The investor. An existing property owner who sells a share of their home to the Resident Owner and keeps the rest as a passive co-owner — earning an index-linked return with none of the work, cost or stress of being a landlord. Think of it as an index fund for housing.
The Passive Owner already owns a property — a long-term landlord, a downsizer, or a family member — and wants property exposure without the operational burden. Rather than selling the whole home or renting it out, they sell a partial share to the Resident Owner for cash and retain the balance.
In return for the Resident Owner's sole occupancy, the Passive Owner receives an occupancy fee, and their capital tracks the regional property index quarter by quarter. They keep most of the upside of property ownership while shedding the bottom slice of risk to the Resident Owner's equity — and they have no tenancy, no maintenance, and no vacancy to manage.
