PRODUCT

Every QPV valuation, end to end.

Hong Kong property AVM, end to end.

Point estimate, confidence band, selected comparables, full audit trail. Delivered in seconds, reproducible six months later.

THE PROBLEM

Most property markets have no standard way to price property.

Hong Kong is where we started. HK$1.91 trillion sits in outstanding HK mortgages (Global Property Guide, October 2025) with no independent pricing reference. The same apartment gets different valuations depending on who prices it. Manual desktop valuations still dominate a market moving towards regulated, standardised benchmarks.

WHY NOW

Three things changed at the same time.

Three independent shifts in the Hong Kong property and banking landscape, all within fourteen months of each other, opened a window for institutional-grade valuation infrastructure.

HOW IT WORKS

Three steps. Explainable. Auditable.

Every valuation is reproducible. Every input visible. Every output comes with a confidence range, not a single number.

01

Filter

Five automatic data-quality checks remove outliers, duplicates, and non-comparable stock. Only verified transactions enter the model.

02

Score

Comparable properties ranked by location, size, age, and floor. Condition scored from listing photos. Recent sales weighted more heavily. Closest comparables selected by similarity score.

03

Measure

Output is a price band, not a point estimate. Tighter data means tighter range. Sparse data means wider range. Risk teams see uncertainty, not false precision.

THE PLATFORM

Valuations, comparables, audit trail in one workspace.

Every output has its drivers visible. Every comparable is one click away. Every valuation can be exported as a PDF client report. The valuation figures and comparables shown come from a QPV run on a 360 sq ft flat in Wan Chai, 22 July 2026, model-derived and not a certified valuation. The two trend charts are illustrative.

Q
Strengths
  • Anchored to 30 registered sales, not asking prices
  • Thirty comparables scored, the six closest shown, five rated an excellent match
  • Prime Wan Chai, high transaction liquidity
  • All areas on a saleable-area basis, the HK legal standard since 2013
Considerations
  • Building age about 60 years, so the flat trades below newer stock
  • Comparables reach back to 2015 and are restated to today's market, which adds uncertainty
  • Band width about plus or minus 25%, a moderate-confidence read
