The short answer

An AI receptionist for commercial real estate brokers built on HighLevel Voice AI costs about $0.32 per answered call, or $29 a month for 90 calls averaging 4 minutes, phone line included. Roughly 23 of those calls (25%) would come outside office hours, which is where an AI answering service earns its keep. Emergencies, complaints and anything needing judgment should go to a person.

What the AI should handle

Qualify space inquiries

Asks the property type, square footage range, move-in date, budget and headcount, then books a tour or a call with the listing broker.

Send listing materials

Texts or emails the flyer and specs for the building the caller names, and notes that the broker will follow up on terms.

Book tours

Finds times on the broker's calendar that fit the building's access rules and texts the prospect the address and where to meet.

Take messages from cooperating brokers

Asks whether the caller is a broker, takes their client's requirements and contact details, and flags the message for the listing broker the same day.

What to send to a person

  • Rent, concessions and deal terms
  • Letters of intent and negotiations
  • Owner questions about valuation
  • Environmental, zoning or legal questions about a property

HighLevel's voice agents can transfer a live call, create a task, or trigger a workflow that texts the owner. Set the handoff rules before the agent goes live.

Cost per call and per month

Assumptions for a typical commercial brokerage: 90 calls a month answered by the AI, averaging 4 minutes. Phone minutes are billed per call and rounded up, so each call bills 4 phone minutes at $0.01165.

Compared with staff time

Those 90 calls take about 6 hours of talk time a month. At the US median receptionist wage of $18.27 an hour (May 2025, Bureau of Labor Statistics), that talk time alone is worth about $110, before hold time, breaks, benefits and the calls that come in after hours. An AI receptionist does not replace a good front desk; it catches the overflow and the evenings, and frees staff for the people in front of them.

Sample call

Example AI receptionist call for a commercial brokerageIllustration

AI AGENTThanks for calling Meridian Commercial. I'm the brokerage's virtual assistant. Are you calling about a property you saw?

CALLERYes, the flex building on Route 9. I need around 6,000 square feet for a small manufacturing shop.

AI AGENTThat building has a 6,200 square foot unit available with a dock door. When would you need to move in?

CALLERWithin six months.

AI AGENTThanks. I'll text you the flyer now. Alex is the listing broker and can walk you through it. Would Tuesday at 10 or Wednesday at 3 work for a tour?

CALLERWednesday at 3.

AI AGENTYou're booked for Wednesday at 3 at the Route 9 building. Alex will meet you at the front office and bring the rent and terms.

CALLERGreat, thanks.

Prompt tips

  1. Tip 1Load each listing's size, use type, power, loading, parking and zoning into the knowledge base, since commercial callers ask about specs before price.
  2. Tip 2Have the AI take the caller's company name and headcount, which helps the broker judge fit before committing to a tour.
  3. Tip 3Keep rent and concession talk with the broker by telling the AI to say terms are covered on the tour or call.

Rules to watch

Business calls still have limits. The FTC's Telemarketing Sales Rule exempts most business-to-business calls, but calls to cell phones using an autodialer, prerecorded message or AI voice still need consent under the FCC's TCPA rules. Many owners and decision makers answer on a mobile, so treat outbound AI calls as needing consent unless counsel says otherwise.

CAN-SPAM covers owner and tenant email. Market update emails to owners and tenants are commercial email, and the FTC says CAN-SPAM applies to business-to-business messages too. Each one needs an accurate sender, an honest subject line, a physical postal address and an opt-out honored within 10 business days.

Questions

How much does an AI receptionist cost for a commercial brokerage?
On HighLevel Voice AI, about $29 a month for 90 calls averaging 4 minutes, or $0.32 per answered call including the phone line. That is our estimate from HighLevel's published rates with a standard voice; premium voices cost more per minute.
Can an AI receptionist answer calls from property signs?
Yes. Voice AI can answer, give specs from the knowledge base, text the flyer and book a tour. Give each sign its own tracking number, at $1.15 a month for a local number, so you can see which signs produce calls. At 90 calls a month of four minutes, pay per use costs about $22 plus $4 in phone time before tokens.
Should the AI quote rent to callers?
Only when the asking rent is already public on the listing. Rent in commercial deals depends on term, concessions and improvements, so a number given without context can mislead. Have the AI say the broker covers terms on the tour or a call, then book that time.
Can the AI call owners for listing prospecting?
Outbound AI calls need prior express consent under the FCC's ruling on AI voices, and many owners answer on cell phones. Use outbound Voice AI for owners who asked to hear from you, such as those who requested a valuation, and keep cold prospecting as personal calls from the broker.
What happens when a cooperating broker calls?
The AI asks whether the caller is a broker, takes their client's requirements and contact details, and sends an urgent task to the listing broker. It can text the flyer right away. Terms and fee questions go to the listing broker, who handles them directly.
