Real Estate

Real estate companies, which use specialized company law structures – usually Special Purpose Vehicles without equity – have the difficult job of meeting the demands of stakeholders, such as city administrations. Here, too, bond insurance can provide the necessary protection.

Specialist products for the real-estate industry:

payment guarantees

development guarantees, e.g. for schools, kindergartens, or similar obligations

Sureties based on estate agent and property developer regulations (MaBV)

Rent deposit sureties

§650f BGB (German Civil Law) sureties

We are well acquainted with real estate companies and their structures. We count some of the biggest players in the industry among our clients. But we are also happy to find suitable sureties for smaller housing associations and property management companies. We can give you a no-obligation consultation.
