All pending/settlement statuses relate to your bank account that we set up within the system.
This includes Refunds, which may be confusing. The Refund settlement date is just the date that the funds clear your account. So when you issue a refund, it should leave your account that day or the next day, and the settlement date for the refund will reflect that.
We do not have any data for when the funds will actually hit the tenant's bank account (or whoever you are refunding).
This depends on their bank, the hold days on your account, along with other factors.
