A 99-year leasehold property loses value slowly at first, then rapidly once the remaining lease falls below 60 years — a non-linear curve known as Bala's Table. CPF usage tightens, bank financing shrinks, and the buyer pool narrows sharply as the lease shortens. This guide shows you how to plot your property's decay trajectory and act before the two major financing cliffs arrive.
Most buyers focus on price per square foot, proximity to MRT, and renovation costs — and then discover, sometimes too late, that the lease countdown was quietly eroding the asset underneath them. A brand-new 99-year leasehold unit purchased in 2026 behaves almost identically to a freehold property for its first two or three decades. But the same unit at year 50 of its lease, with 49 years remaining, is already on the wrong side of a curve that accelerates sharply. Understanding how to visualise that decay — and precisely where the two financing cliffs fall — is one of the most practical analytical skills any Singapore property buyer can develop. As of 2026-06, this guide walks through the mechanics, the numbers, and the step-by-step process of assessing any specific unit's lease position.
Why Lease Decay Is Non-Linear: Bala's Table Explained
Bala's Table is the industry-standard leasehold valuation reference used by property valuers in Singapore. It was constructed by Thavolia Bala and expresses the value of a leasehold property as a percentage of its equivalent freehold value, given the years remaining on the lease. The critical insight is that the depreciation is not linear. A property with 99 years remaining retains 100% of its freehold equivalent value. At 80 years remaining, it retains roughly 92–94%. At 60 years remaining, it retains approximately 80–83%. But once the lease drops below 60 years, the curve steepens sharply: at 40 years remaining, the retained value falls to around 63–67%, and at 30 years remaining it drops further still, to approximately 50–55%. These percentages are approximations based on published tables (as of 2026-06) and valuers will apply the full interpolated curve — you should verify precise figures with a licensed valuer for any transaction.
Why does the curve accelerate below 60 years? The answer lies not in mathematics alone but in the financing ecosystem. Two hard constraints begin to bite: CPF withdrawal rules and bank loan-to-value limits. Once these constraints activate, the pool of eligible buyers shrinks, and a thinner buyer pool means lower demand and, structurally, lower prices — which is precisely what the steeper portion of Bala's Table reflects empirically. The Singapore Land Authority (SLA) confirms that at the end of the lease term, the property reverts to the State with no compensation to the owner. You can verify tenure details for any property via the Singapore Land Authority at sla.gov.sg.
Freehold and 999-Year Leasehold: The Contrast
A freehold or 999-year leasehold property, by definition, has no meaningful lease decay within any practical investment horizon. A 999-year lease started in 1900 still has 873 years remaining — functionally infinite for valuation purposes. This is why freehold properties in comparable locations command a persistent price premium over 99-year leaseholds. That premium is not irrational sentiment; it is the present-value equivalent of avoiding the steepening decay curve. For buyers who plan to hold for 10–15 years and sell before the sub-60-year cliff, the premium may not be worth paying. For buyers who intend to hold into retirement or pass the property to children, freehold or 999-year tenure changes the calculus entirely. Use the price heatmap to compare transacted prices across districts and tenure types side by side.
A 99-year leasehold property does not lose value in a straight line — it follows a curve that starts gentle and then accelerates dramatically. A property with 60 years remaining retains about 79% of freehold value. At 30 years, it drops to 46%. And below 20 years, CPF cannot even be used for purchase, making the property extremely hard to sell.
The lease decay Visualizer plots this curve using Singapore's official Bala's Table, showing exactly where your property sits on the depreciation curve and when the critical thresholds hit.
What This Calculator Does
Understand how leasehold property values diminish over time using Singapore's Bala's Table. Compare 99-year, 999-year, and freehold properties side by side. See the critical CPF eligibility threshold and learn when lease decay accelerates — essential knowledge for any leasehold buyer.

