The Complete Guide to Real Estate Web Scraping in 2026

Real estate is one of the most competitive data markets. Here's how to do it right.

Why Scrape Real Estate?

Price monitoring — Track listing prices, drops, trends
Market analysis — Compare neighborhoods, cities, regions
Investment research — Identify undervalued properties
Competitive intelligence — Watch what other agents/brokers list

Major Platforms

Platform	Difficulty	Anti-Bot	Data Quality
Zillow	Hard	Cloudflare	Excellent
Realtor.com	Medium	Rate limits	Excellent
Redfin	Hard	JS rendering	Very Good
Rightmove (UK)	Easy	Basic	Good

Key Data Points

Price, address, bedrooms/bathrooms, sqft
Listing date, days on market
Price history (if available)
Tax assessment, HOA fees
Nearby schools, crime stats

Avoiding Common Pitfalls

IP Blocking: Real estate platforms are aggressive. Use residential proxies.

Data Accuracy: Some platforms hide data behind lazy loading. Ensure JS rendering.

Legal: Public listings are public information. Respect robots.txt and rate limits.

Sample Extraction

const result = await fetch('https://run.xcrawl.com/v1/ai-extract', {
  method: 'POST',
  headers: { 'X-API-Key': 'your-key' },
  body: JSON.stringify({
    url: 'https://www.zillow.com/homedetails/...',
    schema: {
      price: 'Current listing price',
      address: 'Street address',
      beds: 'Number of bedrooms',
      baths: 'Number of bathrooms',
      sqft: 'Square footage'
    }
  })
});
