How to Build a Real Estate AI Voice Agent That Can Handle Thousands of Calls

Real estate agents spend countless hours on the phone — answering inbound property inquiries, making outbound sales calls, and following up with potential buyers.

What if all of that could be handled by a 24/7 AI voice agent that speaks naturally, follows a script, adapts to the conversation, and even sends property listings by email or text?

In this breakdown, I’ll show you exactly how I built a real estate AI voice assistant using the VOHO platform — from prompt creation to a live call demo.

Step 1: Defining the Prompt

In AI voice agents, the prompt is everything. Just like learning a programming language, you have to learn how to “talk” to the LLM.

For this example, I asked ChatGPT to create:

A prompt for an outbound sales call for a realtor

The tone: empathetic and concise

Guardrails to keep the conversation professional

A goal to sell more properties from a list of 100 prospects

The AI produced a structured prompt that included:

A warm introduction

Questions to qualify the lead

Property categories to discuss

Closing steps to collect contact details

Step 2: Creating the Agent in VHO

On the VHO AI Voice Platform, I:

Created a new assistant using a basic template

Pasted my custom prompt into the script

Selected the voice (English for this demo)

Published the assistant

VHO also allows building agents in 40+ languages, integrating with calendars, CRMs, and payment systems.

Step 3: The Live Call Demo

Here’s how the outbound call went:

AI: “Hi, this is Alex from WeWork Real Estate Company. Is this a good time to talk?” Customer: “Yes.” AI: “We have some lovely properties available near your area. Would you like to hear about them?” Customer: “Sure, what do you have?” AI: “We have single-family homes, condos, and investment properties. What are you most interested in?” Customer: “A condo. How much?” AI: “Condos range from $200,000 to $600,000 in your area. I can send listings to your email or phone. Which do you prefer?”

The AI then collected the customer’s email, confirmed it, and promised to send the listings — all without human intervention.

Step 4: Improvements and Observations

The first test worked well, but I noted possible enhancements:

More concise responses to keep the call fast

Background noise simulation to make it sound more human

Maintain empathy without being overly wordy

Now imagine this system making 10,000 outbound calls in a single campaign — each one personalized, consistent, and able to answer property questions instantly.

Compliance Considerations

Always ensure:

You have the right to contact the leads

Your script complies with telemarketing laws

You disclose when AI is used (if required in your region)

Why This Is a Game-Changer for Real Estate

With the VHO platform, a single agent can:

Qualify leads before a human ever picks up the phone

Handle multiple calls simultaneously

Work in any language, 24/7

Automatically follow up with property details via email or SMS

This is the future of high-volume, high-quality real estate prospecting.
