As the owner, you set the price of the security deposit. On average, we recommend that the owner charge  between $500 - $1500 for the security deposit as this will help cover any costs that may arise from damages, extra mileage, or closeout charges.
If both owner and renter are happy with the trip and no additional charges are added the renter will receive their full deposit back as soon as the closeout process is done on the website.
