For us, a management mandate goes far beyond simply renting your property – we really take care of your assets. This is how we put at your disposal a fully dedicated and experienced team that will ensure optimized management of your buildings, apartments, villas and exceptional properties. 

Manage your assets differently

Delivering excellence in management since 1950, m3 GÉRANCE has all the expertise to inform you of market movements and advise you on opportunities to enhance your assets.

Our multidisciplinary approach allows us to offer you the gamut of services far wider than most traditional management providers: Administrative management, financial management, legal advice, technical maintenance, restoration works, energy optimization, secure 24/7 online access to your client account…

Our approach

Managing your assets also means ensuring the sustainability of their value. The professionals at m3 GÉRANCE master all aspects that affect the conservation of a building. They daily work closely and harmoniously with tenants, owners and concierges. The technical supervision of each building allows us to undertake optimization work and thus avoid any energy drift.

Building a relationship of trust

Confidentiality, ethics, responsibility and professionalism. More than words, these values are for us the foundations of a lasting relationship.

Our managers (administrative and technical), accountants and teams that make up m3 GÉRANCE intervene on your behalf and act as interfaces with the various stakeholders by paying special attention to listening, dialogue and responsiveness.
