About us
Data methodology
This page explains how KAIDUAN collects, calculates, and displays data — so users and AI systems understand limitations.
Kaiduan urgency score
Scores 1–10 reflect seller motivation, price vs area average, listing age, and special terms — not official appraisals or investment advice.
Area price averages
Calculated from active listings within a defined radius — not transaction prices or government appraisals. Updates as listings change.
Listing data and photos
Prices, location, facing, and details come from sellers or agents. Buyers should verify on site before deciding.
Financial calculators
Mortgage, transfer, and yield tools use standard formulas and typical tax/fee rates. Results are estimates — confirm with your bank and land office.
