QUANT PROPERTY VALUATION

Same apartment.
Three different valuations.
One you will actually sell for.

Hong Kong property valuation, built quantitatively.

The same apartment gets three valuations from three surveyors. QPV applies a quantitative model to Hong Kong property: standardised inputs, explainable outputs, confidence ranges.

WHAT IS QPV

A quantitative model for Hong Kong property.

QPV is the first explainable, audit-trail-grade AVM purpose-built for Hong Kong residential property. Market risk teams decompose assets into standardised inputs, weight them, and output a price with a confidence range. We do the same for Hong Kong property. Inputs visible. Weights visible. Output is a band, not a guess.

TRADITIONAL VALUATION
  1. Surveyor visits property
  2. Opinion based on experience
  3. Single number, no range
  4. Adjustment logic not written down
  5. Cannot be reproduced six months later
QPV VALUATION
  1. Transaction data filtered through 5 quality checks
  2. Top 30 comparables scored and weighted
  3. Output is a band, not a point
  4. Every weight and driver visible in the audit trail
  5. Reproducible from public inputs plus the QPV model
WHAT WE BUILT

Three pillars. No black box.

WHO IT'S FOR

One platform. Four audiences.

DATA PARTNERSHIPS

You share the data. We give you the platform.

Hong Kong property data lives in silos. Land Registry, banks, brokerages, government, portfolio holders, all fragmented. We are building partnerships with organisations who hold valuation-grade data. In exchange, you get early access to QPV: benchmark your portfolio, test your own valuations, integrate the platform into your workflow.
