Tenant credit check question

[Sam Leon]

I require an individual application for each adult occupant of the rental unit.

Now, do you all run a credit / background / eviction / reference check on all applicants or only the one responsible for the rent?

For example a 2 bed room unit with a male/female but the male is the one I am signing the lease with (which include the female as an occupant) do you credit check both or just the one paying rent?
