⚙️ How It Works

The Real Estate Property Scraper accepts one or more search locations and drives a real headless Chromium browser through Redfin's homepage and search flow for each one. While the browser navigates, the Actor listens for Redfin's internal api/gis network responses and captures the raw listing payload directly — the most complete source of Real Estate Property data. If no network data is intercepted, the Actor falls back to parsing visible listing cards from the rendered page DOM using a combination of CSS selectors and text-pattern matching for price, address, beds, baths, and square footage. All collected Real Estate Property records across every location are pushed to the Apify Dataset in a single batch at the end of the run.

Key Processing Steps:

1. Input Parsing – Accept one or more search locations and a maximum item cap
2. Proxy Setup – Configure Apify residential proxy and pass credentials into Playwright
3. Browser Launch – Start headless Chromium with anti-automation-detection flags and script injection
4. Location Loop – Iterate through each requested Real Estate Property search location
5. Homepage Warm-Up – Navigate to Redfin's homepage first to establish session cookies
6. UI Search – Fill the search box, select a suggestion, and submit the Real Estate Property search
7. Network Interception – Capture and parse api/gis JSON responses as they stream in
8. Auto-Scroll – Scroll the results page to trigger additional card rendering
9. DOM Fallback Parsing – Extract listing details directly from rendered cards if no network data was captured
10. Deduplication – Remove duplicate Real Estate Property listings by URL
11. Result Capping – Stop collecting once maxItems is reached for a location
12. Dataset Push – Push all collected records from every location in a single batch

Key Benefits:

• Pull Real Estate Property listings for any location without manual searches
• Capture rich, structured listing data straight from Redfin's own API responses
• Fall back gracefully to visible page data when the network layer changes
• Feed market-analysis dashboards, research pipelines, or investment tools
• Automate recurring Real Estate Property checks as new listings appear

• Scales with the number of locations searched and maxItems requested

Resource Usage

⚠️ Important Notes

Legal & Compliance

• Fair Use: Respects Redfin's public search interface and applies pacing delays between requests
• Public Data Only: Retrieves only publicly visible Real Estate Property listing data
• Terms of Service: Automated collection may be subject to Redfin's Terms of Service — review before large-scale or commercial use
• Legal: Not legal, financial, or investment advice — consult qualified professionals before acting on this data

Data Quality

• Freshness: Reflects Redfin's live listings at time of run
• Completeness: DOM fallback parsing may return "N/A" for fields not visible on the page
• Accuracy: Network-intercepted data is generally more complete and accurate than DOM-fallback data
• Verification: Cross-check high-stakes figures (price, availability) against the live Redfin website

Best Practices

• Always configure a residential proxy for the most reliable Real Estate Property search access
• Use specific, well-formatted locations (e.g., "City, ST" or ZIP code) for the most reliable search matches
• Keep maxItems reasonable per location to control run time and resource usage
• Re-run periodically to track new listings or price changes
• Expect some fields to read "N/A" when a run falls back to DOM parsing
