The real estate market in Germany is primarily a rental market; the ownership rate is far below the European average. At the same time, rents continue to rise, especially in the major cities. In order to enable more people to finance their own property, GroupEstate offers a comprehensive planning and organisation tool for property purchases within the Group. 
GroupEstate solves several problems of buying real estate together: On the one hand, we offer a platform to find group members and to inspire them for their own purchase project. On the other hand, we help to give the buyer group a legal form in which each member enjoys legal security and can easily apply for a group loan.

By pooling their resources, groups can use GroupEstate to finance their property at better conditions and use more capital.

GroupEstate also offers free group administration, financial calculator, property search, sample contracts and financing offers for families, friends or crowdfunding groups. In this way, we lower the barriers to participation in the real estate market and create solutions for building, buying and living within the group.
