Limitations

1. Terms of Service: Web scraping Redfin technically violates their ToS. Use responsibly.
2. Rate Limiting: Redfin may block IP addresses that make too many requests. The scraper includes delays to mitigate this.
3. Dynamic Content: Site structure changes may occasionally break the scraper.
4. No Guarantee: This is an unofficial method with no uptime guarantees.
5. Filters: Price/bed/bath filters work best with zipcode-based searches. City name searches may return limited results.
6. Use Zipcodes: For reliable results, always use zipcodes (e.g., "78701") instead of city names.

Error Handling

• Check internet connection
• Redfin may be blocking requests (wait and retry)
• Site structure may have changed (may need script updates)
• Verify location format is valid

Best Practices

1. Add delays between requests (built into script)
2. Don't make excessive queries in short time period
3. Use specific locations rather than broad searches
4. Filter results server-side with parameters when possible
