Outsourcing real estate management in the Netherlands has evolved over time, with investors initially handling management in-house but later outsourcing property management tasks. The relationship between investors and managers is strained due to low profit margins and perceived subpar services.

The study aims to identify opportunities for real estate management organizations to strengthen their market position. Key findings include increased professionalization of real estate management organizations, challenges in investor-manager relationships, and potential for improvement in services provided by managers.
