Seattle Housing Market

Prices by Dynamic ZIP Code

This project explores how housing prices vary across Seattle ZIP codes and what geographic patterns influence property values. Using publicly available housing data and spatial visualization, the analysis highlights where the city’s highest-priced areas are located and examines the key drivers behind those differences.

  • Data sources
    Data came from the Zillow website and a private dataset from Johnson & Wales University.
  • Tools used
    Tableau for spatial visualization and data exploration, with data preparation performed in Excel.
