When you rent a car from Avis in 2026, the company typically places an authorization hold on your credit card that equals the estimated cost of the rental plus a minimum of $250. If you choose the "Pay Now" option, the hold is often reduced to just the $250 security deposit. For luxury vehicles or rentals at specific high-demand locations, this hold can be significantly higher, sometimes reaching $500 or more. If you use a debit card, the rules are often stricter: Avis may require proof of a return flight and will immediately deduct the hold amount from your bank balance. Once you return the car in good condition, Avis releases the hold, but it can take 3 to 14 business days for your bank to reflect the funds back in your available balance. It is a "pro-tip" to ensure your credit limit can accommodate this "frozen" amount so you don't accidentally decline other transactions during your trip.
