How to Scrape Zillow for Real Estate Listings using Python and LXML

Web Scraping real estate data is a viable option to keep track of real estate listings available for sellers and agents. Being in possession of extracted real estate information from real estate sites such as Zillow.com can help adjust prices of listings on your site or help you create a database for your business. In this tutorial, we will scrape Zillow data using python, and show you how to extract real estate data. In particular, we will show you how to scrape real estate listings based on zip code.

Here are the steps to scrape Zillow

  1. Construct the URL of the search results page from Zillow. Example – https://www.zillow.com/homes/02126_rb/
  2. Download HTML of the search result page using Python Requests.
  3. Parse the page using LXML – LXML lets you navigate the HTML Tree Structure using Xpaths.
  4. Save the data to a CSV file.

Packages

For this web scraping tutorial using Python 3, we will need some packages for downloading and parsing the HTML. Below are the package requirements:

The Code

We have to first construct the search result page URL. We’ll have to create this URL manually to scrape results from that page. For example, here is the one for Boston- https://www.zillow.com/homes/02126_rb/.

You can download the code from the link here https://gist.github.com/scrapehero/5f51f344d68cf2c022eb2d23a2f1cf95  if the embed does not work.

Running the Zillow Scraper

Assume the script is named, zillow.py. When you type in the script name in a command prompt or terminal with a -h

usage: zillow.py [-h] zipcode sort

positional arguments:

  zipcode

  sort      
                available sort orders are :

                newest : Latest property details

                cheapest : Properties with cheapest price

optional arguments:

  -h, --help  show this help message and exit

You must run the zillow scraper using python with arguments for zip code and sort. The sort argument has the options ‘newest’ and ‘cheapest’ listings available. As an example, to find the listings of the newest properties up for sale in Boston, Massachusetts we would run the script as:

python3 zillow.py 02126 newest

This will create a CSV file called properties-02126.csv that will be in the same folder as the script. Here is some sample data extracted from Zillow.com for the command above.

    I just tried this script. It looks like zillow implemented a Captcha to prevent automated harvesting of their data. Here is a snippet from the response I got:

    response = get_response(url)

    ….function handleCaptcha(response)….

    Yes, I am receiving the same error message. It appears to stem from the variable “raw_json_data” being empty. Maybe a problem with the parser.xpath() call?

I ended up installing tesseract to handle Captcha’s and reran zillow.py. Still no luck

Follow the advice of “Xiyu-1 commented on Mar 7” from the git site “https://gist.github.com/scrapehero/5f51f344d68cf2c022eb2d23a2f1cf95”

Here Xiyu describes how the script needs to be modified to return the results and complete creation of the csv file.

Cheers,
