, the 20-year CPF floor, loan tenure limits — are covered in full in HDB Lease Decay; here, the point is simpler: a narrower buyer pool means weaker pricing power, which is a valuation fact regardless of how the mechanics work.
2. Location demand
Mature estates can still draw strong interest — transport, schools, family proximity, established amenities.
A shorter lease in a strong location can still appeal to the right buyer.
Location supports demand; it doesn’t cancel out lease decay.
3. Flat size and layout
Some older flats are genuinely larger than what’s built today — a real advantage for families needing space. But size alone isn’t enough.
Buyers also weigh usability: does the layout work for modern living, and how much renovation does it need?
A spacious flat with poor flow can undersell its own floor area.
For the fuller space-vs-lease trade-off, see Bigger Older HDB or Smaller Newer HDB?.
4. Competing supply
Your flat isn’t just competing with the unit next door.
Buyers weigh it against other resale options, BTO launches, Sale of Balance flats, private alternatives, or simply waiting.
More alternatives make buyers more price-sensitive; a flat offering something genuinely rare holds pricing power better.
5. Next-owner exit confidence
This is the most overlooked factor.
Sellers look backward — “I bought at S$350,000, I’m selling at S$650,000, that’s a good gain.” Buyers look forward — “if I buy at S$650,000 today, will this still make sense when I need to sell?”
Both are looking at the same flat from different timelines.
A pricing strategy that only tells the seller’s story misses the buyer’s.
| Factor | What buyers are weighing | What can support value | What can create pressure |
|---|---|---|---|
| Remaining lease | Financing runway, CPF usage and how long the flat still works for their own holding period. | A longer remaining lease keeps the potential buyer pool broader. | A shorter lease can narrow the pool of buyers who can comfortably finance the purchase. |
| Location demand | Transport, family proximity, schools, amenities and everyday convenience. | A location solving a real buyer need can keep demand resilient. | Weak accessibility or easily substituted locations can increase price resistance. |
| Size and layout | Usable living space, room proportions, renovation needs and whether the layout fits modern family life. | Large, practical layouts can remain attractive even when the flat is older. | Awkward layouts or heavy renovation requirements reduce the benefit of extra floor area. |
| Competing supply | Other resale units, newer MOP flats, BTO and SBF choices, and alternative property types. | A genuinely differentiated unit has fewer direct substitutes. | More comparable choices give buyers more room to negotiate or wait. |
| Next-owner exit confidence | Whether today's purchase still looks workable when that buyer eventually needs to sell. | A sensible entry price and broad future buyer appeal support confidence. | A high entry price combined with a narrowing future buyer pool can make buyers more cautious. |
The useful question is not simply how old the flat is. It is what the flat still offers that the next buyer values enough to pay for.
Why do some older HDB flats still sell well?
Older flats that continue to sell well usually solve a specific buyer need — proximity to parents, a school within 1km, more space than a newer unit offers, or a mature estate a buyer doesn’t want to wait years for.
The flat isn’t just an ageing asset; it’s a practical solution for the right buyer.
Broad claims like “good location” or “rare size” don’t do the selling.
The value has to be explained in buyer terms: who is the likely buyer, what problem does this flat solve for them, what will they compare it against, and what gives them confidence despite the lease.
The older the flat, the more that explanation carries the price.
Why do some HDB flats face more pressure over time?
Pressure builds when several weak signals stack together — a shorter lease, a less convenient location, heavy renovation needs, an inefficient layout, many nearby competing flats, and a high asking price relative to newer alternatives.
Buyers may still like the flat but hesitate on price.
A flat that grew well in value since purchase doesn’t guarantee the next buyer shares the seller’s optimism.
Buyers pay for their own future risk and options, not the seller’s past gain — which is why pricing should track what today’s buyers can and will support, not what neighbours achieved before.
How do cooling measures affect buyer affordability and value?
Government cooling measures shape resale demand by adjusting what buyers can borrow.
