Case Study

How Agentic AI Built the Verification Layer for Philippine Real Estate

192,874 records. 25,264 brokers. 8,240 LTS. Free public service.

The Challenge

Philippine real estate data existed. Access didn't.

  • •Zonal values: Buried in BIR Excel files, organized by RDO
  • •Brokers: One-by-one lookup on PRC
  • •LTS: Slow, legacy DHSUD interface
  • •Alternatives: Clunky tools flooded with ads

No unified platform. No modern access. No public infrastructure.

The Solution

I built Ren.ph: a unified verification platform.

Data Sources Integrated

  • • BIR (zonal values)
  • • PRC (broker licenses)
  • • DHSUD (License to Sell)

Features

  • • Instant search across all data
  • • Working calculators
  • • Legal templates
  • • Training academy

The System (High Level)

Multiple AI agents working as a coordinated system:

1

Architect Agent

Orchestrates the workflow

2

Research Agent

Gathers data from sources

3

Normalizer Agent

Structures and standardizes

4

Validator Agent

Cross-checks accuracy

5

Publisher Agent

Deploys to production

Each agent hands off to the next. Errors get caught. Quality stays consistent. This is Algorithmic Integrity in action.

The Result

Live platform serving Filipino real estate buyers, sellers, and professionals.
