Trust in real opinions
How can I acquire a property as an investment?
With Cosona, the path to a high-yield property investment is simple, structured and transparent. In a personal consultation, we first determine your individual goals and requirements. Based on this, we present you with carefully screened properties that are the perfect fit for your investment strategy.
As soon as you have made your decision, we will reliably guide you through the entire purchase process - from financial advice to the signing of the notarised contract. Our verified property values and our personal, comprehensive service ensure that your investment is not only secure, but also retains its value in the long term.
Can I buy a property for my own use?
Cosona specialises in properties as capital investments that offer long-term income and value appreciation. Our properties are therefore primarily designed for investors and capital investors. However, if you are interested in a property for your own use, we can offer you individual advice and help you find the best option for your needs. Talk to us - together we will find a solution that suits you.
What makes Cosona a reliable partner for property investments?
Cosona checks every property in accordance with a strict, internal company code to ensure that only properties that have been checked and are of lasting value are offered. With the Cosona concept, you invest in properties that generate long-term returns thanks to many years of experience, innovative approaches and sustainable concepts. In addition, we guarantee transparent, secure and partnership-based cooperation throughout the entire management period of your investment, so that you can rely on trust and security in your investments.
What advantages does Cosona offer me as a consultant?
As a property consultant, you benefit from a strong and trusting partnership with Cosona. We provide you with carefully vetted properties that you can recommend to your clients as secure investments. Through our in-depth expertise and transparent communication, we create the trust that encourages your clients to make long-term, repeat investments with you. In addition, we actively support you in the advisory and sales process, offering attractive partnership models and customised solutions to efficiently optimise the entire sales process.
How does Cosona support external property developers and other real estate agents in marketing their properties?
Cosona pursues a clear strategy based on its own defined standards and processes. We therefore do not offer direct support in the marketing of properties from external property developers or other real estate agents. Our focus is on the careful selection, inspection, refurbishment and management of properties, which we offer in accordance with our high quality standards and sustainable concepts. We cannot and do not wish to vouch for the product and process quality of properties that fall outside our own standards.
