Automating Real-Time Property Data Aggregation for Real Estate Investment

Challenge

Josh Cohen, a real estate investor specializing in rapid-turnaround acquisitions, faced bottlenecks in identifying and analyzing newly listed properties across competitive markets. Manual scraping of Zillow listings was slow, error-prone, and unable to scale across multiple cities, resulting in:

Missed opportunities: Delays in accessing listings >24 hours old allowed competitors to act first.
Inconsistent data: Human errors in recording sale prices, square footage, or Zestimates skewed investment analysis.
Scalability limits: Manually processing 100+ cities was impractical, restricting portfolio diversification.

Josh required a scalable, real-time solution to extract and organize Zillow data instantly, enabling agile decision-making in fast-moving markets.

Solution

BlocBelt designed a UiPath-powered web scraper to automate Zillow data extraction with precision and speed. Key features included:

Real-time listing capture: Extraction of properties listed within the last 24 hours to prioritize fresh opportunities.
Multi-city scalability: Parallel processing of up to 100 cities in a single run, with dynamic city input support.
Comprehensive data fields: Automated capture of address, sale price, square footage, Zestimate, bedrooms, bathrooms, listing date, and property type.
Error resilience: Handling of missing data, website layout changes, and connectivity issues to ensure uninterrupted workflows.
Structured output: Auto-organization of scraped data into Excel/CSV files, formatted for immediate analysis.

The solution leveraged UiPath’s advanced selectors and OCR capabilities to navigate Zillow’s dynamic interface without triggering anti-bot defenses.
