If you want to do a revenue share with the owner this is nothing to do with Airbnb @Rose2635 - you would need to agree how payments are made and utilities covered .
presumably as you are suggesting this to the owner you will have a contract to cover the arrangement.
before you take on further properties I would suggest you address the issues leading to poor reviews at a number of your properties for issues such as cleanliness .
airbnb can suspend hosts that fall lower than 4.6 and you have a number of properties that are lower than this . If you don't address the issues they can ban you from the platform.
