The AlphaScore is a 15-pillar composite that turns a Bengaluru property into a defensible buyer-side verdict. This is the transparent, deployed methodology as of Feb 2026. It's meant to be read, argued with, and improved on.
The 15 pillars
1. Corridor ₹/sqft benchmark
Weight: 12%
2. Unit-level premium/discount
Weight: 8%
3. Builder credibility index
Weight: 10%
4. RERA phase compliance
Weight: 8%
5. Title + EC integrity
Weight: 9%
6. Khata + BBMP compliance
Weight: 6%
7. Water reality (Cauvery/borewell)
Weight: 8%
8. Commute (MG Road + IT hub)
Weight: 6%
9. Schools + amenities within 3km
Weight: 5%
10. Rental yield / resale liquidity
Weight: 6%
11. Loan LTV + sanction friction
Weight: 4%
12. OC + completion readiness
Weight: 5%
13. Ambient risk (litigation, dispute)
Weight: 6%
14. Infra pipeline (metro / STRR)
Weight: 4%
15. Micro-climate (traffic, flood)
Weight: 3%
Why these weights
Pillar weights reflect what actually drives buyer regret in the 12-24 months after keys. Legal (5+6) totals 15% because a title flag makes every other pillar irrelevant. Water (7) totals 8% because water reality drives resale liquidity independently of corridor rate. Infra pipeline (14) is low-weighted because most 'metro extension' timelines slip by 30-40%, and we refuse to weight buyer decisions on aspirational infrastructure.
The safety-over-score override
Any red flag on Pillars 4, 5, 6, 12 overrides the composite. Even if the property scores 82/100 across the other 11 pillars, an undischarged mortgage on EC (pillar 5) freezes the verdict to WAIT until it clears. Score is a summary — safety is a gate.
What we're changing in the next version
- Adding a corridor-water-tier band (A/B/C) as a hard gate on Pillar 7.
- Introducing a builder-cluster credibility index for micro-builders.
- Widening the ambient-risk source list to include Karnataka HC pending-list.
