Based on Household Income and Family Size
Your rent is based on household income and on your family size.
The net income of the highest earning tenant is used first to calculate rent. It is usually a fifth of this income with reductions called allowances for the number and age of dependants in the household.
Income from other adults in the household is taken into account for rent purposes.
Your rent is adjusted if there is a decrease or increase in income.
