How I Generated 1,100+ Real Estate Leads for FREE using n8n!

I just created an automation that generated over 1,100 business leads for real estate agencies across the US without spending a single cent on APIs or other services.

What kind of data did I collect?

Each lead includes:
- Business name
- Complete address (city, postal code, street)
- Opening hours
- Website
- Email addresses (in many cases multiple per business)
- Phone numbers (almost 100% coverage)
- Social media accounts (Facebook, Instagram, etc.)

How it works:

I use the free Overpass API combined with a custom n8n automation workflow to:
- Loop through 200+ city-keyword combinations (like "Los Angeles - real estate")
- Query the Overpass API using carefully formatted search parameters
- Extract and clean all business contact data
- Automatically visit each business website to scrape additional email addresses
- Filter out irrelevant results and junk emails
- Save everything directly to Google Sheets

Key features shown in the video:

- Using precisely formatted API queries to maximize results
- Searching by both business name/description AND specific business tags
- Using regex for email extraction from websites
- Customizable filtering system to remove irrelevant leads
- Learning from initial results to improve future queries (replacing "real_estate" with "estate_agent" in tags)

The best part? You can adapt this workflow for ANY type of business in most regions around the world!
