These expired listings are often forgotten or neglected, even though the property owner may still be interested in relisting. As a result, real estate professionals lose potential revenue and miss opportunities to close deals.\n\n## Solution\nThis automation workflow automatically detects listings that haven't had any activity for over 30 days. It then generates a personalized follow-up email using an AI model like OpenAI (GPT-4), asking the property owner if they would like to relist the property. The system sends this follow-up via email, and optionally updates the listing status based on any replies from the owner.\n\n## For Who\n- Real estate agents  \n- Real estate brokers  \n- Real estate CRM tool developers  \n- Property managers  \n- Real estate marketing teams  \n- Listing management agencies  \n\n## Scope\n- **Source:** Google Sheets (listing data)  \n- **Filter:** Listings with `last_activity` older than 30 days  \n- **Generate:** Personalized reactivation message using OpenAI  \n- **Send:** Follow-up email via Gmail or SMTP  \n- **Optional:** Update listing status in Sheet or CRM when owner replies  \n\n## How to Set Up\n\n1. **Google Sheet**  \n   Create a sheet with these columns:  \n   `title`, `owner_name`, `email`, `property_type`, `location`, `last_activity`\n\n2. **Read Sheet in n8n**  \n   Use **Google Sheets node** to load all listings.\n\n3. **Filter Listings**  \n   Use a **Set + IF node** or **Code node** to keep only rows where `last_activity` is more than 30 days ago.\n\n4. **Generate Email with AI**  \n   Use **OpenAI node** to generate a follow-up email for each expired listing.\n\n5. **Send Email**  \n   Use **Gmail or SMTP node** to send the generated email to the owner.\n\n6. **(Optional) Update Status**  \n   After email is sent, update the listing\u2019s status to `followed_up` in the sheet.\n\n---\n"
