Many landlords choose to screen potential tenants before entering into a rental agreement. They may call a tenant's current employer to verify employment information, and speak to previous landlords to gain information about the tenant's rental history. Landlords may even obtain credit reports and check court records and criminal databases when screening tenants. Landlords screen tenants to determine the risk involved in renting to a particular person. For example, a person with a history of eviction due to nonpayment of rent may be regarded as a high risk tenant, and a landlord may choose to deny that tenant's rental application. Other landlords may choose not to rent to those who have been convicted of certain criminal offenses due to the risk involved. Screening tenants is not illegal, though the Fair Credit Reporting Act allows tenants some rights when it comes to tenant screening. A tenant may be able to request that a landlord divulge the nature of the information obtained in the tenant screen that led to a denied rental application.
