Call Centre or AI for Real Estate Agents 2026: Answering Enquiries, Booking Viewings and What Telephone Prospecting May Do

In short: People who call about a property listing almost always want to know the same things: Is it still available, when can I see it, what does it cost? An AI voice agent can answer these calls, reply from the exposé and close with a viewing appointment, with EchoCall from €75 a month for 250 call minutes. A call centre staffed by people has the edge when conversations get difficult, for example with owners thinking of selling. Under German law, cold calling private individuals without their prior express consent is prohibited, whether a person or an AI makes the call.

We rewrote this post in October 2026. The old version claimed that agents lose an average of 30 per cent of their leads through unanswered calls and attributed this to an industry association. We found no source for it, so the figure and the calculation built on it are gone. Also wrong were appointment confirmations by text message, the number of languages and automated invitation calls for viewings as a ready-made feature. What is correct: confirmations by email and more than 30 languages.

Answering enquiries on property listings quickly

Every new listing brings the same wave of calls. Many of them are questions that are already in the exposé: year of construction, heating, energy certificate, service charges, pets. At the same time, the estate agent is often away from the desk exactly when the phone rings, because they are showing a property or sitting with an owner.

The problem is less the number of calls than their timing. An interested party who reaches nobody calls about the next property. An owner who is thinking of selling and lands on voicemail may never call back. What an AI agent actually does in an estate agency, with a sample call about a listing, is shown on our page on the AI phone assistant for real estate agents. This post covers the questions around it: call centre or AI, how viewing scheduling works, what the agent may say and what applies to telephone prospecting.

Which calls come into an estate agency and who should handle them

The rule of thumb: anything in the exposé or that fits into a calendar, the agent can do. Anything that needs negotiation, valuation or trust belongs with you.

Call script: how the agent handles a call about a listing

A good call script for estate agents is short. For the agent, you write it as an instruction in the prompt:

1. Greeting with AI notice. "Krämer Properties, good afternoon. You are speaking to our digital assistant. Which property are you calling about?"
2. Identify the property. By town, street or the reference number from the listing.
3. Answer questions from the exposé. Only what is in the knowledge base. If something is missing, the agent says so and notes the question.
4. Check the fit. For rentals the preferred move-in date, for sales the timeframe and whether financing has been discussed.
5. Offer a viewing. Free slots from the calendar, individual or group viewing, as you set it for the property.
6. Take contact details and confirm. Name, phone number, email address. The confirmation goes by email.

Coordinating viewings: individual or group

The agent books directly into Google Calendar, Outlook, Cal.com or Calendly. With Cal.com or Calendly you create a separate appointment type for each property, with duration, buffer time and number of places. That way you decide for each property:

• Individual viewings for properties for sale and high-end rentals, with a buffer for travel.
• Group viewings for rental flats with many enquiries, with a fixed number of places.
• Waiting list. When a slot is full, the agent adds interested parties to a Google Sheet. If someone cancels, you or your team call the next ones.

The agent confirms appointments by email via Gmail or SMTP, with the address and the contact person on site. It takes changes and cancellations on the phone and updates the calendar.

Pre-qualifying interested parties fairly

Pre-qualifying means asking the questions that really matter for the viewing. For rentals, the move-in date and the number of people. For sales, the timeframe and the state of financing. Income, employer and a tenant self-disclosure form do not belong in the first call. Collect those in writing when things get serious.

Be careful with filters that exclude people. Under the German General Equal Treatment Act, discrimination on grounds of race or ethnic origin is also prohibited in access to housing (§ 19(2) in conjunction with § 2(1) no. 8 AGG). [4] [5] So do not let the agent ask about origin or nationality, and do not give it rules that sort by name or accent. One advantage of the agent: it asks every caller the same questions in the same order.

Exposé, mandatory details and commission: what the agent may say

The agent only says what you give it. For correct answers, these points belong in the knowledge base:

• Mandatory energy certificate details. If an energy certificate exists, a property advertisement in commercial media must state the type of certificate, the final energy demand or consumption value and the main energy sources for heating, and for residential buildings also the year of construction and the efficiency class (§ 87 of the German Building Modernisation Act, formerly the Building Energy Act). [6] Callers often ask for these on the phone.
• Commission on a sale. If the estate agent is paid by both sides in the purchase of a flat or a detached house, both must commit to the same amount (§ 656c BGB). [7] A brokerage contract for the purchase of a flat or a detached house requires text form (§ 656a BGB). [8] So the AI agent states the commission as it appears in the exposé and does not conclude a brokerage contract on the phone.
• Commission on a rental. An estate agent may only charge the tenant a commission if they took on the mandate exclusively for that tenant (the "client pays" principle, § 2(1a) WoVermittG). [9] So for rentals, the AI agent should not bring up a tenant commission of its own accord.
• Distance selling. If a brokerage contract with a consumer is concluded only by phone or email, it is usually a distance contract (§ 312c BGB) with a right of withdrawal (§ 312g BGB). [10] [11] You send the contract and the withdrawal notice, not the AI agent.

Call centre or AI for real estate agents?

