Three conversations, then access.

01

Introduction

A 30-minute call. We learn your situation, you assess our fit. No materials shared.

02

Due diligence

Banker reference or KYC documentation. Required by the sellers we represent, not us.

03

Access

Curated dossier of matching residences sent privately. Viewings arranged on a per-asset basis.

Editorial

Why these owners don't list publicly.

Discretion comes first. Divorce settlements, inheritance liquidation, reputational caution, relocation under time pressure — the reasons a Marbella owner refuses a public listing are usually the reasons they also refuse a brochure, a video walkthrough, or even an address before the buyer is verified.

Many of these sellers value the right buyer over the highest bid. A long-tenured neighbour, a buyer with discretion of their own, an acceptable use of the property — all weigh more heavily than a 5% premium from an unknown bidder. The sale is negotiated through us precisely because price is not the only term in play.

And quietly: there is no advertising tax. No portal-driven price discovery dragging the asking down with every week of inventory. No agents at three other firms calling the same buyer. The transaction is built around the asset, not around the marketing campaign.

The best Marbella addresses change hands at restaurants, not on Idealista.

04 / Questions

Six things buyers always ask.

Frequently asked
How is the Private Collection different from your public listings?
Public listings are the residences sellers want marketed broadly — portal exposure, photography, price discovery. The Private Collection is the opposite: owners who refuse portal exposure for reasons of discretion, timing, or family circumstance. The seller chooses the buyer rather than the highest bidder. Smaller universe, longer review process, materially different access conditions.
What due diligence do you require?
A KYC pack: identity verification, source-of-funds confirmation, and either a banker reference letter or recent statement evidencing capacity at the relevant range. This is not bureaucracy on our side — sellers themselves require it before any dossier or address is released. For purchases above €10M, a personal introduction from existing counsel or a known intermediary substitutes in most cases.
Can I see a sample dossier before applying?
No. The dossiers are the asset — sharing one publicly defeats the purpose of the collection. What we can share on a call: the structure of a typical dossier (10-18 pages, full media, ownership history, legal status, pricing rationale, sample comparable transactions), and the categories of properties currently under review. The dossier itself is shared only after due diligence completes.
Is there a buyer-side fee?
No. We are paid by the seller's side at completion, on the same commission basis as a public-listed sale. Buyer-side representation costs the buyer nothing additional — and crucially, our incentive to negotiate hard on the buyer's behalf does not compete with our remuneration. Where buyer-side advisory mandates exist (extremely rare, only on bespoke €25M+ briefs), we agree fee structure in writing before any work begins.
How long is the access pipeline?
From first call to first dossier: typically 7-14 days. The bottleneck is due diligence — KYC review on our side takes 48-72 hours once documents arrive, but obtaining a banker letter or recent statements from your side can add a week or two depending on jurisdiction. Active buyers with documentation already prepared can be reviewing the first dossier within 5 days of the introductory call.
What if I'm already represented by another agency?
If you have an exclusive buyer-side mandate signed with another firm, we cannot represent you on Private Collection assets — the sellers we work for refuse multi-agency exposure. If you are working informally with other agents (no signed mandate), that is workable: most Private Collection buyers come into the process with multiple agent relationships, and the sellers care about who introduces the buyer, not who else the buyer has spoken to. Disclose existing relationships on the introductory call and we will tell you immediately whether we can proceed.
