Medians require at least 5 records per displayed group. History includes different sale dates, sizes, floors, leases and conditions; it does not measure price appreciation or the value of a particular home. The current month may be incomplete. Flat types have separate summaries so their different layouts are not treated as interchangeable.

Official historical records are supplied by HDB/data.gov.sg and URA. Dates retain source precision. Price per square foot uses each record’s stated area basis; land area, strata area and multi-unit sales are labelled and may not be directly comparable. Original fields, quality flags and source provenance remain available on every row.
