The verdict in three sentences
A Miami brokerage receiving 900 inquiries per month from portals (Zillow, Realtor.com, Homes.com) finds about 70% unqualified, and its agents call back an average of 6 hours after contact. An AI qualification agent that asks prospects about budget, financing and timeline, then routes them to the right agent, costs EUR 10,000 to 25,000 (about USD 11,000 to 27,000) to set up and EUR 150 to 500 per month in API fees. First contact drops to 5 minutes, and agents only work solid leads.
Why speed and triage drive revenue
In South Florida, a serious buyer contacts 4 to 6 brokerages on average for the same type of property. The first one to respond relevantly gets the showing. A brokerage with 8 agents cannot call back 900 people per month: 30 inquiries a day, most of them browsers, out-of-budget requests or duplicates.
The AI agent replies by SMS, email or WhatsApp within 2 minutes, asks 5 to 7 questions (budget, down payment, mortgage pre-approval, primary or second home, timeline, property to sell), computes a score and creates the record in the CRM (Follow Up Boss, kvCORE, Lofty or HubSpot). Hot leads trigger an alert to the agent covering that area, warm ones enter a nurturing sequence.
| Metric | Without AI | With AI agent |
|---|---|---|
| Time to first contact | 6 h on average | 5 minutes, 24/7 |
| Inquiries handled by an agent | 100% | 30% (qualified only) |
| Showing appointment rate | 8% | 13 to 16% |
| Leads lost at weekends | About 25% | Under 5% |
| Sorting time per agent | 9 h/week | 2 h/week |
| Complete CRM records (budget, financing) | 35% | 90% |
These figures are 2026 orders of magnitude observed at brokerages with 5 to 15 agents.
Budget: setup and monthly costs
Cost depends on the number of channels, the depth of integration with the transaction software and how tailored the qualification script is (sales, long-term rentals, vacation rentals, luxury).
| Item | Essential version | Full version |
|---|---|---|
| Script and scoring design | EUR 2,500 | EUR 5,000 |
| AI agent (LLM, guardrails, memory) | EUR 4,000 | EUR 8,000 |
| Portal and real estate CRM connection | EUR 2,500 | EUR 7,000 |
| Channels (email, SMS, WhatsApp) | EUR 1,000 | EUR 3,000 |
| Dashboard and area-based routing | Included | EUR 2,000 |
| Total setup | EUR 10,000 | EUR 25,000 |
| AI API, SMS, WhatsApp, hosting | EUR 150/month | EUR 500/month |
In the US, SMS outreach must comply with the TCPA and 10DLC registration: the prospect must have opted in, and the agent must disclose that it is an automated assistant. Florida's privacy rules and fair housing law also require that scoring never uses protected characteristics.
Mini case study
Karim, managing broker of a 10-agent brokerage in Miami, receives 900 inquiries per month and closes 12 portal-sourced deals per month. Average commission: EUR 14,000 per transaction. With the AI agent (EUR 18,000 plus EUR 300 per month), the showing rate rises from 8% to 13%. Assuming stable showing to sale conversion, that means about 2 extra deals per quarter, or EUR 28,000 in commissions. Over the first year: EUR 112,000 in additional commissions for EUR 21,600 in total cost. Even if that assumption is halved, the investment pays back in under 6 months. Agents also get back 7 hours per week each.

FAQ
Does the AI agent replace real estate agents?
No. It sorts and prepares, the agent keeps the showing, the negotiation and the relationship. In our deployments, only 30% of inquiries reach a human, but with a complete record.
Do prospects accept talking to an AI?
Yes, when the reply is instant and useful: 60 to 75% answer at least 3 questions. The agent must introduce itself as the brokerage's assistant and offer a human at any time.
How long does deployment take?
Allow 5 to 8 weeks: 2 weeks scoping the script, 3 weeks of integration and 1 to 3 weeks testing on a pilot area before rollout.
Does it work with Follow Up Boss or kvCORE?
Yes, if the software exposes an API or automated import. Otherwise, a structured email bridge is possible, for about EUR 1,500 extra.
What do the AI calls really cost?
For 900 conversations per month, a major model's API costs EUR 40 to 120. The rest of the monthly budget covers SMS, WhatsApp and hosting.
