This is currently under development and at the moment it is a log only. You will need to edit the tenant at the appropriate time to change the rent amount manually.
We will be changing this to download a rent increase form and automatically adjust the rent in the tenancy record soon.
If you adjust the rent, these can be logged under the rent adjustment tab located at the bottom of a tenancy record.
After clicking on the tab, you can add a new rent adjustment and enter the information presented.
