Every number shows its working.
Each tool states the formula and the rule it comes from, so you are never just trusting a black box.
How our numbers work
Real transactions, your own street
The HDB valuation learns from about 989,000 resale prices since 1990, then adjusts the recent sales on your street to your exact flat.
Confidence you can check
Every estimate carries a High, Medium or Low label, tested against sales the system had never seen.