Why This Matters
Lease decay is the number one risk in 99-year leasehold property that many Singapore buyers ignore or underestimate. The decay is not linear — it accelerates dramatically in the final decades. This calculator matters because:
- A property with 60 years remaining may retain only 70-75% of its freehold-equivalent value
- CPF usage restrictions kick in as remaining lease shortens, shrinking your buyer pool at exit
- Understanding the decay curve helps you decide whether the freehold premium is justified
What You Will Discover
After running this calculator with your personal numbers, you will know:
- A visual decay curve for 99-year, 999-year, and freehold properties
- Where your property sits on the decay curve based on its current remaining lease
- The critical CPF eligibility threshold and when your property crosses it
- How much value your leasehold property has already lost compared to freehold equivalent
- Whether lease decay will outpace appreciation over your planned holding period

Worked Example
Meet David, evaluating a 99-year leasehold condo that is 20 years old (remaining lease: 79 years). He wants to understand how much value has already decayed and what happens over the next 20 years.
The decay reality: At 79 years remaining, the property retains approximately 74.6% of its freehold-equivalent value. CPF can still be used because the remaining lease exceeds the minimum threshold. However, if David holds for 20 more years, the remaining lease drops to 59 years — entering the accelerated decay zone where value drops significantly faster.
The key question: Will capital appreciation outpace lease decay? The visualizer shows both curves so David can see exactly when decay overtakes growth — the point at which holding becomes value-destructive.
Real-World Scenarios to Try
Here are some realistic scenarios you can plug into the calculator right now. Each one reflects a common situation Singapore property buyers face.
| Scenario | Settings to Try | What You Will Learn |
|---|---|---|
| Young lease | $1.5M, 90 years remaining | How minimal the decay is when the lease is still long — and when it starts accelerating |
| Mid-life lease | $1.2M, 60 years remaining | The tipping point where banks start reducing LTV and value drops sharply |
| Ageing lease | $800K, 40 years remaining | How quickly value erodes and whether the price discount justifies the risk |
Expert Tips and Common Pitfalls
💡 Pro Tips
- Use realistic assumptions — Singapore condo appreciation has historically averaged 2-4% per year. Avoid overly optimistic projections. When in doubt, use 3% as a baseline.
- Watch the 60-year cliff — Lease decay accelerates dramatically once remaining lease drops below 60 years. The value loss per year roughly doubles compared to the first 40 years.
- Know the CPF 20-year cutoff — If the remaining lease at your age + 95 is below 20 years, CPF usage is restricted or blocked entirely. This reduces your buyer pool.
- Justify the freehold premium — Use this visualizer to see if the premium for freehold (typically 10-20%) is justified by the value preservation over your holding period.
⚠️ Common Pitfalls
- Ignoring the remaining lease at point of sale — Many buyers focus on today's remaining lease but forget it will be 10-15 years shorter when they sell. Model the exit, not just the entry.
- Assuming "999-year is the same as freehold" — While practically similar, some banks and CPF rules treat them differently. Do not assume they are interchangeable.

The Two Financing Cliffs Every Buyer Must Know
Cliff 1 — CPF Withdrawal Restrictions. The CPF Board imposes a lease coverage rule: the remaining lease of the property at the time of purchase must be able to cover the youngest buyer to at least age 95. If it cannot, CPF Ordinary Account savings cannot be used to pay for the purchase or service the monthly instalment at all. If the remaining lease covers the youngest buyer to between age 95 and their current age plus 20 years, CPF usage is pro-rated and capped accordingly. In practical terms, a 35-year-old buyer purchasing a property with only 50 years remaining on the lease faces meaningful CPF restrictions — 35 + 50 = 85, which is below the 95-year threshold — and may find that CPF funds are either partially restricted or entirely unavailable. You can verify the current rules directly via the CPF Board's home ownership guide at cpf.gov.sg. This restriction immediately shrinks the buyer pool for any property below a certain lease threshold, because a large proportion of Singaporean buyers rely on CPF for both down payment and monthly servicing.
Cliff 2 — Bank Financing and Loan-to-Value Tightening. The Monetary Authority of Singapore (MAS) regulates maximum loan-to-value (LTV) ratios and loan tenure rules. Under current guidelines, the maximum loan tenure cannot exceed the difference between 75 years and the borrower's age, or the remaining lease minus 5 years — whichever is shorter. In practice, once a property's remaining lease falls below approximately 35–40 years, most borrowers find that the maximum loan tenure available drops to 20 years or fewer, which raises monthly instalments significantly and effectively prices out buyers who do not have large liquid reserves. Some banks tighten further and apply internal overlays beyond MAS minimums. Review the current MAS property financing rules at the Monetary Authority of Singapore at mas.gov.sg.
