Anything expense incurred to make your rental income can be added, provided you have the receipts.

Personal expenses refers to expenses that weren’t incurred to make income. For example, if you are only renting out part of your home, and you put new curtains in your own bedroom, this would be a personal expense. If you put new curtains in the enter house, including the rented out part, you would only include the expenses for the rented out part, not the rest of the house.
