I have seem some related questions but none of them seem to have the answer I am looking for. I want to be able to find a website (say like the Multiple Listing Service listings) that would allow me to scrape data from their site about property sales records. In particular, for a given zip code I would like to be able to aggregate purchase histories such as number of houses sold in a particular month and year, and prices (during that month and year) in which the houses sold. Does a website with this type of data to be collected exist?

  • Does it have to be a website? Scraping sites will often be in violation of copyright (That does not make your question invalid here, but it may not be the wise thing to do).

You are looking for the property appraiser's office for each county to assemble the data for free. Anything above this level is going to be a cost item.

For example, the Polk County Property Appraiser's office has the Appraisal Data and the GIS Data at the Parcel Level. The Appraisal Data includes the sales database from which to pull your data.

    Great answer. FYI, this dataset might be called the assessor's roll, or the auditor data, or something else depending on the county. Commented Nov 2, 2016 at 18:54

Daniel Miller's answer recommending property appraiser's offices is great, and if your need is confined to a couple of counties, it's not too much work to locate each dataset. However, if you need this information on a nationwide basis, hunting down every single appraiser's data is incredibly tedious.

An alternative is something like the Zillow API. Zillow has real estate data for the entirety of the U.S., and in my experience it's pretty solid data. They have rate-limits and terms of use limiting what you can do with their API, but their data is very good (and is usually sourced from those property appraisers).

  • Thanks Hayden, I keep forgetting about the Zillow API as it is a commercial source. It is a great resource. Commented Nov 3, 2016 at 1:59