In August 2024, the HDB loan-to-value limit was lowered from 80% to 75%, meaning eligible HDB-loan buyers generally need a larger upfront cash/CPF outlay.
Bank loans were already at 75% LTV under standard conditions and were not affected by this change.
That single change tightens buyer budgets across the board — interest and viewings can stay strong, but the real test is whether buyers can comfortably finance the price being asked, not just whether they like the flat.
Effective 20 August 2024, 12.00am: HDB / MND — “Measures to Cool the HDB Resale Market and Provide More Support for First-Time Home Buyers”.
What is Cash Over Valuation (COV), and why is the highest offer not always the safest?
COV is the amount a buyer pays above HDB’s official valuation of the flat — for example, S$620,000 agreed against a S$600,000 valuation is S$20,000 COV.
It must be paid entirely in cash; CPF and the housing loan are calculated against the valuation, not the agreed price.
A high offer backed by weak cash buffer is a shakier deal than it looks.
Since HDB’s 2014 process change, buyers and sellers agree on a price before the valuation is revealed — which shifted the negotiation from “haggle over COV” to “agree a price, then find out the COV.”
Buyers can still stretch in a tight market, but most think carefully before overcommitting cash that can’t be financed.
For sellers: the highest offer isn’t automatically the strongest one.
A strong offer is backed by realistic financing and a buyer with genuine cash buffer — not just the biggest number on paper.
Confirmed directly against HDB’s own pages: buyer and seller mutually agree on the resale price before the Option to Purchase is granted; HDB accepts a Request for Value only after the OTP has been granted, and that valuation — not the agreed price — is what CPF usage and any housing loan are based on.
That’s the mechanism confirmed at the source.
Should I rely on SERS or VERS to protect my flat's value?
No. SERS is discretionary and rare — around 4–5% of flats identified since 1995 — and cannot be assumed for any specific flat.
VERS is voluntary and still being finalised.
Pricing a flat on the hope of either is a planning risk, not a strategy.
Some owners of older flats hope their block will eventually be selected for SERS, or that VERS will deliver a similar windfall.
Both are real schemes, but neither should sit inside a valuation.
For the full mechanics — how each scheme works, eligibility signals, and the compensation differences — see What are SERS and VERS — and will my flat qualify? in the lease decay pillar, and the fuller estate-renewal picture in Singapore HDB: VERS Takes Shape.
Your pricing and exit decision should hold up whether or not either scheme ever reaches your precinct.
Why supply and demand still decide value, not just lease
Lease matters, but it’s not the only lever.
More BTO supply or a wave of newer resale flats can pull some buyers away from older stock; strong location or family needs can pull demand back.
Every flat has to be judged against its real alternatives, not age in isolation.
A 4-room flat in one town may face heavy competition; a similar flat in another estate may have a deeper buyer pool.
A large older flat can still stand out against smaller newer alternatives.
A newer MOP flat can still struggle if it’s priced past buyer comfort.
Market value is decided by buyer alternatives, not age alone.
Market value and personal value are not the same
To an owner, a flat carries memories, renovation effort, and a sense of home.
To a buyer, it’s a future commitment — price, lease, renovation cost, financing, and their own eventual exit.
Neither view is wrong; they’re simply looking from different points in the same journey.
A sound selling strategy respects both — protecting the value of the home while presenting it in terms a buyer can trust and act on.
Sellers who only tell their own story tend to leave value on the table; the ones who also answer the buyer’s question price and sell better.
Should you sell before your HDB depreciates?
This isn’t really a timing question — it’s a value-factor question.
Where does your flat sit on the five factors, what would your real cash position be after loan and CPF refund, and how does that compare with your next step?
Selling early isn’t automatically smarter; holding longer isn’t automatically wrong.
The lease-timing version of this question — how much CPF and loan runway you have left, and when financing pressure starts to bite — is answered in (What can I do if my flat’s lease is running down) in the lease decay pillar.
