With the growth of the U.S. since the Great Recession in 2008, almost all U.S. sale prices are increasing. But still, there exist people who need to buy houses even though the price is increasing. Where is an appropriate place to invest in real estate? In order to come up with a solution, I visualized the growth rate of U.S. house sales price over 10 years in this visualization. This bar chart visualizes the U.S. top 10 U.S. cities with the highest house price growth rate in approximately a ten-year trend. This visualization is a somewhat upgraded analysis based on the first map. Please notice that this bar chart measures the sales price growth rate in ten years, instead of the sales price difference in the first map visualization. The formula of calculating the growth rate can be found in my "Data&Processing" section.
Nothing needs to be interactive in this graph since it will not help make this visualization more informative at this point. Less is more!
We can’t tell which exact city is the most valuable one to invest in the future, but I can see which city was more valuable to invest in the past. And I even can specify it to which year was a good time or not. With this information, we can make some prefictions by learning from the past and invest in the future.
Moreover, I could directly visualize that from the dataset Zillow provides, all of these top ranked cities have exceed a 100% of the growth rate. In the city we all live, San Francisco have a tremendous house price growth rate over these years. At the first glance, this phenomenon can probably indicate that the price of good and service increases. But from the other perspective, it might not be a bad news. To some extent, it means that the U.S. economy has developed pretty well, especially if the user take a look at the east and west coast. This also means that people's life standard have been improved through time.
