A landlord friend of mine rented a property to a bloke on benefits, the bloke came home one night drunk and tripped on a crack in the path to the house(or so he claimed) he then sued my friend for compensation.
Any one thinking of becoming a landlord should be aware that as owner of the rented property your tenant can sue you if they are injured on your property. because the landlord is responsible for the maintenance of the property if your tenant trips and falls downstairs due to a loose floorboard or whatever you can be held liable.
You just get landlords liability insurance
