Problem

Rental research required too much manual checking across listing sources, spreadsheets, and pricing notes.

Solution

Built a workflow that collects listing data, normalizes key fields, stores structured results in Google Sheets, and uses OpenAI to classify listings as Good, Average, or Overpriced.

Impact

Improved property review speed, reduced manual analysis, and created a repeatable AI-assisted decision system.

  3. 03

    Design the automation

    Build and test
