Apologies - I thought you were looking to tag rent as an expense (e.g. a purchase invoice).
If you’re looking to basically see a breakdown of income vs expenses for individual properties (assuming you’re not an agent), then you may want to take a look at project tags, and have one for each property. This would also allow you to create a P&L report for each tag.
Your bank statement on QuickFile should ideally reflect your true bank statement where possible, so any income or outgoings should be tagged to the relevant invoices from there.
I hope this helps?
