Top 10 AI Cold Calling Tools for Off-Market Real Estate Deals in 2025

In 2025, real estate pros aren't just sticking to open houses and MLS listings anymore. Off-market properties—often called pocket listings—have become goldmines for agents and investors who want to get ahead of the game. But with tighter inventory and more competition, cold calling has gone from being a grind to a smart, AI-powered strategy. Here’s how Voice AI is changing the way we find hidden real estate gems.

Why Off-Market Properties Matter More Than Ever in 2025

The National Association of Realtors (NAR) says that off-market deals now make up about 10% to 20% of all real estate transactions. That’s a huge opportunity—worth an estimated $450 billion in 2025 alone. Here’s why these properties are a big deal:

• Less Competition: No bidding wars. No rush. Off-market properties are typically negotiated privately, reducing the stress and pressure of competitive offers.
• Faster Deals: Skip the wait for listings to go live. Many off-market deals close in less than half the time of traditional ones.
• Unique Finds: Access homes most people never even see. These might include inherited homes, distressed properties, or owners considering a quiet sale.
• Flexible Negotiations: With fewer parties involved, deals are more likely to be tailored to both the buyer’s and seller’s needs.

These factors are driving more investors and agents to find new, creative ways of sourcing these exclusive deals. And that’s where technology—and AI in particular—comes in.

Cold Calling Still Works—But It Needs a Smart Upgrade

Reaching out to property owners directly is still one of the fastest ways to uncover potential deals. But doing it the old-fashioned way is slow, inefficient, and costly:

• Manual cold calling = 30–50 calls a day, at best.
• Response rates? Often less than 10%.
• Cost per qualified lead? Around $300+ when you factor in time, labor, and missed opportunities.

Voice AI, however, is changing the game:

• It can handle 1,000+ calls a day without fatigue.
• Response rates increase by up to 3 times with personalized, human-like conversations.
• Cost per lead can drop below $50, making it far more scalable.

AI also ensures consistency. Every lead gets a prompt, professional call, even outside of traditional working hours. This constant outreach builds stronger pipelines and fills the top of your sales funnel faster.

Real Results: How Axis Homes Uses OpenMIC Voice AI

Axis Homes, a growing real estate firm in California, started using OpenMIC’s Voice AI agents in late 2024. They needed a solution that could scale outreach while reducing time spent on cold leads. In just six months, they saw:

• Over 200 calls a day handled by AI agents.
• A 25% increase in qualified leads, based on engagement and conversion data.
• A 40% drop in customer acquisition costs.

"OpenMic’s AI agents helped us uncover six off-market listings that became our top sales this quarter. The return on investment has been amazing," says Angela Lee, Lead Agent at Axis Homes.

Their secret? Letting AI handle the early-stage calls and filtering out uninterested sellers, so human agents only focused on warm, engaged prospects.

How to Use AI Cold Calling to Find Hidden Homes

Here’s a simple step-by-step process to get started with Voice AI in real estate:

1. Know What You’re Looking For

Define your target property profile: neighborhood, square footage, estimated value, owner profile (e.g., absentee, long-term owner), and potential sale triggers.

2. Set Up Your AI Caller

Choose your platform, upload your leads list, craft a few engaging scripts, and set your AI's working hours. Make sure the tone and language feel human, not robotic.

3. Review the Data

Track response rates, conversation length, call recordings, and transcripts. Use this to refine your message and segment hot vs. cold leads.

4. Follow Up and Close

Your AI tool should schedule follow-up calls, send automated texts, or alert your sales team when a lead shows strong intent. This keeps your pipeline active and responsive.

Emily’s Story: One Buyer’s Win with Voice AI

Emily, a 29-year-old entrepreneur from Austin, was looking for a fixer-upper in a good school district—a competitive niche in her area. She didn’t want to get into bidding wars or overpay, so she decided to try something different.

Using OpenMIC’s Voice AI:

• She scanned over 2,000 off-market homes using public records and demographic filters.
• The AI called 700+ homeowners with a personalized script.
• Within three weeks, she connected with a seller willing to negotiate privately.

"The AI was my secret weapon," Emily says. "It did the grunt work—called hundreds of people, filtered out the 'no's, and handed me the ones who were ready to talk."

Thanks to this approach, Emily purchased her dream home at below-market price—without a bidding war or listing competition.
