AI Voice Agent for Real Estate Lead Booking
An AI-powered phone receptionist built for real estate agencies that answers inbound calls, qualifies leads in real time, and books showings directly to Google Calendar — all within the call itself, with no manual follow-up required.
The problem: Real estate agencies routinely lose leads to missed calls — after-hours inquiries, calls during showings, or overflow during busy periods. A slow callback often means the lead has already moved on to a competitor.
What it does:
Answers every call instantly, 24/7
Naturally qualifies the caller (buy/sell intent, area of interest, showing vs. agent call)
Collects contact details and preferred timing conversationally
Checks real-time calendar availability before booking
Prevents double-bookings and duplicate entries automatically
Confirms the appointment out loud before ending the call
Built with: Retell AI (conversational voice layer), n8n (workflow automation and business logic), Google Calendar API (scheduling)
Available for: Custom builds for real estate agencies, brokerages, or property management companies looking to stop losing leads to missed calls

Beautiful workflow by the way. My nicheeee
thanks a lot man its good to know
You are welcome
The after-hours gap is exactly where a narrow pilot can prove itself: capture buy/sell intent, area, and showing window, then re-check calendar availability before confirming. I’d keep a human fallback for unusual requests and log every abandoned call so the brokerage can...
yeah i was planing to upgrade it so it can work more smartly on the edge cases as well and thanks a lot for your opinion it worth a lot

Experimented a bit today with Krea and image generation for a case study I’m putting together around AI EarPods connected to OpenAI.
The focus has been on creating fashion-forward product imagery and art directing a world that feels specific to the identity, rather than just generating nice-looking AI images.
The trickiest part has been product consistency. Especially getting the EarPods to actually sit snug in the ear. If you’ve worked through this process, you probably know the struggle 😅
Simply telling AI to “make it fit more snug or in the ear” doesn’t always work. It loves to reinterpret the product every time.
Still experimenting, but getting closer. If anyone has found a good workflow for keeping products consistent across AI-generated shoots, I’d love to hear it!

🛠️ Show & Tell: AI Voice Receptionist — Retell AI + n8n + Google Sheets + Retool
Hey Contra community 👋
Just wrapped a full AI voice receptionist build for a home services client and wanted to share what went into it.
What it does:
Answers inbound calls 24/7 using Retell AI
Runs 3 real-time checks via n8n: service area · slot availability · customer lookup
Books the appointment live on the call — no double-booking
Logs to Google Sheets and fires a confirmation email automatically
Full Retool command center for the client to manage everything
The tricky part:
Retell AI has a toggle called "Payload: args only" — when enabled, it strips the parent wrapper from the webhook payload. Took a solid debug session to figure out why n8n kept returning empty data. Once I caught it and rebuilt the payload mapping, everything worked end to end.
Stack: Retell AI · n8n · Google Sheets · Retool MCP
Happy to answer questions on any part of the build — webhooks, n8n sub-workflow structure, Retool dashboard setup, whatever.
If you're a builder who gets overflow work in voice AI or home services automation, let's connect 🤝
Nice systems thinking in this build—the handoff between voice intake, availability checks, booking, and confirmation is clearly mapped to a real user outcome. The Retool command center also makes the automation legible instead of hiding it behind the scenes.
Built an AI Voice Agent for Real Estate Lead Qualification 🏡📞
Designed and deployed an end-to-end AI voice agent that handles inbound property inquiries — qualifies leads conversationally, checks calendar availability, and books site visits, no human agent required for the first touchpoint.
How it works:
🎙️ Retell AI powers natural conversation — understands property type, budget, location, and timeline preferences just by talking
🔀 n8n orchestrates everything behind the scenes — routes each call by outcome (Booked / Warm Follow-up / Not a Fit / Incomplete)
📅 Auto-books confirmed site visits directly to Google Calendar
📊 Logs every lead to Google Sheets for tracking
🔔 Sends real-time Telegram alerts to the sales team the moment a lead is qualified
The result: faster response times, zero missed leads outside business hours, and a sales team that only spends time on calls that are actually ready to convert.
Built end-to-end — call flow design, calendar/CRM integration, and automated follow-up logic.
