What is a unit split percentage?
A unit split percentage is the share of a shared property expense assigned to each rental unit. For example, if one unit is responsible for 25% of the property, that unit would pay 25% of a shared utility bill.
Equal split vs square footage split
An equal split gives every unit the same percentage. A square footage split gives larger units a larger share based on their size.
When to use square footage
Square footage can be useful when units are different sizes, such as a basement apartment, main floor unit, and upper floor unit.
