A 60-Year Lease Is Short Only If You're Young. The 95 Rule, Worked.

Ask most buyers when a lease becomes a financing problem and you'll hear a number of years — 60, maybe 50. That has been the wrong axis since 10 May 2019. The rule that decides how much CPF can go into a property no longer grades the flat. It grades the pairing: does the remaining lease cover the youngest buyer until at least age 95?

The consequence is a crossover most people haven't computed. A flat with 60 years left takes unlimited CPF — up to the usual valuation limit — from a buyer who is 35, because 35 + 60 reaches 95. Hand the same flat to a 25-year-old and CPF turns away 20% of it. Same flat, same lease, different birthday. The formula is public, it is linear, and it is worth working through before you shortlist anything older than its owners.

The test, then the formula

The test, from the joint MND-MOM announcement that set the current rules: if the remaining lease covers the youngest buyer to at least 95, CPF can be used up to the Valuation Limit — the lower of price or valuation at purchase. If it falls short, CPF use is pro-rated. And below an absolute floor of 20 years of lease, no CPF can be used at all.

The pro-ration works like this:

Usable share of the Valuation Limit = (remaining lease − 20) ÷ (95 − youngest buyer's age − 20)

The 20s are the same floor appearing twice: the first 20 years of any lease are treated as spoken for, and only the coverage above that floor counts. CPF's own worked example checks out against the formula exactly: two 25-year-olds buying a S$550,000 flat with 65 years of lease get (65 − 20) ÷ (95 − 25 − 20) = 90% — the S$495,000 CPF cap the Board quotes.

Rearrange the test and you get the number that actually belongs in your shortlisting: the crossover age is 95 minus the remaining lease. Younger than that, the caps bite; at or past it, they vanish.

The same flat at five ages

Here is a S$500,000 flat with 60 years of remaining lease — priced at valuation, financed with an HDB loan — bought by buyers of different ages. The loan moves too, because the same announcement pro-rates the HDB loan-to-value limit by the same coverage share (the LTV ceiling is 75% today, cut from the 80% that applied before August 2024; the 2019 examples were written at 90%):

Two things to read off that table. First, the penalty is gentle near the crossover and steep far from it — a 34-year-old loses S$12,195 of CPF headroom; a 25-year-old loses S$100,000 of CPF and S$75,000 of loan. Second, the two caps stack: the shortfall must be bridged in cash, today, at completion. Note the loan tenure shrinks in parallel — an HDB loan runs for the shortest of 25 years, 65 minus the buyers' average age, or the lease minus 20. The press release adds one more line worth knowing verbatim: "Banks also take reference from CPF restrictions when assessing how much loan to lend."

Crossover ages for this month's actual flats

Short-lease flats are not hypothetical — four of August's record-setting transactions carry leases of 61 years or less. Computed from HDB's resale dataset, the age from which each takes unrestricted CPF:

Now run the Queenstown terrace — a record price for a 41-year lease — as a 30-year-old buyer. Coverage is 40.92 years against the 45 that matter, a usable share of 46.5%. The CPF cap is S$483,820; the HDB loan cap is 34.9% of value, or S$362,865. Even for a buyer holding S$483,820 of CPF, the minimum cash to close is about S$194,203 — nearly a fifth of the price. At 55, the same flat takes full CPF and the full 75% loan. The record buyer of a 41-year lease is almost certainly not young, and the rule is why.

The rule runs on age, and that is the point

Notice what the design does: it frees the buyers whom lease decay used to trap. Before 2019, the old rules graded the flat itself — below 60 years of lease, CPF was restricted for everyone, which pushed retirees away from exactly the cheap, short flats that suited them. The current test asks only whether the asset outlives the occupant. A 60-year-old buying that 41-year Stirling Road lease is fully covered; a 30-year-old is the one being told, in arithmetic, that the flat will expire around age 71 — some 24 years before the age the retirement rules plan for.

Three follow-on clauses complete the picture. If the property covers you to 95, you may keep withdrawing CPF above the Basic Retirement Sum from 55; if it doesn't, that withdrawal channel closes too. Buyers whose CPF-funded property does not cover them to 95 must set aside the Full Retirement Sum — not the Basic — before excess OA can fund a second property. And the computation is keyed to the youngest relevant person: CPF's cap follows the youngest buyer using CPF, the HDB loan follows the youngest buyer outright, and if the youngest co-owner later gives up ownership, the limit is recomputed on the next youngest — a detail that decoupling plans routinely miss.

Before you shortlist

The arithmetic is one subtraction: 95 minus the remaining lease. If you're older than the answer, the lease is not your financing problem — price it on its own merits, decay and all. If you're younger, run the formula before falling for the psf discount: the cap on CPF, the cut to the loan and the shrunken tenure all land on the same completion statement, in cash. CPF's housing usage calculator computes the exact figure for your ages and lease; the point of this piece is that you can see the shape of the answer before you open it.
