First, we take a large (3,4,5-bedroom) but not very liquid object, and remake it into a more liquid one: we lease by the room.
Second, we develop a stylish design and furnish it at our own expense. We know for a fact that rooms with our design are in demand and we can lease them at a higher price.
Third, we are a service to both owners and tenants. Our tenants get extra 'perks' like regular cleaning, household chores, and no commissions. Owners enjoy a stable passive income without downtime, search for tenants, apartment maintenance, and unpleasant surprises.
