📌 Introduction — Real estate is a game of timing
Hello from the ElevenLabs Lab.
In the real estate industry, phone calls have two defining traits:
First, every inquiry is high-value — a single call can lead to a significant commission.
Second, it’s notoriously difficult to answer every call — you’re constantly out for property viewings, showings, or closings.
Bridging this gap is the quintessential use case for an AI voice agent. While our first post (Dental & Medical) focused on inbound backup, this real estate edition covers both inbound and outbound (batch calling) workflows.
📖 Quick glossary for clarity ⚡
• Lead = A potential client who has yet to sign a contract. One inquiry call typically equals one lead.
• Inbound = Calls coming into your agency; Outbound = Calls you make to initiate contact.
• Batch Calling = A feature where you upload a contact list (CSV/Excel) and the AI calls each person automatically.
• Knowledge Base = The digital guidebook you provide to your AI. Upload your current listings, and the AI will reference them to answer prospect questions.
• Tool Call = The AI’s ability to "listen" to the conversation and directly update your records with client information.
• CRM = Your "Customer Relationship Management" system. Whether you use Salesforce, HubSpot, or a specialized database, this is your central hub for tracking client data.
🏠 1. What your AI agent can do for your agency
Listing-based Q&A — Upload your property list (prices, square footage, move-in dates) as a document or URL, and the AI will use it as the source of truth.
As of April 2026, we’ve introduced source citation, allowing the AI to reference specific documents for its answers (per official release notes).After-hours lead capture — Don’t let night-owl buyers go to voicemail. The AI engages them, gathers contact details, assesses interest levels, and notes their budget.
CRM Auto-logging (Tool Calls) — Extract lead data from the conversation and push it directly into CRMs like Salesforce or HubSpot.
ElevenAgents offers native integration plus API/webhook support (see official documentation).Outbound Batch Calling — Upload your list via CSV/XLS and insert variables like names or property titles for a personalized touch.
Supports immediate or scheduled calls with real-time progress monitoring. Perfect for client check-ins or new listing alerts.Multilingual support — Communicate in 31 languages with automatic language detection. This is a game-changer for agencies serving international tenants or investors.
💡 ElevenLabs’ vertical-specific pages highlight outcomes like "3–5x more meetings in the first month" and "60–70% reduction in cost-per-lead." Official case studies include Better (lending) reporting a "2x lead-to-lock conversion rate" and Cars24 achieving a "35% improvement in conversion."
These are company-reported metrics; we recommend setting conservative expectations and validating performance in your own agency first.
💰 2. Cost simulation — Outbound adds up fast
Official pricing (as of June 2026): Creator $22/mo (includes 275 minutes) / Pro $99/mo (includes 1,238 minutes), with $0.080/min overage.
LLM token usage and telephony costs (e.g., Twilio/SIP) are billed separately. Please note that wait times and no-answers are still billed as duration (per official Help Center).
Scenario | Monthly Volume | Plan Required | Est. Monthly (Agent fees only) |
|---|---|---|---|
Inbound Backup only | 520 min | Creator $22 + (245 min × $0.08) | ~$42 |
Inbound + Weekly Batch | ~1,720 min | Pro $99 + (482 min × $0.08) | ~$138 |
▲ Calculations based on list rates. LLM tokens and telephony fees are extra. Outbound calls are billed even if there's no answer, so high-quality lead lists are key to cost efficiency.
⚔️ 3. Competitive landscape — Vapi / Retell / Bland
Vapi, Retell, and Bland are major global AI voice platforms. They provide professional-grade telecom automation services, allowing you to build highly customized, bespoke solutions compared to standard "AI Secretary" services. ⚡
Based on 2026 comparative research (softcery.com):
Platform | Base Price | Real-world Total/Min | Best For |
|---|---|---|---|
ElevenAgents | $0.08–0.10 | $0.08–0.10 + LLM | All-in-one + Natural voice + 31 languages (No-code friendly) |
Vapi | $0.05 (Orchestration) | $0.23–0.33 | Developer-focused (Manual STT/LLM/TTS setup) |
Retell AI | $0.07~ | $0.07–0.31 | Call center focus (HIPAA compliance strengths) |
Bland AI | $0.11–0.14 | $0.11–0.14 | High-volume outbound sales |

In short — If you’re a real estate office looking for a plug-and-play solution without a dedicated dev team, ElevenAgents is the most efficient choice. If you have in-house engineers and prefer to mix and match infrastructure components, Vapi may be better suited for your needs. If you’re managing a massive outbound sales organization, Bland AI is optimized for that scale. Note that while Vapi’s $0.05 base price looks attractive, third-party measurements show the total cost often climbs to $0.23–0.33/min when factoring in the full tech stack.

⚠️ 4. Before you launch (Regional considerations)
Phone Numbers — Regulatory constraints can affect local number provisioning via Twilio. For inbound office lines, check with your local carrier regarding SIP trunking options (see the 4th section of our first post for details).
Outbound Compliance — While our US-based documentation focuses on TCPA compliance and DNC filtering, please ensure you adhere to regional regulations regarding telemarketing and opt-in requirements. Starting with existing clients or warm leads is always the safest approach.
Language Performance — Quality can vary across languages. We recommend using the free plan to test your own property scripts and verify the naturalness of the output.
Start Small — Begin by automating "After-hours and Missed Inbound" calls. Monitor call logs to refine the experience and expand the agent's responsibilities gradually.
🚀 Wrapping up
In real estate, the core value of an AI voice agent isn't to "replace people," but to "ensure your office stays productive while you’re out in the field."
