This is my first time renting property and don't know how to handle my exit inspection tomorrow.
I have cleaned the apartment thoroughly and will be leaving the place in arguably better condition than I found it. However, I had a moment of stupidity last month when i knocked a lit candle onto the wood floor and spilling the wax everywhere. I then proceeded to aggressively scrape it off. I marked the floor in doing so and the scratches, though faint, are noticeable.
I do not believe the landlord will attempt to fix or replace the floor considering it's condition was already sub-par prior to my tenancy and the damage i have done isn't as bad as some of the other marks already on the floor.
I want to be honest and let him know what I did but I'm worried that despite our good rapport, he'll use this to keep my deposit.
