We moved out of an apartment after staying there for 6 years. We had rented it out from an agency and they were pretty strict! They had the entire apartment painted (a part of the cost has to be borne by us), got the bedroom parquets replaced and polished. One bedroom had light scratches but that was not acceptable according to them. They also replaced the hand shower as it had a small chip. These were among other things. We have handed over the claim to the insurance and are yet to hear from them.
So what we took away from this experience was to take preventive measures to protect the walls, floors, kitchen counter tops etc. You may invest in some magic erasers for the walls, cover the floors with carpet to prevent dents and scratches coming on them etc. etc etc.. These are all the more important if you have kids and pets.
