A real estate AI agent that actually qualifies leads, books viewings, and writes back to your CRM costs €900–€8,000 to build and 4–8 weeks to ship. A simple FAQ widget is cheaper and basically useless. The difference is the whole point of this article.
Here's the problem every Warsaw agency I talk to has: an Otodom or OLX inquiry lands at 22:40, the agent sees it at 9:15 the next morning, and by then the buyer has already messaged three other listings. Responding within five minutes makes you roughly 100x more likely to actually connect with that lead. Nobody on your team is awake at 22:40. An AI agent is.
What an AI agent is — and what it is NOT
Most "real estate chatbots" you've seen are decision trees: press 1 for sales, press 2 for rentals. They capture a name and a phone number and then sit there. That's a lead-capture form with a face.
An AI agent is a different animal. It runs on a large language model with retrieval over your actual listings and knowledge base (RAG), so it answers from your data, not generic fluff. It holds a real conversation, decides what to ask next, and then takes actions — creating a CRM record, booking a slot in the agent's calendar, escalating a hot lead to a human.
- Chatbot: "Leave your number, an agent will call you." Conversion to qualified lead: low single digits.
- AI agent: "You're looking at 60–75 m² in Mokotów up to 1.2M zł — I have three matching listings and the owner of the Puławska one is free Thursday at 18:00. Want me to book it?" Conversion: meaningfully higher because the lead is advanced, not just captured.
If a vendor sells you a "chatbot" and means the first one, you've bought a toy. The funnel only works when the system can act.
Concrete use cases for a Warsaw agency
This is what I build the agent to do, in priority order:
- 24/7 lead qualification. Budget, district, property type, buy vs. rent, timeline, financing readiness. The agent asks the same questions your best agent would, scores the lead, and tags it.
- Instant replies to portal inquiries. New message from Otodom or OLX gets a contextual answer in under a minute — pulling the right listing details, not a canned template.
- Booking viewings. The agent checks the agent's calendar, offers real slots, confirms, and sends a reminder. No phone tag.
- Buyer–listing matching. Given the buyer's criteria, it surfaces the 2–3 listings from your inventory that actually fit, instead of dumping the whole catalogue.
- Multilingual handling. Warsaw is PL / EN / UA / RU. The agent detects the language and replies natively in all four. You don't hire four receptionists.
- CRM integration. Everything lands in Asari, EstiCRM, HubSpot, Pipedrive — whatever you run — with the conversation, the score, and the next action attached.
The agent doesn't replace your closers. It handles the first line so the people who close deals only ever talk to leads worth their time.
What it costs to build
Honest ranges for the Warsaw / Polish market, one-time build:
Starter agent — €900–€1,500
Website + one portal channel (Otodom or OLX). Lead qualification, language detection, CRM write to one system. Ships in ~4 weeks. Good for a single-office agency testing the water.
Standard agent — €2,000–€4,000
Multiple channels (website, WhatsApp, Otodom, OLX), full PL/EN/UA/RU, viewing booking against a real calendar, buyer–listing matching, CRM with lead scoring and handoff rules. 5–7 weeks. This is what most agencies actually need.
Custom / multi-office — €5,000–€8,000
Multi-branch routing, deeper CRM logic, voice channel, analytics dashboards, custom matching on your own inventory rules. 6–8 weeks and up.
On top of the build there's a running cost: roughly €50–€200/month — LLM API usage, hosting, and the channel/CRM connectors. That scales with conversation volume, not with headcount. I'll quote it flat before we start.
If you only ever see "€40/user/month" SaaS pricing online, that's a rented generic tool. A build is yours, integrated into your CRM and your listings — which is the difference between a demo and a system that moves your numbers. I cover the full scope on my AI agents service page.
The ROI math (do this before you commit)
Don't buy on vibes. Run the numbers:
- Inquiries you get per month outside working hours: N
- Of those, the share that currently goes cold before anyone replies: typically 50–80%
- Your average commission per closed deal: C
- Realistic conversion lift from instant, qualified follow-up
If you get 200 inquiries a month, half arrive after hours, and recovering even a handful of otherwise-dead leads closes one extra deal a quarter, a Warsaw commission usually pays back the entire build inside the first year — often the first few months. The agent works nights, weekends, and the two weeks your best agent is on holiday.
What data the agent needs from you
The build goes fast when you bring these. It stalls when you don't:
- Current listings — a feed or export (the agent matches and quotes from this)
- Your qualification questions — what your best agent actually asks
- CRM access — which system, and a sandbox/API key
- Calendar — for viewing booking (Google Calendar / your CRM's calendar)
- Handoff rules — when does a lead get pushed to a human, and to whom
- Tone + FAQs — how you talk, plus the 20 questions buyers always ask
- Languages — confirm PL/EN/UA/RU or whichever subset
That's it. I handle the model, the RAG, the connectors, and the testing.
What I do and charge
I build production AI agents end to end — no no-code template you'll outgrow in a month. You get:
- A 30-minute discovery call, then a fixed quote with a start date within 24 hours.
- Build in 4–8 weeks depending on scope, with a working demo on your real listings before launch.
- CRM + portal integration done properly, not faked with email forwarding.
- 30 days of post-launch tuning included — because the first weeks of real conversations are where you sharpen it.
Pricing is fixed before we start. No surprise add-ons mid-project.
FAQ
Is an AI agent just a fancy chatbot? No. A chatbot captures a name and number from a script. An AI agent understands natural language, answers from your real listings, qualifies the buyer through conversation, and takes actions — booking viewings and writing to your CRM. The difference shows up directly in conversion rates.
How long does it take to build? A starter agent ships in about 4 weeks. A standard multilingual agent with booking and CRM integration is 5–7 weeks. Multi-office custom builds run 6–8 weeks. You'll see a working demo on your own listings before launch.
Can it really handle Polish, English, Ukrainian and Russian? Yes — modern LLMs handle all four natively. The agent detects the inquiry language and replies in it. For a Warsaw agency that's a serious edge: you serve UA and RU buyers without hiring extra staff.
Will it connect to Otodom and OLX? It replies to inquiries that come from those portals — usually via your inbox or CRM where those leads land — with full listing context, in under a minute. Direct portal API access depends on what each portal exposes, so I confirm the cleanest path during discovery.
Does it integrate with my CRM? Yes. Asari, EstiCRM, HubSpot, Pipedrive, or a custom system — the agent writes the conversation, the lead score, and the next action into your CRM so nothing gets re-typed and nothing gets lost.
What does it cost to run each month? Roughly €50–€200/month for LLM usage, hosting, and connectors, depending on conversation volume. It scales with traffic, not with how many agents you employ — which is the whole economic point.
Will it replace my agents? No, and it shouldn't. It handles the first line — qualifying, answering, booking — so your closers spend their time on leads that are actually ready. The deals still get closed by people.
If you run a Warsaw agency and you're tired of after-hours inquiries going cold, let's talk. Book a 30-minute call and within 24 hours you'll have a fixed quote and a clear plan for your AI agent.
