How to read this analysis
The comparable range contains the middle 50% of observed prices; it is not a forecast or a confidence interval. Floor, condition, facing and remaining lease can materially change a home’s value. A price below a benchmark is a reason to investigate, not proof of a bargain.

Charts & price evidence
Understand what these records can tell you.
Each dot is an actual sale. Separate charts keep property types, area bases, sale categories, unit counts and tenures apart. Different sizes and property conditions can still explain price differences; these are not like-for-like growth charts.

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.
