I've been learning web scraping recently and wanted to do a project to post on Kaggle. I've searched and can't find anywhere with express permission to web scrape their site. I wanted to scrape their rental data (as the for_sale and sold data are already available in csv files, but rentals aren't). Anyone can link me to permission or something legal, so that I can include it in my project? This world of scraping legality is new to me, so apologies for any ignorances on my part.

Realtor.com and Redfin are taking a stand against crime data being listed on their websites. The real estate companies have removed the data due to growing concerns that it could perpetuate racial inequity.
Redfin.com is one of the biggest real estate websites in the United States making it the biggest public real estate dataset out there. Containing fields like real estate prices, listing locations and sale dates and general property information.
This is valuable information for market analytics, the study of the housing industry, and a general competitor overview. By web scraping Redfin we can easily have access to a major real estate dataset.
See our Scraping Use Cases guide for more.
To start, let's take a look at how to scrape property data from a single listing page. Property pages on redfin.com differ based on whether this property is for sale or rent. Let's begin with scraping redfin.com property pages for rent.
The id that follows the /rentals route represents the rentalId of the property. To scrape this this data within our scraper, we'll mimic this API request by getting the rentalId from the page HTML and then sending a request to the API:
First, we send a request to the property page URL to extract the rentalId from the HTML. Next, we use this ID to define the API URL of each property page. Finally, we send requests to the API URLs we defined to get each property data in JSON.
Here, we define a parse_property_for_sale function. Which parses the property page data from the HTML using XPath and CSS selectors and returns the data as a JSON object. Next, we'll use this function with httpx to scrape the property pages:
Yes. Redfin.com's data is available publically; we're not collecting anything private. Scraping Redfin at slow, respectful rates would fall under the ethical scraping definition.
That being said, attention should be paid to GDRP compliance in the EU when storing personal data such as seller's name, phone number etc. For more, see our Is Web Scraping Legal? article.
Currently, redfin.com doesn't have a public API. However, we have seen that we can use redfin's private APIs to get property listing data.
Redfin also publishes market summary datasets in their data-center section.
Like scraping, we can also crawl redfin.com by following related rental pages listed on every property page. To write a Redfin crawler, see the related properties field in datasets scraped in this tutorial.
In this tutorial, we built a Redfin scraper in Python with a few free community packages. We started by taking a look at how to scrape property pages using redfin's private API and HTML selectors. We also explained how to scrape redfin.com search pages using the search API. Finally, we explained how to find property listings and track new/updated properties on redfin's sitemap system.
For this Redfin data scraper we used Python with httpx and parsel packages. To avoid being blocked, we used ScrapFly's API, which smartly configures every web scraper connection to avoid being blocked.

I have a few posts about this but I have found a new issue. You will notice from link1 and link2 that depending on whether the house is on the market or not the page will have a different way of where the redfin estimate is displayed. I have a way of getting the redfin estimate from link1 but not at link2.
