About this number
Normalized PSF uses Bala's Table - the Singapore Land Authority differential premium reference for valuing leasehold against freehold. Bala values a fresh 99-year lease at 96% of freehold; the curve drops non-linearly, reaching ~75% at 50 years remaining and ~60% at 30 years.
Below 40 years remaining we stop normalizing because the curve diverges from market reality once CPF withdrawal restrictions and bank LTV cliffs dominate.
A separate 5% adjustment applies to projects whose lease commenced before 2023, reflecting the older strata-area measurement convention (which counted air-con ledges and bay windows).