Worked Illustration (as of 2026-06). Consider a hypothetical 99-year leasehold condominium whose lease commenced in 1990. As of 2026, that property has approximately 63 years remaining. Using Bala's Table benchmarks, it retains roughly 80–83% of its freehold-equivalent value at this point — the CPF cliff has not yet arrived for most buyers, and full bank financing is still accessible. Fast forward 15 years: the same property in 2041 would have ~48 years remaining. At that point, a 35-year-old buyer would face CPF restrictions (35 + 48 = 83, below 95), and bank loan tenures would be compressed. The property may transact at 67–70% of freehold value (using Bala benchmarks as a guide — verify with a licensed valuer). Now contrast with a 1980-vintage property that already has only ~53 years remaining in 2026. Both CPF restrictions and financing tightening are already present for younger buyers today. These illustrations use published reference tables; actual market prices also reflect location, condition, and demand, and should be cross-checked against recent transacted data for comparable properties in a given district (see district-level price data for a worked example).
Use the ShiokNest Lease Decay Calculator to model the projected retained-value percentage and remaining CPF/LTV accessibility for any specific commencement year and buyer profile. The calculator applies Bala's Table interpolation and the CPF age-95 rule interactively.
Step by Step: Assessing a Specific Unit's Lease Position
- Verify the lease commencement date and tenure. Do not rely on the listing agent's stated “years remaining” figure — it may be approximate or calculated from the wrong start date. Obtain the property's title information from the SLA via sla.gov.sg. The lease commencement date is stamped on the title deed. For HDB flats, the lease start date appears on the HDB flat listing or sale completion documents. Subtract the commencement year from the terminal year (commencement year + 99) and then subtract today's year to get the precise years remaining.
- Plot your position on Bala's Table. With the years-remaining figure in hand, open the Lease Decay Calculator and enter the commencement year and property type. The calculator will output the Bala's Table retained-value percentage, the projected value at your intended exit year, and annotate both the CPF coverage threshold year and the financing cliff year. Screenshot or export this output — it is the core of your lease-decay analysis.
- Apply the CPF age-95 test to every buyer in your household. Take the age of the youngest intended co-owner or co-borrower. Add the years remaining on the lease. If the sum is below 95, expect CPF restrictions. For example: youngest buyer aged 28, lease remaining 60 years → 28 + 60 = 88 → below 95 → pro-rated CPF use only. Repeat this for every realistic future buyer you plan to sell to, because their CPF access (or lack of it) directly affects your future exit price. Refer to the CPF withdrawal eligibility guide for the current pro-ration formula.
- Run the bank financing stress test. Determine the maximum loan tenure available to a hypothetical future 35-year-old buyer at your intended exit year. Formula: min(75 − 35, years_remaining_at_exit − 5) = min(40, years_remaining − 5). If the result is below 25 years, expect materially higher monthly instalments for future buyers and a corresponding drag on achievable sale price. This is the point at which the buyer pool narrows most sharply in practice. Cross-reference with the MAS housing loan framework to verify current maximum tenure and LTV rules.
- Compare against the district's freehold benchmark. Navigate to the price heatmap and filter for both leasehold and freehold transactions in your target district and property type. Calculate the observed leasehold-to-freehold discount in that micromarket. If the market discount is materially narrower than Bala's Table suggests (i.e., the leasehold is priced close to freehold), the property may be fully priced and the decay risk is not yet reflected — which is relevant to your entry price negotiation. If the market discount is already steep, you may be buying in at a Bala-adjusted price, limiting further decay risk in the near term.
- Model your exit scenario explicitly. Decide on a realistic holding period (5, 10, or 15 years). Re-run the Lease Decay Calculator with your exit year as the target. Check whether CPF restrictions or bank financing tightening will have activated by that exit year for the average buyer. If either cliff is crossed during your holding period, factor in a conservative price discount relative to the current Bala's Table percentage — markets often price in the approaching cliff 3–5 years before it technically arrives, compressing capital gains further. For total holding-cost context including stamp duty, mortgage servicing, and estimated exit proceeds, the Total Cost of Ownership Calculator models the full picture.
