Zillow Real Estate Scraper

Features

Our free Zillow Real Estate Scraper lets you extract data from real estate listings on Zillow.com. It enables you to search properties in any location and extract detailed information, such as full addresses, longitude, latitude, price, description, URL, photos, number of bedrooms and bathrooms, and all other information available.

Why scrape Zillow?

Zillow has over 110 million properties in its database, more than 245 million monthly unique visitors, and 80% of all homes in the United States have been viewed on the website.

So what could you do with all that real estate listings data?

  • Use the data to add value to your real estate business by providing extra information to your visitors.
  • Extract business intelligence to predict the future of the real estate market, track demographic changes, and identify popular new neighborhoods.
  • Make smarter investment decisions by ensuring that you understand how the market is changing.
  • Automate real estate agency lead generation and make sure that you can find, and keep, the right clients in the long term.
  • Find new ways to provide tech services to real estate agencies and local listings agencies.
  • Train AI models to predict future trends and act fast when opportuities arise.

These are just some ideas to get you thinking about how web scraping can give you the data you need. Check out our dedicated Real Estate page for more inspiration.

What about the Zillow API?

Zillow has a great API, but it does impose some restrictions on users, such as the number of API calls per page at the same time. This scraper actually uses the Zillow API, but it recursively splits the map four ways to overcome the limits per search. To limit the number of results, you can set the maximum depth of the four-way split zooms. This is done using the maxLevel attribute.

Cost of usage

The average cost of using the Zillow Scraper is about $0.25 for every 2,000 results scraped.

Note that it is much more efficient to run one longer scrape (at least one minute) than more shorter ones because of the startup time.

Input

Field Type Description Default value
search string Query string to be searched "Los Angeles"
startUrls array List of request objects that will be deeply crawled. The URL can be any Zillow.com home listing page. none
maxItems number Maximum number of pages that will be scraped 200
maxLevel number Maximum map splitting level 20
minDate string Minimum date of the results allowed (timestamp or date string) none
simple boolean Toggle whether simplified results will be returned true
extendOutputFunction string Function that takes Zillow home data object as argument and returns data that will be merged with the default output. More information in Extend output function async ({ item, data }) => { return item; }
extendScraperFunction string Allows you to add additional functionality to the scraper. More details in Extend scraper function async ({ item, data, customData, Apify }) => { }
proxyConfiguration object Proxy settings of the run. If you have access to Apify proxy, leave the default settings. If not, you can set { "useApifyProxy": false" } to disable proxy usage { "useApifyProxy": true }

Either the search or startUrls atrribute has to be set.

Output

Output is stored in a dataset. Each item is information about a property home. If the simple attribute is set, an example result may look like this:

{
  "address": {
    "streetAddress": "20349 Valerio St",
    "city": "Winnetka",
    "state": "CA",
    "zipcode": "91306",
    "neighborhood": null,
    "community": null,
    "subdivision": null
  },
  "bedrooms": 4,
  "bathrooms": 3,

}

If the simple attribute is not set, the result will contain many more attributes. You can find an example of a full result here.

Map splitting

To overcome the Zillow API limits of 1,000 calls per day and 20 calls per page, the scraper uses Zillow's internal API to search for homes on a rectangular section of a map.

Note that the limit at the time of creating this actor was 500 results per page, so the calculations below are based on that figure.

If the number of results on the map is higher than 500, the map is split into four quadrants and zoomed. Each of these quadrants is searched for homes and can again contain 500 results (that means using 1 split, we've increased the total result limit to 2,000). Unless the result count in the quadrant is less than 500 (no need to split anymore), the quadrant is split again and so on. To limit this behavior, you can set the maxLevel attribute. That way, the map will be split only a maximum of maxLevel times, even if the number of results is higher than 500.

Extend output function

You can use this function to update the default output of this actor. This function gets Zillow internal home data object as an argument, so you can choose which other attributes you would like to add. The output from this function will get merged with the default output.

The internal home object contains huge amounts of data - here's an example.

Any of these attributes can be added to the result object.

The return value of this function has to be an object!

You can use this function to achieve three different things:

  • Add a new field - Return object with a field that is not in the default output
  • Change a field - Return an existing field with a new value
  • Remove a field - Return an existing field with a value undefined
async ({ item, data }) => {
  if (!data.schools || !data.schools.length) {
    return null; // omit output
  }

  item.schools = data.schools; // add new array data
  item.photos = undefined; // remove the photos array from the output, making it CSV friendly
  delete item.photos; // works as well

  return item; // need to return the item here, otherwise your dataset willbe empty
}

This example will add a new field schools, remove the photos field, and omit the output if there's no schools information

Extend Scraper function

You can add additional functionality directly inside the handlePageFunction of the scraper without modifying the existing code. This function receives internal functions that can be used to enqueue, fetch, or control the scraper.

async ({ state, request, requestQueue, Apify, LABELS, TYPES, processZpids, queryRegionHomes, customData }) => {
    // returning something here is no-op
    if (request.userData.label === LABELS.INITIAL) {
        await requestQueue.addRequest({
            url: customData.zillowUrl,
            userData: {
                label: LABELS.DETAIL,
            }
        })
    }
}
