Expertise Meets Innovation

EverEstate is the digital platform of the ZIEGERT Group for real estate brokerage for private buyers and investors. The specially developed platform moves the entire real estate purchase process online, and creates full transparency over all products and steps, from the search to financing and calculation of rates of return, and offers the highest user comfort.

The aim of EverEstate is to make buying property more efficient and customer-friendly. The platform combines the ZIEGERT Group’s 30 years of proven expertise in the real estate business with innovative digital solutions, and makes the services offered more transparent and effective. Through optimising the administrative processes, EverEstate creates more space for personal customer care and individual consulting services. At the same time, digitised process control makes it possible to tailor our services even more closely to the needs of the customer.

With this digital process, bringing the offline world of real estate online, EverEstate is setting new standards for real estate purchases.
