AI Telegram Bot for Real Estate Lead Qualification (n8n + OpenAI)

A complete n8n automation for real estate companies: an AI agent on Telegram that chats with buyers in Egyptian Arabic or English, collects their requirements, scores how serious they are, and saves qualified leads to Google Sheets automatically for the sales team.

How it works:

1. Telegram Trigger receives the client's message.

2. An AI Agent (OpenAI) with conversation memory (last 15 messages), so it never repeats a question.

3. A custom prompt makes the bot ask one question at a time and collect 10 details: property type, location, budget, payment method, timeline, purpose, name, phone, email and extra requirements.

4. A points-based scoring system: above 50 points = Qualified, 50 or below = Nurturing.

5. Qualified leads are added or updated in Google Sheets automatically.

6. Guardrails stop the bot from inventing properties, repeating questions or revealing the score to the client.

Result: instant 24/7 replies, automatic filtering of serious buyers, and zero manual data entry.
