Calificasa is the only independent online platform in Spain where both private individuals and professionals can apply for a Legality Label. This label was developed from the experiences of over 10,000 buyers and homeowners. Over five years, real-life cases were collected and refined in collaboration with ethical lawyers and architects. Thanks to this close cooperation, we understand better than anyone how to help buyers safely realize their dream of owning a home. It’s no coincidence that we’ve been accepted into the *Centro Europeo de Empresas e Innovación* – the European Center for Innovation in Spain. While energy labels have long been mandatory, there were until recently no standard guidelines for property due diligence. By introducing the Legality Label, we help prevent misunderstandings and bad purchases.
