I don't have pets - I'm not able to commit to 10+ years of being able to look after them, so I don't have them. This isn't due to renting, but due to me being bored with places easily.
I can paint the walls, put up pictures (Berlin has better rules than UK/Australia). Not that I do when I can.
I've only been evicted a couple of times, and even then I wanted to move anyway so it was convenient. It's usually me/us moving on and the landlord annoyed that they have to find a new tenant.
And don't forget the wonderful bonus of anything that goes wrong being someone else's problem. Roof leaking? Phone the landlord. Rising damp? Phone the landlord. Mold problems? Neighbours building a new fence? Frost damage to the pathway? Pipes frozen? Window cracked? All not my problem.
