VISALE is a free of charge, state sponsored guarantee scheme many employees of french companies are entitled to. If you are eligible to it, it is highly recommended that you apply to be ready to use if necessary.
Please remember however, it’s a guarantee scheme, and, as such, it is not compatible with unpaid-rent insurance plans. It can only be used for properties that are not covered by such insurance plans. Please note that most rental agents are not familiar with VISALE, which they often assimilate to previous state-sponsored guarantor schemes that left many liabilities unpaid, and many will reject it.
