Tenant credit score: do you average or take individual?

[Daniel K.]

How do you maintain a minimum credit requirement for tenant applicants applying to the same unit (IE a SFH)? Do you require that everyone applying individually meet the requirements of the limit, or do you average the score?

I would hate to lose good tenants that meet the 650 minimum requirement, just because they are bringing an adult child with them who lacks a credit history.  Yet strictly adhering to the requirements protects you from being sued for discrimination.
