Private condominium and apartment projects only: Executive Condominiums have their own directory and landed homes their own guide. Every figure is a caveated transaction from URA; medians are over the stated window; "sales since" counts the records we hold (URA publishes about five years). HDB figures are resale transactions from data.gov.sg in the last 12 months. Map positions come from URA's caveat coordinates.
Prices are caveats lodged with URA and can lag completed deals by weeks; medians are of the sales in the stated window and a project with few sales can swing. Growth and momentum compare medians, not the same units. Positions and building outlines are approximate. HDB figures are resale transactions from data.gov.sg. Lease left is counted from the lease start in URA's records. Nothing here is financial advice.