Frequently asked questions
Does Bala's Table apply to HDB flats the same way it applies to private condominiums?
Bala's Table was originally developed for private leasehold properties and is most directly applied by valuers in that context. For HDB flats, the lease decay dynamic is real and broadly follows a similar non-linear pattern, but there are additional policy layers: HDB resale flat purchases are subject to CPF's Lease Coverage rules (the youngest buyer must be covered to age 95 by the remaining lease) just as private properties are, and the MAS financing rules apply equally to HDB loans taken from commercial banks. However, HDB concessionary loans have their own tenure and eligibility criteria governed by HDB directly. In practice, valuers assessing HDB flats for bank loan purposes do apply Bala-style adjustments. As of 2026-06, you should verify current HDB-specific rules with an HDB-approved valuer or directly via the HDB portal, as policies are periodically updated.
If I buy a 99-year leasehold unit near its lease start, is the lease decay risk negligible for the next 20 years?
For the first 40 years of a 99-year lease, Bala's Table shows relatively modest depreciation — from 100% to roughly 85–90% of freehold-equivalent value. In that sense, a brand-new or early-tenure leasehold property does behave similarly to freehold for a medium-term holding horizon. However, “negligible” overstates the safety margin. Even a 5–8% retained-value differential on a $1.5 million property is $75,000–$120,000 in value eroded purely by lease passage, before any market movement. The more significant risk is that buyers who purchase near lease start and hold for 30–40 years inadvertently land in the sub-60-year zone, where decay accelerates and the financing cliffs begin to appear on the horizon for future buyers. Model your intended holding period explicitly using the Lease Decay Calculator rather than assuming early-tenure leasehold is risk-free.
Can a leasehold property be topped up to extend the lease, and does that reset the decay curve?
Lease top-ups for private residential properties are not a standard or readily available mechanism in Singapore. Unlike HDB flats — where the government has run specific lease buyback and top-up programmes in selected precincts under the Selective En-bloc Redevelopment Scheme (SERS) or related initiatives — private leasehold properties depend on collective en-bloc redevelopment as the primary exit route before lease expiry. If an en-bloc sale succeeds and the site is redeveloped, a new 99-year lease may be granted on the redeveloped property, effectively resetting the clock for new buyers. However, en-bloc outcomes are uncertain, depend on collective agreement among all owners, and are subject to the Urban Redevelopment Authority’s approval. Counting on en-bloc as a lease-decay mitigation strategy carries significant execution risk. Check the SLA website at sla.gov.sg for the current lease management framework for private properties.
How does the CPF pro-ration formula work in practice for a property with 55 years remaining?
When the remaining lease does not cover the youngest buyer to age 95 but does cover at least the buyer’s current age plus 20 years, CPF usage is pro-rated rather than fully blocked. The CPF Board calculates the maximum CPF withdrawal as: (remaining lease / (95 minus the buyer’s age)) multiplied by the property’s purchase price or valuation, whichever is lower. For a 30-year-old buyer and a property with 55 years remaining: 55 / (95 − 30) = 55 / 65 = approximately 84.6%. That buyer can use CPF for up to roughly 84.6% of the property value instead of the full amount. The remaining purchase consideration must be funded in cash or with the bank loan. This pro-ration materially affects affordability for buyers who are highly CPF-dependent and is a significant reason why properties below the lease-coverage threshold transact at a discount. Always verify the exact formula with the CPF Board directly, as the formula and thresholds can be updated by policy changes.
What happens to a leasehold property when the lease actually expires?
When a 99-year lease reaches its terminal date, the property automatically reverts to the State — specifically to the Singapore Land Authority on behalf of the government. There is no automatic compensation to the owner at that point. The land is reclaimed and the improvements (the building) are treated as part of the reversion. This outcome is not a hypothetical: a number of older private and HUDC estates in Singapore have already faced or are approaching lease expiry within the coming decades. The SLA provides guidance on this process and on what lessees can expect as the lease approaches its end. You can review the lease reversion framework directly at sla.gov.sg. In practice, most affected properties are redeveloped long before lease expiry — either through en-bloc sale or government acquisition under the Land Acquisition Act — but this is not guaranteed, and owners who hold to expiry receive nothing for the property itself.
