how do I add a security deposit AFTER the reservation has been accepted

[Donna15]

@Mayra1, you can edit your listing. Click on 'edit', then go into the menu in the left-hand column and select 'pricing'. Scroll down, and you will see where to add a security deposit.  However, it will not apply to the current reservation, only to the next ones.

You can't change a contract once it has been accepted by both parties.
