Hi @Jackie_Howe
It sounds to me like Project Tags are the way to go.
Project tags can be used to to keep things grouped together (e.g. expenses for a property) you can find more information here: Projects in QuickFile
In your case you could have a project tag for “tenant address”, then bills and other expenses can also have that tag meaning you can see everything in the same place.
You can also generate a profit and loss for each tag which in your case could show the total bills compared to the rent received.
