Builder Trust Score

Methodology & Calculation Framework

A transparent, data-driven reliability index designed to help homebuyers make safer decisions.

What is the Builder Trust Score?

The Builder Trust Score (0–100) is a standardized reliability metric that evaluates how consistently and professionally a builder delivers projects. It uses a structured, weighted model—similar to a credit score—to measure performance across four critical dimensions: timeliness, experience, legal compliance, and public sentiment.

This score is not influenced by advertising or paid placement. Every builder is rated using the exact same formula.

The Four Pillars of Trust

1. Delivery Punctuality – 40% Weight

Homebuyers care most about getting their home on time. We evaluate a builder's average delay across past delivered projects:

Avg Delay Score Contribution
0–6 months 40 points
6–12 months 30 points
12–24 months 15 points
24+ months 0 points

Timely delivery = high reliability. Long delays = reduced trust.

2. Experience & Scale – 30% Weight

Experienced builders with multiple completed projects tend to be more reliable. We calculate:

  • 1 point per year of experience
  • 2 points per completed project
  • Capped at 30 points (to ensure fairness and avoid bias toward very large developers)

This rewards builders who have successfully delivered in the past.

3. Legal & Regulatory Cleanliness – 20% Weight

We evaluate the builder's compliance with RERA and check for open legal disputes:

Status Score Contribution
0 complaints 20 points
1–2 complaints 10 points
3+ complaints 0 points

We only use verified complaints published by regulatory authorities.

4. Public Sentiment – 10% Weight

We consider genuine buyer feedback from digital platforms such as Google or housing portals.

  • We take the Google Star Rating (1.0–5.0)
  • Multiply by 2 to translate into a maximum of 10 points

To prevent manipulation: Ratings with fewer than 10 reviews are proportionally discounted.

This ensures fair representation of real customer experience.

Kill Switch: Safety Override

Certain conditions immediately set the builder's Trust Score to 0, regardless of other metrics:

This automatic override protects customers from high-risk developers.

Formula Transparency

Trust Score (0–100) =

Delivery Score max 40

+

Experience Score max 30

+

Legal Cleanliness Score max 20

+

Sentiment Score max 10


(capped at 100)
(or 0 if builder is flagged in the Kill Switch)

This formula is applied uniformly to all builders.

Verified Data Sources

To ensure accuracy, every component of the score is backed by verifiable data, including:

State RERA websites (complaints, project status)
BBMP / BDA / BMRDA records
SLR/Drone mapping data for land disputes
Google public reviews
Builder documents: OC, CC, sanction plans, title deeds
Construction timeliness evidence

All inputs are timestamped, logged, and audited monthly.

Monthly Audit & Continuous Monitoring

Trust Scores are refreshed every 30 days using:

If any risk indicators appear (spike in complaints, large delay, sudden rating manipulation), the builder is flagged for manual review.

Full Transparency for Customers

Every Builder Profile displays:

  • Trust Score (0–100)
  • Color Shield Category (Platinum / Gold / Verified / Caution)
  • Score Breakdown:
    • • Timeliness: X/40
    • • Experience: Y/30
    • • Legal: Z/20
    • • Sentiment: S/10
  • Last Audit Date
  • Docs Verified status
  • RERA Status
  • Dispute history (if any)

This allows buyers to understand exactly why the score is what it is.

Why This Methodology Builds Trust

Transparent

Every point is traceable and explained.

Auditable

Based on verifiable public and regulatory data.

Fair

All builders evaluated using the same rules.

Buyer-centric

We prioritize what matters most—timely delivery and legal cleanliness.

Hard to manipulate

Review count discounting, kill switch, and monthly audits prevent gaming.

Evidence-based

Built on data, not advertising influence.

Homebuyers can rely on the Trust Score because it is built on evidence, not advertising influence.
