Can I make all the repairs to my rental?

[Hunter Eidmann]

Hello everyone! I’ve been binging everything BP for the past month and have a accumulated laundry list of questions to ask. My first questions is what repairs am I allowed to make to a property I just bought and plan to rent? I am assuming everything except gas but I am unsure and can’t find an answer on google. Also, do the rules change if I am living in one side and renting out the other? Do the rules also change if I am just an owner occupier with no tenant? Lastly, do the rules change if I am no longer living in the house and it is just the tenants? Thank you so much for you help!
