How to Extract Real Estate Data from Zillow and Realtor.com

Real estate data is one of the most valuable scraping targets. Here's what you can extract and how.

What Data Is Available

• Property listings (address, price, beds, baths, sqft)
• Historical prices and tax assessments
• Neighborhood data (schools, crime, demographics)
• Agent contact information
• Recent sales (comps)

Approach 1: Zillow API (Official)

Zillow deprecated their public API in 2021, but alternatives exist:

• RapidAPI Zillow alternatives — several third-party APIs wrap Zillow data
• Realtor.com API — available through RapidAPI
• Redfin — has public data endpoints

Approach 2: API-First Scraping

Real estate sites load property data via AJAX calls:

// Intercept the data loading request
const browser = await chromium.launch();
const page = await browser.newPage();

const propertyData = [];
page.on('response', async (res) => {
  if (res.url().includes('property') || res.url().includes('listing')) {
    try {
      const json = await res.json();
      propertyData.push(json);
    } catch(e) {}
  }
});

await page.goto('https://www.zillow.com/homes/for_sale/');
// propertyData now has structured listing info

Approach 3: Public Records

Many county assessor websites have public property records APIs:

// Example: county assessor data
const url = 'https://assessor.county.gov/api/parcels?address=123+Main+St';
const data = await fetch(url).then(r => r.json());

Use Cases

1. Investment analysis — find undervalued properties
2. Market research — price trends by neighborhood
3. Lead generation — find FSBO (For Sale By Owner) listings
4. Competitor analysis — track other agents' listings
5. Rental market — compare rental prices across areas
