Challenge 17 - Housing Market Madness - Solution

0 ×

Housing prices in America are a bit out of control. In this challenge, you will see how housing prices have changed through time. Here are the tasks for this challenge:

1. Read the dataset for this challenge directly from its link, without downloading any files to your local machine with the CSV Reader node.

2. Using monthly data, calculate the yearly data and visualize the 3 RegionNames with the most drastic changes. Note: Consider the year the data was collected until the most recent year to calculate change; feel free to ignore missing values.

3. Find the state (regardless of region) with the lowest prices for homes on average currently.

4. According to Wikipedia, "The bankruptcy of Lehman Brothers on September 15, 2008 was the climax of the subprime mortgage crisis.". What visualizations can show the effect this had on the housing market? We used our answer to question 2 to keep our visualizations clutter-free.
