3 – Is the owner of the property (Landlord) responsible for anything at all?

As the Landlord, you will need to make sure the exterior/structure of the building is sound. Stonish Properties is not liable for repairs to these parts of the buildings (e.g. roof tiles and structural condition). As a responsible landlord, you should make sure the building is insured with the appropriate HMO landlord product, and that you have adequate safety and environmental certificates in place (Gas Safety, Electrical Safety, EPC). You are responsibility to look after your own mortgage, if you have one.
