People Background Check is now becoming commonplace. In times past, landlords and property managers would rent based of appearance and "gut feeling" and nothing else. The landlord would place an ad in the local paper and the first clean cut person that showed up to see the rental was approved.
Landlords are becoming more sophisticated and taking advantage of companies that offer Tenant Background Check. They have learned the hard way through their pocket book that doing a complete People Background Check is not just a good idea, but is mandatory in today's marketplace.
