The Lease Buyback Scheme Sells S$190,000 of Lease. In HDB's Own Example, S$25,000 Reaches the Bank.

The Lease Buyback Scheme is usually described as a way to "unlock" the value of a flat. That verb does a great deal of quiet work.

In HDB's own published illustration, a couple both aged 65 sell a 35-year slice of their lease to HDB for S$190,000. Of that, S$25,000 arrives as cash. The remaining S$165,000 goes into their CPF Retirement Accounts and returns as monthly income for the rest of their lives.

That is not a flaw in the scheme. It is the scheme. LBS is a retirement-income instrument wearing the clothes of a property transaction, and almost every misunderstanding of it starts by reading the second half of that sentence instead of the first.

What you are actually selling

HDB buys the tail of your lease. You keep the front end, and the front end must be long enough to cover the youngest owner to at least age 95.

That rule sets the floor; you may retain longer if you want to sell less.

Source: HDB, Understanding the LBS. MND has confirmed that retained leases in practice "generally fell within the range of 15 to 35 years" (written answer, 12 February 2026).

One correction before going further, because it circulates constantly: LBS proceeds are computed on market value, not straight-line depreciation. The price is the flat's market value at application, less the value of the retained lease, less anything owed to HDB. A news report published the straight-line claim in August 2024; HDB flagged it, the article was corrected, and MND put the correction on the parliamentary record. Straight-line depreciation applies only to the premature surrender reimbursement — a different transaction entirely.

The eligibility fact almost everyone gets wrong

Property blogs routinely write that "at least one owner" must have reached 65. HDB's own page says the opposite.

• All owners must have reached the eligibility age, currently 65 — not one of them.
• Gross monthly household income of S$14,000 or less. Unchanged.
• At least one owner a Singapore Citizen.
• All flat types, excluding short-lease flats, HUDC units and executive condominiums.
• No concurrent private residential property; no more than one non-residential private property.
• All owners living in the flat at least 5 years — 10 years for Prime Location Public Housing flats.
• At least 20 years of lease left to sell, on top of the lease you retain.

The age threshold is pegged to the CPF Payout Eligibility Age, per HDB's December 2025 terms and conditions.

The waterfall

This is where the money goes, in order. Nothing here is discretionary.

1. Deductions. Outstanding mortgage, upgrading costs and LBS legal and admin fees come off the top.
2. Apportionment. The net figure is split by manner of holding — 50/50 for two joint tenants.
3. Mandatory CPF top-up to the specified requirement (table below).
4. Cash out, capped at S$100,000 per household.
5. Anything above that cap goes back into CPF to top each owner up to the current Full Retirement Sum.
6. Only then is the balance retained in cash, uncapped.

The specified top-up requirement for applications between 1 January and 31 December 2026:

These reset annually with the retirement sums. For members turning 55 in 2026 the Basic Retirement Sum is S$110,200 and the Full Retirement Sum S$220,400 (CPF).

HDB's own numbers, worked through

HDB's illustration: both owners 65, joint tenancy, a fully paid 4-room flat worth S$450,000 with 65 years of lease left. They retain 30 years and sell the 35-year tail for S$190,000. Their starting Retirement Account balances are S$20,000 and S$20,400.

Each must reach S$110,200. So the shortfalls are S$90,200 and S$89,800 — S$180,000 of the S$190,000 is spoken for before anyone sees a dollar.

S$25,000 of cash against a flat valued at S$450,000 — 5.6% of the asset's value, in exchange for permanently surrendering the back half of its lease. Read as a property transaction, that is a poor trade. Read as what it is — a S$180,000 lifetime annuity purchase with a S$25,000 cash rebate — it is a different proposition entirely.

Why the cash figure swings so hard

The cash you keep is not a function of your flat. It is a function of how far your Retirement Account already is from the threshold. Holding HDB's S$190,000 proceeds constant and varying only the starting balances (our computation, applying HDB's stated rules):

The inversion at the bottom is the scheme's sharpest edge. An owner who has already met the retirement sum keeps every dollar in cash — and receives no bonus at all, because HDB explicitly withholds it where no top-up is needed. The scheme pays you for being short, and pays you nothing for being prepared.

The bonus

Full bonus requires total household top-ups of at least S$60,000. It is cash, once per household ever, and there is no clawback if the flat is later returned to HDB. Where all owners have met the FRS but total top-ups still fall short of S$60,000, owners may top up MediSave or a spouse's accounts to reach the threshold.

These quanta were last raised in April 2020 — a 50% increase across all flat types. They have not moved since.

What you permanently give up

HDB's terms and conditions are blunt, and worth quoting rather than paraphrasing.

"The flat owner(s) is/ are not allowed to sell the LBS flat on the open market."

And on reversal:

"…cannot be aborted and is irrevocable… the lease of the flat cannot be reverted to its original lease term."

Beyond that: you cannot rent out the whole flat, though spare bedrooms are permitted for 3-room and larger under prevailing rules. You cannot transfer, mortgage or charge the flat without HDB's written consent. There is a 5-year bar on applying for another subsidised flat. Private property is only permitted after the MOP measured from the LBS effective date, and you must keep living in the HDB flat.

On outliving the retained lease, HDB's position is that you "will not be left homeless" and it will work out an appropriate arrangement based on family support, health and finances. That is discretionary case management. It is not a stated entitlement, and it should not be read as one.

Who is actually using it

About 16,000 households since the scheme launched in March 2009 — roughly 6,000 single-person and 7,000 two-person households (MND, 24 February 2026). Around 9 in 10 received between S$100,000 and S$300,000 in proceeds. Average 4-room proceeds plus bonus over 2021–2025 exceeded S$200,000 (MND Committee of Supply, 4 March 2026).

MND declines to publish an average payout, on the grounds that a single average across flat types and retained-lease lengths is not meaningful. Any "average LBS payout" you encounter is someone's arithmetic, not an official statistic.

Nothing about LBS changed in 2026

Worth stating plainly, because the scheme is often discussed as though it is mid-reform. Budget 2026 contained no LBS or housing-monetisation changes, and the March 2026 Committee of Supply speech restated the scheme unchanged.

What did change was the Silver Housing Bonus, effective 1 December 2025: the qualifying test moved from a cash top-up to a net increase in Retirement Account savings — fundable from CPF housing refunds — and an extra S$10,000 was added for right-sizing to a 2-room or smaller flat, taking the maximum to S$40,000 (MND). If you are comparing monetisation routes, that is the one that moved.

The honest read

LBS is the right instrument for a specific person: someone who wants to stay in the flat they are in, has a Retirement Account well short of the sum, and values guaranteed lifelong income over liquidity, flexibility and a bequest.

For anyone else, the arithmetic above is the argument against it. The cash component is small by design, the decision cannot be reversed, and the asset stops behaving like an asset — it becomes a depreciating right to occupy. Right-sizing keeps a saleable flat and, since December 2025, a larger bonus. Renting a spare bedroom keeps everything.

The scheme is not a trap. But it is not what "unlocking the value of your flat" sounds like either, and in HDB's own example the gap between those two readings is worth S$165,000.
