In Switzerland, two-thirds of the population live in a Rental apartment. The apartment belongs to the landlord or landlady, who does not occupy it himself. The people who use the apartment are called tenants. They rent the apartment and pay a rent for it, usually monthly.
Only one third of the resident population lives in a Condominium or a own house. There is a reason for this: apartments and houses are very expensive in Switzerland; most people cannot afford them.
Renting out apartments involves some effort, as does the maintenance of the property. Many landlords therefore hand over this work to a Property Management. This is then the contact point and responsible for the tenants' concerns.
