I would definitely not rent out to someone who did not have enough for the deposit. My daughter rented out her flat to a young lady, who seemed to be the perfect tenant - big mistake - she ended up disappearing with a lot of the items from the flat after she had been using the place almost as a brothel. She had loads of extra keys made and was giving them out to various other "ladies" and a print out of the phone bill showed many numbers who all seemed to have knowledge of the flat. The only way to go to get recompense was a) the deposit, and b) a small claims court case which daddy ended up paying for her before it ended in court, probably because he did not want the embarrassment of it being made public.
