HDB dates a resale by when it was registered. Its published data starts in January 2017; this page shows the past five years. Blocks with fewer than 10 resales in that time have no page of their own. The completion year, storeys and flat counts are from HDB's list of its blocks. The 99-year lease runs from the lease start HDB records with each resale, which for most blocks is a year or two after completion.
Primary schools nearby
Nearest: SENGKANG GREEN PRIMARY SCHOOL, 227 m straight-line
Distances are straight-line, from this block (OneMap’s point for its address) to the school’s registered address. MOE measures home-school distance differently — from the school’s boundary to your building’s outline — so its official 1 km and 2 km categories will not always match what you see here. A school shown at 990 m may fall outside MOE’s 1 km category, and one at 1,010 m may fall inside it. Check OneMap SchoolQuery before making any decision that depends on the category.

MRT and LRT nearby
Nearest: Fernvale, 341 m to an exit
Distances are straight-line, from this block (OneMap’s point for its address) to the station’s nearest exit — not walking distance. Rail lines are bounded by viaducts, expressways and canals, so the real walk is often much longer. This list covers stations in service, checked by hand when the data was last synced.

Bus stops nearby
2 stops within 200 m, 14 within 400 m
Distances are straight-line from this block (OneMap’s point for its address), not walking distance, and the 200 m / 400 m bands are conventional planning catchments rather than distances measured against what buyers pay. Nearly every address in Singapore has a stop within a few hundred metres, so it is the counts that separate one place from another, not the nearest distance. The services listed are those that call at those stops. How often they run is not in this data — nine services can still mean a long wait.
