Editorial note. This guide is aimed at both owners about to list a €2M+ asset and investors looking to buy. It is not an advert for LuxeAI. It is an operational checklist that any honest broker will recognise as reasonable. If a broker reads it and feels attacked, that probably confirms the red flags we list.
Why €2M is the threshold
Below €2M, a generalist agency can manage the asset with good results: there is reasonably liquid demand, buyers accept public portals and a standard process, and the commission absorbs the cost of conventional marketing.
From €2M upwards everything changes:
- International buyer in >70% of cases, with expectations of multilingual service, full dossier in their language, and a discreet process.
- Longer cycle (3-9 months to close) and more failed visits if pre-qualification is weak.
- Differentiated marketing: drone video, Matterport virtual tour, dossier in 3+ languages, possible off-market.
- Higher regulatory risk: AML compliance (anti-money laundering), KYC on the buyer, more demanding due diligence, cross-border taxation.
- High opportunity cost: every month a property sits overpriced on the market costs property tax, community fees, maintenance and brand degradation of the asset itself.
Checklist: 12 questions to evaluate an agent
Ask them in order. If on any of the first 5 the broker gets defensive or evasive, drop them.
1. How many >€2M deals have you closed in the last 24 months, with verifiable references?
Valid answers are "X deals, I'll send you 2-3 references with the owner's permission." Invalid ones are "many, but for confidentiality reasons I can't say anything." Confidentiality protects identities, NOT the fact of having operated.
2. What percentage of the buyers who closed did so within 6 months of the first visit?
Good brokers in this niche convert 40-55% in 4-6 months. If they tell you "everything closes in 2 months," they lie or sell cheap assets. If they say "12-18 months is normal," either their marketing is weak or their buyer book isn't at the right level.
3. What digital tools do you use to qualify leads, and what is your average speed-to-lead?
Good: WhatsApp Business with response under 30 minutes, CRM (HubSpot, Pipedrive, Apimo), web form with qualification, from 2025 onwards AI qualification in the lead's own language. Red flags: "I reply when I can," "I use email, it works fine."
4. Which languages do you operate in, and are they native or assisted?
For the Costa del Sol, ES + EN native is the minimum. Desirable: ES + EN + RU + DE + FR depending on the asset. If they say "I work in 8 languages" but it's one person, ask how. The valid answer is "I have a team + assisted translation + native review for the dossier," not "I use Google Translate."
5. What % of your business comes through your own digital channel (web, social, paid) vs third-party channel (portals, referrals)?
Boutique brokers in this niche should have 40-60% own channel. If everything comes via Idealista Pro / Lucas Fox / referrals, they're a lead reseller, not an operator.
6. What kind of exclusive listing do you propose, for how long and with what exit terms?
Reasonable exclusive: 4-6 months, with a 90-day review, possibility of exit if a minimum activity threshold is not met (X visits / Y qualified leads / Z paid campaigns invested). Owner-breach penalty clause only on long exclusives with high justified paid investment. Red flags: exclusive > 12 months, no activity metric, disproportionate penalties at first rejection.
7. How does your marketing proposal translate into a concrete budget with verifiable deliverables?
I want to see: "€X in Meta Ads + €Y in LinkedIn Ads + €Z in audiovisual production (drone, Matterport) + €W in multilingual dossier + €V in accredited-broker open house." And a calendar. If the broker says "I'll do strong marketing" with no breakdown, there is no proposal.
8. How do you qualify the buyer before a visit?
Expected: signed buyer file under NDA, funds verification (not necessarily the amount but origin and availability), motivation, timing. For assets > €5M, formal KYC before visit is standard. Red flags: "anyone can visit, that's how we make friends with the buyer." No, that's how you expose your asset to tourists.
9. What discretion policy do you keep? Do you publish identifiable exterior photos?
For €2-5M, careful exterior photography is reasonable. For €5M+, it depends on the asset and the area. In La Zagaleta, identifiable exterior photos are simply unacceptable. In Sierra Blanca or Golden Mile it depends on the owner. The good broker raises this BEFORE; you decide.
10. Do you comply with AML (anti-money laundering) regulations and GDPR?
Direct question: "are you registered with SEPBLAC?" (the Spanish AML executive service). It is mandatory. "Do you have a written GDPR policy and a named DPO?" Also mandatory for any company handling client data on operations >€10M per year.
11. How do you manage the offer and due diligence phase?
Expected: coordinated management with the owner's lawyer, the buyer's lawyer, tax advisor, land registry, and notary. The broker should NOT be the sole intermediary in due diligence — that is legal work. But they should coordinate the calendar and milestones, ensuring nothing falls through due to lack of communication.
12. What commission do you charge and to whom?
Costa del Sol market €2-10M: 3-5% on the final sale price, normally split between the buyer-side and seller-side broker if there are two. Minimums €60-150K per deal. Red flags: aggressive variable commission (10%+) without justification, or hidden double commission (charging the owner and the buyer without telling either).
Additional red flags
- "I have a buyer for your house" without the owner having signed anything. It's the classic formula to get in and then collect commission without having done real marketing.
- Pressure to sign exclusive at the first meeting. Any serious broker lets you decide for 48-72h.
- Doesn't show you their website or social channels live. If they can't show you traffic, leads and public case studies, they don't have them.
- Price promise without valuation. "Your house is worth €4.5M" without a written valuation is sales hot air. Demand a written valuation or comparable.
- "I have exclusive contact with the prince of X". If a broker boasts about a specific client, they usually don't have them or lost them years ago.
The new factor: an agent with AI properly applied
From 2025 onwards, the good brokers in this niche are incorporating:
- 24/7 multilingual AI concierge that qualifies before the broker calls.
- Automated multilingual dossier in 30 minutes instead of 3-5 days.
- Intent scoring over web behaviour + WhatsApp conversations.
- Owner dashboard with real, transparent metrics.
This does NOT replace the broker. It frees them from operational tasks so they can dedicate time to what they charge for: human relationship of trust, negotiation, due-diligence coordination.
If the broker you're evaluating tells you "I don't use AI, I work by hand," it's legitimate on €500K properties. It's worrying on €5M properties, because it means they operate with 2018's timing and languages.

Conclusion
Selling a €2M+ property is a project, not a transaction. The agent you choose determines 60-70% of the outcome — final price, time to close, buyer quality, legal complications avoided.
One hour of interview with 3-4 candidates and the checklist above saves 6-12 months of bad advice. It is not trivial. It is the most profitable investment you can make before putting up a single sign.
LuxeAI is not an agent. We build the AI layer that good agents use to become even better. If you are a broker and want to work this niche with technology that respects your brand, let's talk.
