Frequently asked questions
How should roommates split rent for unequal rooms?
Weight shares by room size, private bathroom, and light: bigger or ensuite rooms pay more. Agree the shares once in writing, then reuse them every month.
What is the fairest way to split utilities?
Split flat utilities evenly, and usage-based costs like groceries by actual consumption. Keep one shared note of who paid what so settling up takes minutes.
How do we handle a guest or partner staying over?
Agree a threshold upfront, like more than seven nights means chipping in on utilities. Clear rules beat awkward conversations every time.
