Leasing Company not disclosing information

[Sam Abe]

Hi! We hired a company to rent our place only for leasing and we will manage once it is rented. 

They are not disclosing information needed to approve the tenant. For example they are just saying the credit score is above 650. They are not disclosing proof of income. How can we approve if we can't see the information. 

They claim it is private information and can't be disclosed. Then how do we decide if we should rent to the potential tenant and not just rely on their review.
