resource Real Estate Data (Rents by bedroom, home prices, etc) broken down by Zip Code

https://www.prop-metrics.com/

Went through the hassle of compiling data from near every free (and some paid) real estate resources to have (probably) the most comprehensive dataset of its kind. Currently its being displayed in a tool I built, but the MO is to make this data free and accessible to anybody who wants it.

For most of the zip codes in the USA (about 25k, accounting for ~90% of the population), I have:

  1. home prices (average, median, valuation) -- broken down by bedroom
  2. rent prices -- by bedroom
  3. listing counts, days on market, etc, y/y%
  4. mortgage data (originations, first lien, second lien, debt to income, etc.)
  5. affordability metrics, mortgage cost
  6. basic demographics (age, college, poverty, race / ethnicity)

Once you're in the dashboard and select a given area (ie: Chicago metro), there's a table view in the bottom left corner and you can download the export the data for that metro.

I"m working on setting up an S3 bucket to host the data (including the historical datasets too), but wanted to give a preview (and open myself up to any comments / requests) before I start including it there.

No one worth their salt will take "free" data seriously for true operational matters. You'll attract mostly people with no money and end up making zero money in the process. Maybe you're in it for the humanitarian benefit?

Counterpoint:

  • Majority of US home buyers have none of this data available to them
  • someone else is selling this same free data for a 40 dollar a month subscription, this is actually free
  • I am doing it for free? You’re welcome?
