Proprium is a real estate expertise and advisory brand that helps property owners generate liquidity from their assets while exploring ways to retain use or ownership rights. It offers several tailored solutions, including occupied and vacant life annuities, bare-ownership sales, mortgage credit, reverse mortgages, property sale-and-leaseback arrangements, and lifetime leases. Depending on the solution, owners may receive a lump sum, ongoing income, or financing linked to their property’s value, with terms designed around their circumstances and goals.

Proprium guides clients through each stage of a project: understanding their needs, assessing the property’s value, preparing a personalized study of suitable options, and arranging the release of funds through a formal deed with the involvement and supervision of a notary. The company also provides online simulators for exploring selected property transactions and financing scenarios. Its stated approach emphasizes expert support and customized solutions, helping owners consider alternatives to selling outright while making use of the value held in their real estate.
