We worked with the Sightline Institute to map every residential home sale in the City of Seattle over the 12 month period starting July 1st, 2016. By analyzing price differences between single-family and multi-family homes sold both citywide and within each of Seattle's 77 neighborhoods, we were able to show that single-family homes cost 42 percent more than multi-family homes. We used Carto to build an interactive web map showing the average sale price for single-family and multi-family homes by neighborhood, as well as every individual sale. We will explain how we used data from the King County Assessor to analyze and map the home sales, and provide a step-by-step explanation of how we imported our data to Carto, stylized the map, and added functionality and custom legends.
