Let’s create a custom Redfin scrapers for each one.
Environment Setup for Redfin Scraping
The first thing to setup a custom Redfin scraper is ensuring all required libraries are installed so lets go ahead.
Python Setup: Begin by confirming whether Python is installed on your system. Open your terminal or command prompt and enter the following command to check the Python version:
1 | python --version |
If Python is not installed, download the latest version from the official Python website and follow the installation instructions provided.
Creating Environment: For managing project dependencies and ensuring consistency, it’s recommended to create a virtual environment. Navigate to your project directory in the terminal and execute the following command to create a virtual environment named redfin_env:
1 | python -m venv redfin_env |
Activate the virtual environment by running the appropriate command based on your operating system:
On Windows:
1
redfin_env\Scripts\activate
On macOS/Linux:
1
source redfin_env/bin/activate
Installing Libraries: With your virtual environment activated, install the required Python libraries for web scraping. Execute the following commands to install the requests and beautifulsoup4 libraries:
1 | pip install requests |
Choosing IDE: Selecting a suitable Integrated Development Environment (IDE) is crucial for efficient coding. Consider popular options such as PyCharm, Visual Studio Code, or Jupyter Notebook. Install your preferred IDE and ensure it’s configured to work with Python.
Once your environment is ready, you’ll be all set to use Python to scrape Redfin’s big collection of real estate data.
How to Scrape Redfin Property Pages
When it comes to scraping Redfin property pages, there are two main types to focus on: rental property pages and sales property pages. Let’s break down each one:
Scrape Redfin Rental Property Pages
Scraping rental property pages from Redfin involves utilizing a private API employed by the website. To initiate this process, follow these steps:
- Identify Property Page for Rent: Navigate to any property page on Redfin that is available for rent. For example this.
- Access Browser Developer Tools: Open the browser’s developer tools by pressing the F12 key and navigate to the Network tab.
- Filter Requests: Filter requests by selecting Fetch/XHR requests.
- Reload the Page: Refresh the page to observe the requests sent from the browser to the server.
Among the requests, focus on identifying the floorPlans request, which contains the relevant property data. This request is typically sent to a specific API URL, such as:
1 | https://www.redfin.com/stingray/api/v1/rentals/rental_id/floorPlans |
The rental_id in the API URL represents the unique identifier for the rental property. To extract this data programmatically, Python can be used along with libraries like requests and BeautifulSoup. Below is a simplified example demonstrating how to scrape rental property pages using Python:
1 | import requests |
In this example, the scrape_rental_property function extracts the rental ID from the HTML of the property page and constructs the corresponding API URL. Subsequently, it sends a request to the API URL to retrieve the property data in JSON format.
Example Output:
1 | { |
Scrape Redfin Sales Property Pages
Scraping sales property pages using redfin scraper involves using XPath and CSS selectors as there’s no dedicated API for fetching the data. Below is a simplified example demonstrating how to scrape redfin sales property pages using Python with the requests and BeautifulSoup libraries:
1 | import requests |
In this example, the parse_property_for_sale function extracts property data from the HTML content of sales property pages using BeautifulSoup and returns it as a JSON object. Then, the scrape_property_for_sale function iterates over a list of property page URLs, retrieves their HTML content using requests, and parses the data using the parse_property_for_sale function.
Example Output:
1 | Scraped 2 property listings for sale |
How to Scrape Redfin Search Pages
When you want to scrape redfin data from it’s search pages, you can do so by tapping into their private search API, which provides the information you need in JSON format. Here’s how you can find and access this API:
- Go to any search page on redfin.com.
- Press the F12 key to open the browser developer tools and peek into the page’s HTML.
- Search for the location (e.g. Los Angeles).
- Search for the API which meets your expectations in the network tab.
By following these steps, you’ll find the API request responsible for fetching data related to your specified search area. To locate this API, head over to the network tab and filter the requests by Fetch/XHR.
To actually scrape Redfin search results, you’ll need to grab the API URL from the recorded requests and use it to retrieve all the search data in JSON format. Here’s a simple Python script to help you do that:
1 | import requests |
In this script, the scrape_search function sends a request to the search API URL and then extracts the relevant JSON data from the API response. Executing this code provides us with property data retrieved from all pagination pages of the search results.

1 | <url> |
Note: The timezone used in these sitemaps is UTC-8, as indicated by the last number in the datetime string.
Implementing Redfin Feed Scraper in Python
To scrape these Redfin feeds and retrieve the URLs and timestamps of the recent property listings, you can use Python along with the requests library. Here’s a Python script to help you achieve this:
1 | import requests |
Running this script will provide you with the URLs and dates of the recently added property listings on Redfin. Once you have this information, you can further utilize your Redfin scraper to extract property datasets from these URLs.
Example Output:
1 | { |