Some agents have their phone answered by an external phone service. The comparison on the points that matter in an estate agency:

For many agencies a mix makes most sense: the agent answers enquiries on listings and books viewings, and you talk to owners yourself. A calculation with real prices is in the post Call Center or AI Voice Agent? The 2026 Cost Comparison.

Telephone prospecting for estate agents: what is allowed

In brief: under German competition law, advertising calls to consumers are only allowed with their prior express consent (§ 7(2) no. 1 UWG). [1] A private owner who advertises their own flat is usually a consumer. Calling them to win a mandate is prohibited without consent, even if their number is in the listing. For businesses, at least presumed consent is enough. [1] Where consent exists, you must document it and keep it for five years (§ 7a UWG). [2]

The same applies to an AI agent as to a person or a call centre. A call script does not replace consent. The details, including Austria, Switzerland and other countries, are in the post AI Cold Calling in 2026.

If an owner who calls you asks for a callback, the agent records this in the call log.

Phone system and call forwarding in an estate agency

Your familiar number stays. In your phone system or on your mobile, you decide when calls go to the agent: when nobody answers after 20 seconds, when busy, outside office hours or during viewings. The codes for mobile phones are in the post Answering the Phone in the Trades 2026. Phone number and telephony are not included in the plan price.

For owners, banks and notaries, set up a transfer to your mobile. The agent then puts them straight through, as transfer to a phone number is a built-in tool.

What an AI agent costs for an estate agency

With EchoCall you pay for call minutes, about €0.30 per minute, with no setup fee. [3]

Work out your need like this: calls per day handled by the agent × minutes per call × working days. An example with assumptions: an agency with live portal listings forwards around five calls a day at three minutes each over 21 working days. That is 315 minutes, so the Basic plan with 500 minutes also absorbs the wave after a new listing.

Whether it pays off is a simple comparison. The Basic plan costs €1,800 a year. Assume one transaction brings your agency €8,000 in commission. Then a single extra mandate every four years, won through a call that would otherwise have been missed, is enough. Put in your own commission.

Connecting CRM and agency software

• HubSpot or Salesforce. The agent creates interested parties directly as a contact or lead, with property, timeframe and viewing appointment.
• Agency software. EchoCall offers no ready-made connection to a specific estate agency software. If your software has an interface, the agent can be connected via your own webhook, Zapier or Make.
• Notifications. Owner calls as a message in Slack or Microsoft Teams or as an email, so nobody misses them.

Setup in five steps

1. Try it without signing up. In the live demo you enter your website address. In about 20 seconds an agent is built from your public pages, which you can call in the browser or write to.
2. Create an account. In the EchoHub with 30 voice minutes and 30 chat conversations for 14 days, and the credit card is verified with €1.
3. Fill the knowledge base. Exposés as PDF, your property pages as URLs re-read at a fixed interval, plus office hours, commission rules and how a viewing works.
4. Set calendar and transfers. Appointment types per property, transfers for owners, banks and notaries.
5. Test. Call about two of your listings, move an appointment and play an owner who wants to sell. Wherever the agent becomes unsure, something is missing from the knowledge base.

Where the agent reaches its limits

• Valuations. It does not give a value for a property. You have the conversation with the owner.
• Negotiations. Price reductions, offers and commission questions beyond the exposé go to you.
• Properties not in the knowledge base. Remove sold and let properties promptly, or the agent will offer viewings for something that no longer exists.

Data protection and AI disclosure

Since 2 August 2026, callers in the EU must be told that they are talking to an AI (Article 50 AI Act). [12] For the phone agent, you write the notice into the first sentence yourself, and the editor in the EchoHub reminds you with an info box. More on this in EU AI Act 2026: What the AI Disclosure Duty Means for Voice and Chat Systems.

For a viewing, the agent needs name, phone number and email address. EchoCall's servers are in data centres in Frankfurt and Karlsruhe. You will find the data processing agreement at echocall.de/avv, and the technical and organisational measures and subprocessors in the Trust Center.

Frequently asked questions

Call centre or AI: which fits real estate agents better?

For enquiries on listings and booking viewings, an AI agent fits well, because it answers from the exposé and books directly into your calendar. For conversations with owners, valuations and negotiations, a person has the edge. Many agencies combine both.

What does an AI phone assistant cost for an estate agency?

With EchoCall from €75 a month for 250 call minutes, about €0.30 per minute, with no setup fee. Phone number and telephony come on top. An agency with live listings often manages with the Basic plan for 500 minutes.

May an estate agent prospect private owners by phone?

In Germany only with their prior express consent (§ 7 UWG). That applies even if the owner has published their number in a listing, and it applies equally to people, call centres and AI agents. You must document the consent.

Can the agent book viewing appointments?

Yes. It books directly into Google Calendar, Outlook, Cal.com or Calendly, as an individual or group viewing as you set it for each property, and confirms by email. It also takes cancellations and changes.

Can the agent connect to our estate agency software?

It connects directly to HubSpot and Salesforce. For other agency software there is no ready-made connection, but there is the route via your own webhook, Zapier or Make if your software has an interface.

Do callers notice that they are talking to an AI?

Yes. The AI Act has required the notice since August 2026, and the agent says so in its first sentence. Anyone who would rather speak to a person is transferred or called back.
