Trust Reports for Developers, Brokers & Platforms

Your Buyers Need Evidence, Not Just Listings

01

Brokerages: agents need proof, not promises

Reputable agents want to differentiate high-quality listings from incomplete ones. But without a standardized trust signal, good data and bad data look identical. Agents need a score they can show clients.

02

Developers: trust UI takes more than a score

Displaying a single number is easy. Showing a grade breakdown with risk subscores, data gaps, government price context, and provenance requires structured data your team should not have to build from scratch.

03

Platforms: listing pages hide uncertainty

Every listing page looks the same: photo gallery, price, contact button. There is no signal about what data is present, what is missing, or how the asking price compares to state land-price references.

What if every listing explained its own reliability? bds.chat makes trust inspectable: grade, breakdown, gates, gaps, sources, and warnings — not hidden behind a single score.

What Each Report Includes

1

Trust Grade (A-F)

A single letter grade that summarizes data quality, risk level, and verification status. Easy for buyers to understand at a glance.

Composite score from quality, risk, and completenessColor-coded badge for instant recognitionComparable across all listings
2

Risk Breakdown (9 subscores)

Nine individual risk dimensions, each scored independently. Buyers see exactly which aspects of a listing are strong and which raise concerns.

Legal/title, gov ratio, land classificationPrice outlier, planning/zoning, physical dimensionsBlocking risk flags for critical failures
3

Government Price Context

Market price compared against state land prices (bảng giá đất nhà nước). Shows whether the asking price is within normal range or flagged as anomalous.
