In Denmark – just like many other countries – you can either rent or buy a home. In Denmark there is also a special form of housing called the “condominium apartment” or “housing cooperative” (Danish: andelsbolig). This housing type can be considered to be something between renting and ownership. You buy a share in a building, then pay a monthly housing fee, which is used by the condominium association (Danish: andelsboligforening) for expenses such as interest payments, repairs and upgrades.
