Years ago I rented with a friend off a guy we knew while he went overseas. We had a proper lease and rented it furnished at market value. He wanted to rent it out furnished so he didnt have to get rid of all his stuff when he went travelling (he lived in the house before he went).
When he got back from overseas he randomly sent me an email one day and said he was back in Oz and coming round that weekend to pick up all his furniture so he could move into a new house. He seriously couldn't understand that he couldn't just come and take all the furniture when it was specified in the lease that we were renting it furnished. Also neither my friend or I were going to be in town that weekend so we couldn't even be there if he did come round.
I ended up basically having to tell him that if he let himself in the house or took anything I'd be calling the police. Such a freaking hassle. But also we were young and probably didnt handle it properly, it was the first time I had rented.
