To obtain a zero-interest loan, you must first verify your eligibility and that your project qualifies. To apply, please contact our support service for further details. When compiling your application, you will need to provide information about your personal circumstances (identity, income) and submit supporting documents (identity card, family record book, payslip). You will also need to specify your request with all the details concerning your real estate project (new or existing property, the land, the building zone). Finally, you will also need to provide the necessary documentation to demonstrate that this project aims to acquire your primary residence (rent receipts for the last two years or a certificate of free accommodation).
