But if I am right then you can look at the net income of a lower income tenant and not the gross.Given the above, I use the following guidelines.based on net.... if net income is 3000 then multiply it by .40 and the rent they can afford is 1200 (they can afford 40% of net)based on gross.....if gross income is 4000. then multiply by .30 and the rent they can afford is 1200 (they can afford 30% of gross)Keep in mind I am not sure if 3,000 per month is low income.
