Returning deposits: Are invoices needed?

[Marek Kucharski]

Hello Everyone, 

My tenants have recently moved out, leaving the house in less than ideal condition. The condition of some walls went beyond normal wear and tear and the house in general was left quite dirty. I decided to clean the house myself (1 full day, house + windows) and the painting and garden cleanup took another 2 days.  Can I deduct my labor from their deposit or should I have hired people to do all this so that I had receipts as proof.  I have photographic documentation of what needed to be done, but I did the work myself. Can I provide my tenants with an itemized list of deductions (fair value) or do I need actual invoices from gardeners, cleaners etc.? 

Thank you for your help.
