Understanding HDB Lease Decay in Singapore
The basics, in four lines
99 years, then it ends
Every HDB flat is sold on a 99-year lease from the state. An HDB flat is a depreciating asset, not freehold property.
The age-95 rule
For full CPF use, the remaining lease must cover the youngest buyer to age 95. A 35-year-old needs about 60 years left.
SERS is not a plan
Only about 4% of HDB blocks have been selected since 1995. Treat it as a bonus if it happens, never as your exit.
At zero, it reverts
When the lease expires the flat returns to HDB with no compensation. Value approaches nothing well before that point.
What changes as the lease runs down
Lease decay is not a straight line. What moves the price is not the flat ageing, it is buyers losing access to financing.
70+ yearsNo practical constraintFull loan tenure and unrestricted CPF for most buyers. Values hold well.
60–70 yearsStill comfortableFinancing is available, but younger buyers start to watch the age-95 line.
40–60 yearsThe window narrowsLoan tenure gets capped by the lease and CPF is pro-rated for younger buyers. The buyer pool starts shrinking.
20–40 yearsMost banks declineFinancing becomes hard to obtain and CPF is heavily restricted. Demand falls, and prices follow.
20 years or lessCPF cannot be used at allWhatever the buyer’s age. Effectively a cash purchase, with very few willing buyers.
Why it compounds. Fewer buyers can finance the flat, so demand falls, so the price falls — which is why the curve steepens rather than sloping evenly.
Before you make an offer
A flat can be freshly renovated and still be the weaker buy, because lease decay works on your financing, not on the walls.
Check the lease commencement year, not the year the block was built. They are usually the same, but not always.
Work out whether it reaches age 95 for the youngest buyer. That is the line between full and pro-rated CPF.
Ask what tenure a lender will actually offer, since the lease caps it as well as your age.
Do this before you offer. Found at valuation stage, a CPF or tenure shortfall has to be covered in cash.
Mature estates vs newer towns
A four-room flat in Toa Payoh or Ang Mo Kio may have 55 to 60 years left. A comparable unit in Punggol or Tengah can be close to 95. A lower price in an older estate does not always mean a lower monthly cost.
Queenstown, Toa Payoh, Bishan, Ang Mo Kio
Leases largely granted between the 1970s and 1990s, so the remaining years matter to your financing now rather than later.
Punggol, Sengkang, Tengah
Launched on fresh 99-year leases, so decay does not touch CPF or loan tenure for decades yet.
When this does not matter much
You are paying mostly or fully in cash, so CPF limits and tenure caps do not bind you.
You intend to stay long term and resale value is not part of the plan.
The lease is long relative to your age.
It becomes a real factor the moment CPF usage, loan tenure or a future sale enters the decision. The same flat can be fine for one buyer and a financing problem for another, purely because of age.
What this calculator needs
Three things: the lease commencement year, the flat’s current value, and the age of the youngest buyer. From those it works out the remaining lease, shows how value could move as it shortens, and flags where CPF usage and loan tenure become restricted. The lease commencement year appears on the HDB resale listing and on your title documents.
FAQ
Frequently Asked Questions
It is staged rather than sudden. Above 70 years there is no practical constraint and values hold well. Between 40 and 60 years the window narrows: loan tenure starts being capped by the lease and CPF is pro-rated for younger buyers, so the buyer pool begins to shrink. Below 40 years most buyers cannot obtain a normal mortgage, and at 20 years or less CPF cannot be used at all - which is what drives the steep part of the curve.
Yes, but it becomes very difficult. Buyers must pay almost entirely in cash since banks generally will not provide loans for flats with less than 30 years remaining. CPF usage is also severely restricted. Your buyer pool is essentially limited to cash buyers - often investors or older buyers looking for a short-term home - and prices reflect this limited demand.
SERS selection is not guaranteed. Only about 4% of HDB blocks have been selected since 1995. While SERS offers attractive compensation (typically a new flat at subsidised prices), banking on it is risky. A practical approach is to plan as if SERS will not happen - sell while your flat still has enough lease for buyers to obtain financing. If SERS is announced, treat it as a bonus.
If you are selling an older flat to upgrade, lease decay directly impacts your sale proceeds and therefore your upgrade budget. A flat bought in 1990 has roughly 63 years remaining in 2026 - still within the financing window but approaching the zone where buyer hesitation increases. Use our upgrade planner to see how your sale proceeds translate into condo buying power. Selling sooner (while remaining lease is above 60 years) generally yields better proceeds.
When the 99-year lease expires, the flat reverts to HDB and the land returns to the state. Owners receive no compensation. The flat is essentially worthless at lease expiry. This is why planning your exit well before the lease runs down is critical - check your flat's current market value with our HDB valuation tool.
CPF usage is pro-rated when the remaining lease doesn't cover the youngest buyer to age 95. For example, a 30-year-old buyer needs at least 65 years remaining for full CPF usage. Below 20 years remaining, CPF cannot be used at all.
No. SERS (Selective En Bloc Redevelopment Scheme) offers replacement flats and compensation. VERS (Voluntary Early Redevelopment Scheme) was announced in 2018 but no flats have been selected yet. VERS is meant for flats with 50+ years remaining. Neither should be relied upon as an exit strategy.
Yes. Loan tenure is capped by the flat's remaining lease as well as by your age, so a flat with fewer years left often means a shorter loan and a higher monthly instalment even when the asking price is lower. MSR (30%) and, for bank loans, TDSR (55%) still apply on top of that, so a lease-capped tenure can push you against those limits faster than you expect.
It can be. Mature estates such as Toa Payoh, Ang Mo Kio, Bishan and Queenstown commonly carry leases granted between the 1970s and 1990s, so a four-room unit there might have only 55 to 60 years left while a comparable flat in Punggol or Tengah is closer to 95. That difference can trigger CPF pro-rating and shorter loan tenures decades earlier. The flat is not necessarily a bad buy - it just needs to be priced and financed with the remaining lease in mind.
Not for a long time. A BTO flat starts on a fresh 99-year lease, so there is decades of runway before the remaining lease affects CPF usage or loan tenure. It becomes relevant when you come to sell, because your buyer's financing will be assessed against the lease that is left at that point rather than the lease you started with.
Start with the lease commencement year, which is not always the same as the year the block was built. Work out the remaining lease from there and check whether it covers the youngest buyer to age 95, since that is the threshold for full CPF usage. Then ask what loan tenure a lender will actually offer on that flat. Doing this before you make an offer avoids discovering a CPF or tenure shortfall at valuation stage, when it has to be covered in cash.
