Property managers reviewing tenant apps

[Mike A.]

We have a few buildings that we do not manage directly, and the new property managers are managing them for us. Overall, they are doing a pretty good job so far. There have been a few applicants for the handful of vacant units, but they will not share the credit report with us citing privacy issues.  Some already have collections, but they will not inform us what they were about, other than they are considered small balances.  

How does one go about dealing with an issue like this? I've already requested for us to run the credit report, but they said we couldn't do that.
