Turning rent data into a household decision

The tracker connects market data to a practical question: which city and apartment size fit a household budget?

My role

Data model, UI concept, visualization, calculation logic and responsive implementation.

Key decisions

  • — One city selection updates trend, ranking and income estimate.
  • — The curated dataset is clearly distinguished from real-time data.
  • — Sources and assumptions are linked directly in the product.

What works technically

  • — Accessible interactive SVG chart
  • — Two household and budget modes
  • — Extracted, tested calculation logic

Next development step

The next step is a versioned import pipeline that validates quarterly data and documents changes.
