Median price per square foot by walking distance to the nearest station, indexed so condos and HDB share one axis. Tap your own walking distance:

HDB flats are 99-year leaseholds — value falls as the lease runs down. “Bala’s Table” is the government’s official decay schedule; teal is what buyers actually paid.

Same flats, different floors: the premium buyers pay per storey band, across every HDB resale in 12 months.

Homes within 1km of a primary school get P1 registration priority — the dumbbell runs from the price just outside the ring (○) to inside it (●). Location plays a part too; this is the observed gap, not proof the school causes all of it.

Years of a typical local household’s entire income to buy the median resale flat there — the honest affordability measure. Dots on a shared scale.
