When signing the rental agreement, most rental companies will request a security deposit (credit hold). The amount requested, however, varies and will depend on the vehicle´s category and rental period as well as on the rental company itself.
This amount will not be charged. Instead, it will only be put on hold, constituting a warranty for the rental company. The hold will be removed upon request of the rental company once you return the vehicle. Should the hold have been placed on a credit card, the wait-time for the hold removal to take effect will depend on your card´s operator.
