Housing Data Provided by Zillow

Updated: 2023-02-01

This dataset contains several configs produced based on files available at https://www.zillow.com/research/data/.

Viewer Notes

Because this repository includes the code used to process the raw Zillow data, the dataset viewer is not enabled. This is because the dataset viewer is not enabled for datasets that run arbitrary python code. For a normal viewer experience, please see the simplified version of this dataset at https://huggingface.co/datasets/misikoff/zillow-viewer. The viewer should be enabled there and the config files should match what is found here.

Supported configs:

  • days_on_market: Days to pending, days to close, share of listings with a price cut, and price cuts.
  • for_sale_listings: Median listing price, new listings, and new pending listings.
  • home_values: Zillow Home Value Index (ZHVI) for all homes, mid-tier, bottom-tier, and top-tier homes.
  • home_values_forecasts: Zillow Home Value Forecast (ZHVF) for all homes, mid-tier, bottom-tier, and top-tier homes.
  • new_construction: Median sale price, median sale price per square foot, and sales count.
  • rentals: Zillow Observed Rent Index (ZORI) for all homes, mid-tier, bottom-tier, and top-tier homes.
  • sales: Median sale price, median sale price per square foot, and sales count.

DAYS ON MARKET AND PRICE CUTS

Days to Pending: How long it takes homes in a region to change to pending status on Zillow.com after first being shown as for sale. The reported figure indicates the number of days (mean or median) that it took for homes that went pending during the week being reported, to go pending. This differs from the old “Days on Zillow” metric in that it excludes the in-contract period before a home sells. Days to Close (mean/median): Number of days between the listing going pending and the sale date. Share of Listings With a Price Cut: The number of unique properties with a list price at the end of the month that’s less than the list price at the beginning of the month, divided by the number of unique properties with an active listing at some point during the month. Price Cuts: The mean and median price cut for listings in a given region during a given time period, expressed as both dollars ($) and as a percentage (%) of list price.
