Advanced Anti-Scraping Measures: Property websites use technologies like JavaScript, AJAX, and CAPTCHA to deter scraping. These measures can hinder data collection and lead to IP blocks, necessitating specific bypassing techniques.
Questionable Data Quality: The dynamic nature of property prices introduces the risk of obtaining outdated information that aligns differently from the current real estate market conditions.
Copyrighted Data: Web scraping's legality, especially for real estate websites, remains a debated topic. The general guideline is to scrape publicly available data while respecting copyright rules. Legal advice can ensure compliance with relevant regulations and avoid potential breaches.
