PropertySignals99-year leasehold explained
A 99-year lease gives ownership for a fixed term. The important number for a buyer is the lease remaining today, not the number of years printed in the original title.

The lease clock, visualised
This chart shows the illustrative lease factor used by PropertySignals' Fair PSF comparison signal. It is not a historical price forecast: actual property values also reflect location, condition, supply, demand, financing and the particular unit.
What a 99-year lease means
The lease normally runs from its original commencement, not from a resale purchase. A buyer should verify the actual remaining lease and the relevant title details. The Singapore Land Authority describes how the land register identifies whether an estate is freehold or leasehold.
Lease renewal is not automatic. SLA says renewal applications are assessed on their own merits with regard to long-term planning and other agencies' views. That makes a prospective renewal unsuitable as an assumed component of a purchase price.
Why the curve is not linear
A simple straight line would treat 50 years remaining as exactly half of a 99-year benchmark. A real purchase decision is more complicated: the next buyer's age, CPF eligibility, loan terms, property type and holding horizon all matter. PropertySignals uses a non-linear formula to make that assumption visible rather than hiding it inside a single price number.
The factor is intentionally only one input. A well-located older home can still be more suitable than a newer one; a freehold title does not make two otherwise different homes comparable.
CPF and financing are individual checks
There is no single remaining-lease threshold that answers whether a buyer can fund a home. CPF use is affected by the youngest buyer's age and the lease remaining; CPF explains that full use may be affected when the lease does not cover the youngest buyer to age 95, and that usage can be pro-rated for eligible properties. Current lender terms also vary.
Before committing, check the CPF housing usage calculator, ask the lender about the specific property and loan, and allow for a cash buffer. Do not use an illustrative curve as a financing decision.
SERS, renewal and collective sales
SERS is a highly selective HDB redevelopment programme involving compulsory acquisition; it is not a general assurance that an ageing flat will be redeveloped. HDB's current page says there are no plans for more SERS projects because most projects with high redevelopment potential have already been selected.
A private residential project can pursue collective sale or a lease-renewal application in the relevant circumstances, but neither outcome is automatic. Read the official policy, the sale documents and project-specific information rather than treating a possible future redevelopment as guaranteed value.
How different buyers can use this information
- First-time buyers: compare the home to your planned holding period, affordability and ability to finance it.
- Upgraders: consider the remaining lease at both entry and a plausible future exit date, together with your next purchase plan.
- Investors: compare rental demand, vacancy, expenses and resale liquidity; remaining lease alone does not determine return.
Frequently asked questions
Does a 99-year lease restart when I buy resale?
No. The relevant figure is the balance of the original lease. Confirm it from the appropriate property and title records.
Can a lease be extended automatically?
No. SLA's policy is generally to allow leases to expire without renewal, while allowing case-by-case consideration where renewal fits planning intent and other conditions.
Is leasehold decay the same for every property?
No. The Fair PSF curve is an illustrative comparison model. It cannot represent every location, project, unit condition, funding profile or market cycle.
