Best AI Calling Agents for Real Estate in 2026

The short version

Most “best AI calling agent” lists compare feature checklists. Feature lists are easy to write and impossible to verify. This one ranks on three things a buyer can check in ten minutes:

1. Does the vendor publish a price? If you must book a discovery call to learn whether a product is in budget, that is a cost.
2. What are the contract terms? Month-to-month, annual minimum, or enterprise-only.
3. Is it built for real estate, or is real estate one vertical of many?

Here is where the five land.

Three of the five publish complete pricing. Two do not.

1. AI IntelliCall — best for agents and small teams who want a price up front

Built for real estate specifically, and the plan price, the per-minute rate and the trial terms are all on the website. Solo is $497 a month for one agent or office. Agency Starter is $997 for up to three client accounts, and Agency Growth is $1,497 for up to ten. The agency tiers add a white-label dashboard and the ability to rebill minutes at your own margin. Voice is $0.23 a minute billed by the second, there is a 14-day free trial, and there is no contract.

Billing by the second rather than rounding up matters more than it sounds. A sixty-second qualifying call billed to the second costs $0.23; the same call rounded up to two minutes costs double.

Where it is not the right pick: if you are a developer who wants to assemble your own stack and keep per-minute cost at the floor, a component platform will be cheaper. And if what you actually want is a human picking up, this is the wrong category entirely.

2. Structurely — the established real estate name

Structurely has been in real estate lead conversion longer than most of this list and is the platform most agents have already heard of. It publishes usage rates — voice as low as $0.07 a minute, SMS as low as $0.02 a message, email as low as $0.02 — and meters usage in tokens.

What it does not publish is the platform fee. Its pricing page names a platform fee without stating an amount, and all three tiers (Small Team, Large Team, Enterprise) route to “Talk to Sales.” You cannot work out your monthly cost from the website.

Pick it if: you want the incumbent and don’t mind a sales process.

3. Retell AI — cheapest per minute, if you build it yourself

Retell is a developer platform, not a real estate product, and it is the most transparent on this list about component costs. Voice infrastructure is $0.055 a minute, text-to-speech from $0.015, telephony $0.015, and the language model anywhere from a fraction of a cent to $0.64 a minute depending which you choose. Phone numbers are $2.00 a month; concurrency beyond the first 20 slots is $8.00 a month each.

The headline “$0.07–$0.31 per minute” is real, but it is a range across components you assemble, not a price you are quoted. Two billing rules worth knowing, both published: silence and hold time are billed, and calls are tracked to the second with no per-call rounding. Failed calls are not billed.

Pick it if: you have a developer and want control. Skip it if: you want to be live this week.

4. Smith.ai — two products, and the difference matters

Smith.ai sells both an AI receptionist and a human-backed one, on separate pricing pages, and they are not close in price. Comparisons that quote only one of them get this badly wrong.

AI receptionist: Free at $0 a month for 25 calls, Pro from $150, Enterprise from $500, with call bundles from 75 up to 1,000 or more and overage from $2.10 to $3.00 a call.

Human-backed receptionist: $300 a month for 30 calls, $810 for 90, $2,100 for 300, with overage from $8.50 to $11.50 a call.

Both bill per call rather than per minute, which means a long call costs no more than a short one — the opposite of every per-minute platform here. If your calls run long, that is a genuine advantage.

Pick it if: you want per-call billing, or you want a person handling buyer calls and are comparing against the cost of a part-time ISA rather than against software.

5. Synthflow — enterprise only

Synthflow’s pricing page lists one plan, Enterprise, and states that “Enterprise contracts start at $30,000 annually.” No monthly cost, no included minutes, no per-minute rate. Final pricing is scoped by sales around call volume, concurrency, telephony, integrations, security and launch support.

Pick it if: you are a brokerage with a six-figure technology budget and a procurement process. For an individual agent or small team, the entry point rules it out.

How to choose in ten minutes

• Solo agent or small team, want a number today: AI IntelliCall, Retell, or Smith.ai’s AI tier.
• Calls that run long: Smith.ai, because per-call beats per-minute.
• Want the established real estate brand: Structurely, and budget for a sales call.
• Enterprise brokerage: Synthflow.

Whichever you shortlist, ask three questions before signing: is the rate billed by the second or rounded up; does the quoted rate include the language model and the voice, or are those extra; and can I hear a recorded call in my market, in my language, before I pay.

Frequently asked questions

What is the best AI calling agent for a solo real estate agent?

For a solo agent who wants a price before a sales call, AI IntelliCall publishes $497 a month plus $0.23 a minute with a 14-day trial and no contract. Smith.ai’s AI receptionist starts free for 25 calls a month. Retell can be cheaper per minute if you are willing to assemble and maintain the components yourself. Structurely and Synthflow do not publish a platform price.

Which of these platforms publish their pricing?

As of 22 October 2026, AI IntelliCall, Smith.ai and Retell AI publish complete pricing on their own sites. Structurely publishes usage rates but not its platform fee. Synthflow publishes only its $30,000 annual contract minimum.

Is per-call or per-minute billing better?

It depends on your average call length. Smith.ai bills per call, so a twelve-minute conversation costs the same as a two-minute one. Every other platform here bills per minute. Work out your own average before comparing headline rates — the two units are not interchangeable.

Do any of these handle Spanish for real estate?

Several support Spanish. The question that matters in South Florida is whether the agent switches language mid-call when the lead does, not whether Spanish appears on a feature list. Ask for a recorded bilingual call. More on bilingual AI calling.
