The background check will search an applicant's background based on police and governmental databases.
The credit check will search the Equifax credit bureau to return the credit score, which is a numerical value that determines how responsible the applicant is with credit that is given to them. This is a soft check and it will not impact your credit score.
The checks are completed under the landlord’s discretion.
Background checks and credit checks are performed by a third party service called Certn.
