I used to have a bunch of residential rentals.
We had very clear standards to qualify. Either you meet/exceed the standards, or you don't.

If not, a co-signer was required.

The basics: Income must be at least three times the monthly rent, and nothing in active collections.

If a potential resident had good credit, but was a bit short of 3x income, we would allow a co-signer.

The standards must be black and white, no wiggle room, same for all.
Otherwise, we are guilty of discrimination.
