Tenant screening requirements question

[Edlyn Gonzales]

We have an application for one of our apartments with 2 tenants. Our minimum requirement for credit score is 580. 1 of the applicants credit score is 558 (this person makes majority of the income) and the 2nd person has a 661 credit score. Should the 580 minimum be an average of there scores? Or per person? 

Based on the employment records the jobs thst afford them the apartment are new. And one of them has a DUI. 

What else should we be considering ?

Would you accept this couple as a tenant? Why or why not?

Thank you!
