ACCENTRO Real Estate AG is the market leader in housing privatization in Germany. A large part of the customer base is made up of private investors who purchase properties from ACCENTRO as an investment. Such investments are associated with important metrics. For example, real estate is compared based on location, market price, possible return and price development. Excel tables are often used for this, but maintaining and creating them is laborious and error-prone. For this reason, there was a need for a more efficient software solution to this problem. A clear real estate comparison site should be created for private investors. In collaboration with the Cheil agency, we poured the requirements into an intuitive web application called PropRate.
