When we talk about sustainability in real estate, we are talking about value stability and value enhancement. There are a number of factors that give a property promising prospects for the future: The location should have a good infrastructure – ideally with transport links, shopping, dining and leisure facilities as well as medical care, daycare/schools and the workplace within easy reach. The property itself is considered sustainable if the construction and living quality is right – this includes the planning concept with architecture and cut as well as contemporary construction, technology and equipment of the property. For example, energy-efficient construction as a KfW efficiency house, modern heating technology, innovative technologies (such as fiber-optic connection, SmartHome or e-charging station) and brand-name fittings contribute to long-term value retention.
