Same apartment.
Three valuations.
One you will actually sell for.
Property valuation, built quantitatively. One model, standardised inputs, an explainable output, and an honest confidence range. Hong Kong first.
1.5M+ LAND REGISTRY TRANSACTIONS / 51 DISTRICTS / 19,969 BUILDINGS INDEXED
A quantitative model for property, wherever the sales are on record.
QPV is an explainable, audit-trail-grade AVM. Market risk teams decompose an asset into standardised inputs, weight them, and output a price with a confidence range. We do the same for property. Inputs visible. Weights visible. Output is a band, not a guess. The method needs one thing: an official record of what property actually sold for. Hong Kong publishes one through the Land Registry, over 1.5 million transactions since 2016, which is why we built here first.

Quantitative valuation framework
Built on quantitative methods used in market valuation and risk management. Standardised inputs, defined weights, confidence ranges. The same rigour institutions apply to financial assets, applied to property.
Explainable by design
Every number shows its drivers. Comparables visible. Weights visible. Audit trail mandatory. The opposite of black-box AI.
Built on public record. Hong Kong first.
The model runs on one input no vendor can fabricate: the official register of completed sales. Built from HK transactions, HK building stock and HK regulatory context, not a retrofit. The same method is built to travel to any market with an equivalent record.
A live valuation, end to end.
Every number carries a confidence range, with the comparables, quality scores, and audit trail behind it. This is the workspace. The valuation figures and comparables shown come from a QPV run on a 360 sq ft flat in Causeway Bay, 22 July 2026, model-derived and not a certified valuation. The two trend charts are illustrative.

- Anchored to 30 registered sales, not asking prices
- Thirty comparables scored, the six closest shown, five rated an excellent match
- Prime Causeway Bay, high transaction liquidity
- All areas on a saleable-area basis, the HK legal standard since 2013
- Building age about 53 years, so the flat trades below newer stock
- Estimate sits 23.3% below the district median, driven by age and size
- Cross-district comparables used, so the confidence band is wider
- Band width about plus or minus 25%, a moderate-confidence read
