Exclusive real estate model gains traction

Arnaux Viallaneix has built an independent real estate advisory business since 2024, using a 100% exclusive model that avoids cold calling. He reports a steady influx of significant mandates, an improved portfolio, and clients who refer him or entrust him with new sales.

Background in real estate leadership

Before becoming independent, Viallaneix held roles such as commercial and marketing director in major real estate firms, where he led a transaction team involving around 500 collaborators. In those roles, exclusive mandates consistently outperformed standard ones in conversion rates.

Focus on Paris and Île-de-France

Viallaneix’s business is concentrated in Paris and the Île-de-France region, particularly the western part of Paris, with some exceptions in the provinces. Though affiliated with a network, he operates independently and does not delegate mandates to other advisors.

Exclusive mandate structure and responsibilities

Clients choose Viallaneix personally, as he handles their files, meets buyers, and manages the sale until the notarized deed. This model suits an independent professional aiming for full control. The exclusivity allows him to invest in the property’s presentation, including pre-ad publication expenses, which he bears if the sale fails.

Customized property analysis and enhancements

Viallaneix starts with a detailed assessment of the property, including past sales, competition, and potential objections. He uses automated tools for analysis and integrates additional services like architectural consultations or energy improvement studies, depending on the property’s needs.

Professional presentation and marketing

He employs high-quality tools such as professional photography, virtual tours with drones, and detailed reports to showcase properties. Marketing efforts include targeted portals, social media campaigns, and an interactive digital sale when appropriate, all aimed at attracting informed buyers.

Client trust and international standards

Viallaneix maintains a consistent level of service throughout the sale, which is crucial for international clients, especially those from Anglo-Saxon backgrounds, who expect precise communication. He also collaborates with notaries, maintaining a dedicated data room for documents to ensure smooth legal processes.

Word-of-mouth and network growth

Approximately 90% of Viallaneix’s new mandates come from client or prospect recommendations. He also receives referrals from service providers and maintains visibility through regular publications, especially on LinkedIn. These efforts have led to significant sales, including exclusive mandates worth over 7 million euros.

Performance and selectivity

By mid-October 2026, Viallaneix had signed over 30 million euros in new mandates for the year, with an average value exceeding 1.5 million euros. He has not had any failed transactions before the notarized signature and has become more selective, avoiding mandates that do not align with his standards.