Here, the question is narrower and valuation-only: given the five factors and your real cash math, does selling now or later put you in a stronger position with the next buyer pool?
Simple holding vs selling scenarios
| Position | What you may be seeing | Practical next step |
|---|---|---|
| Hold | Your flat still performs reasonably across the five factors, still suits your household, and selling now does not materially improve your next move. | Staying put can be a reasonable choice. Keep the numbers reviewed rather than moving simply because the flat is older. |
| Review soon | Competing supply is increasing, one or more value factors are weakening, or you are unsure how much usable cash and CPF you would have after a sale. | Map the estimated selling range, outstanding loan, CPF refund and next-home requirement before making a decision. |
| Consider selling | Your flat still has genuine buyer demand, the estimated proceeds support a workable next step, and your own plans make a move worth evaluating. | Compare selling with holding using your actual numbers, timeline and next-home needs. Do not base the decision on a general market rule. |
This is a decision framework, not a recommendation to sell or hold. The appropriate next step depends on the property, household circumstances, financing and future housing plan.

Conclusion: do not panic, but do not ignore it
If you own an HDB flat — especially one with a shorter remaining lease — it’s worth reviewing where it stands on the five factors early. Not because you must sell.
Because time affects your options, and buyer demand tends to narrow gradually rather than all at once.
What's left is the part no article can do — how these value factors apply to your flat, your numbers, your timing. One session with Rick closes that gap.

Frequently asked questions
At what age does an HDB flat start to depreciate?
There is no single birthday when every HDB flat starts losing value. What matters is how remaining lease, location demand, size and layout, competing supply, and the next buyer's future exit considerations come together. Two flats of the same age can therefore attract very different demand.
Do old HDB flats still hold value in Singapore?
Some older flats continue to attract strong demand because they solve a specific buyer need, such as family proximity, more living space or access to an established location. That does not remove lease-related considerations, and the outcome varies from flat to flat.
What is Cash Over Valuation, and how does it affect my sale?
Cash Over Valuation, or COV, is the difference when an agreed resale price is above HDB's determined value. HDB's current resale process requires the buyer and seller to agree the price and obtain an Option to Purchase before a buyer using CPF or financing submits a Request for Value. The HDB value then forms the basis for CPF usage and/or the financing reference. Check HDB's Request for Value process.
Is a bigger older HDB always a better deal than a smaller newer one?
No. A bigger older flat may give you more usable space for the budget, while a smaller newer flat gives you more remaining lease. The better fit depends on your household, renovation budget, expected holding period and future buyer pool. Compare a bigger older HDB with a smaller newer HDB.
How does the HDB Resale Price Index differ from my flat's actual value?
The HDB Resale Price Index tracks overall resale-price movement across the public-housing market. It does not value an individual flat. In Q2 2026 the index fell 0.3% quarter on quarter, after a 0.1% decline in Q1 2026, but your own flat may perform differently because of lease, town, floor, size, layout, condition and competing supply. See HDB resale statistics.
Should I sell my HDB before it loses more value?
Not automatically. A useful review starts with the five value factors, your estimated selling range, outstanding loan, CPF refund and what the next home would require. Selling earlier is not always better, and holding longer is not always wrong.
Can I rely on SERS or VERS to protect an older HDB's value?
No. SERS is selective and should not be assumed for a particular block. VERS is a separate redevelopment framework for older estates and should not be built into today's asking price or exit plan. Your decision should still work even if neither scheme applies to your precinct. Read the YouHome guide to SERS and VERS planning.
Next steps
If you’re weighing an older flat’s value — whether to sell, hold, or how it might perform against the next buyer pool — the useful move is mapping the five factors and your real cash position before deciding.
For the lease-specific side of this (CPF runway, loan tenure, what happens at lease expiry, SERS/VERS mechanics), the companion piece has the full picture.
