In Rentables you can schedule a rent increase to automatically update in the future. This way you can set it in the system at the same time you send the tenant their notice. Auto charge will use the new amount and your management fee will update automatically (for percentage based PM fees).
Schedule a Rent Increase (or Decrease)
Go to the Property Details page (or Lease Details). From the Lease action menu, select Schedule Rent Increase.
Enter the Effective Date for the increase (or decrease) and enter the new amount. When finished be sure to click the Add button.
