More than just a credit check
When selecting a tenant, there is more than meets the eye. You should do a credit check and a criminal background check. However, more often than not, the credit score may not be that great. Look further, see what caused that. If there was a prior eviction, then, of course, do not rent to them. If they did not pay their utilities, do not rent to them. However, if it is a credit card that was past due, see what it was all about. Sometimes the tenant has good character and made poor choices with their credit card.
