How much is the security hold with a debit card

To answer all of your question. If you do not have a round-trip ticket they will not rent to you. If you do, they will put a hold on the full estimated amount of the rental, once the car has been returned and paid for any money left will be credited back to your debit card, it is up to your financial institution when it shows back in your account. Better to use a credit card less hassle.

Take their insurance. I didn't have to put money down. They had a mustsng convert. waiting for me. I had a rock crack the front window. I paid cash after i got home. $250. So of thats a windshield. Take theres.
