I have a property that I'm thinking of renting out, could anyone tell me what happens when the RTB tells you to sort out issues in the house. For instance, I can't feasibly install ventilation, the house is 500 years old. It also doesn't have a banister on one side of the stairs. These are things that letting agents have pointed out but I'm a bit unsure as to whether they'll actually kick up much of a fuss about them and what power/resources they have to do about it. My mother lived there for 35 years with no issues, it's a grand house.
