A well-known axiom says "those who do not remember the past are doomed to repeat it." A landlord that doesn't check a potential tenant's credit report is destined to renting to someone they shouldn't have. For this reason landlords ought to require credit checks on potential tenants. Landlords can pay six figures for the house that they will lease to people. Before you give the keys of your six figure investment over to a renter, shouldn't you at least be aware of something concerning the person who is going to be residing in your property?
