Context

20+ Years of King County, Washington (Seattle Area) home sales data

Content

This data included a variety of home attributes, geo-locational and property change data that I've collected this data over the past decade. The use of historical data together with current data in the cleaning and preparation allows for more precise identification of changes such as remodels, tear-down and new construction. For a more complete view of what the preparation process does see: https://github.com/andykrause/kingCoData.

These data are developed for the purpose of developing predictive home price models and housing price indexes.
