Due Diligence is described in the dictionary as "the care that a prudent person might be expected to exercise in the examination and evaluation of risks affecting a business transaction." In other words, it is up to a landlord to do his or her own Due Diligence before renting to a prospective tenant.
Due Diligence on the part of a landlord can be comprised of a few different things. Landlords will almost always run a credit check on the tenant to make sure they pay their bills on time. They will also run a background and eviction check for that extra bit of Due Diligence.
If you are a landlord you should do your Due Diligence at YouCheckCredit.com so you don't end up with a tenant that doesn't pay the rent or possibly is a drug dealer in disguise.
