This post is looking into seasonal inventory of housing in west LA. I’m using data from the Trulia api. The data is from 2010 to the present. I’m also using this post to learn how to use a Shiny app.


The top plot shows number of listings by month, the middle plot is the 6 month smoothed average trend, and the bottom plot is the seasonal component.



Couple quick takeaways:

  • Inventory has decreased tremendously since 2010.
  • The seasonal component suggests inventory is highest in the late summer/fall and drops sharply towards new years.
  • Shiny is very easy to learn; I had the app up and running in a couple hours.
