How do you split utilities in a rent-by-the-room house?
Splitting bills evenly causes friction when room sizes vary or someone works from home all day, while formulas based on room size or occupant count require upfront agreement and constant recalculation when tenants move. Factoring utilities into the rent removes monthly math and arguments, but leaves you vulnerable to absorbing the risk of high seasonal bills like winter heating.
