In Geneva an application is won or lost on the file you hand in. Expect to provide a copy of your passport or ID card and your residence permit, your last three payslips or, if you are self-employed, your latest tax assessment, an extract from the debt collection register (extrait du registre des poursuites) less than three months old, proof of third-party liability insurance and the agency's completed application form. References from a previous landlord help, and as a rule the rent should not exceed a third of your gross income. We review your dossier before it is submitted so nothing is missing.
