Is some bad credit ok?

[Richard Bader]

I would like to get some opinions from experienced investors with rentals. When you run a credit check and criminal background check, what is acceptable? Am I correct in assuming that the majority of people renting are going to have some type of bad credit. If I have an applicant that has a verifiable job but has some type of bad credit. What are the warning signs? What do you feel is acceptable as far as credit and criminal checks? Also it is ok to call and verify an applicants employment, right?
Thank You,
Richard
