Tenant screening services are often employed by landlords to screen and evaluate potential tenants. After a tenant fills out a rental application form, a landlord may then use a tenant screening service to verify the information on the application and also obtain additional information about the applicant. Screening services may run background checks and gather credit history reports; they may also verify a prospective tenant's employment and reported income. Tenant screening services can obtain information on previous evictions, and also determine whether a prospective tenant has a criminal record. Landlords often use screening services to guard themselves against renting to high-risk tenants who could be a possible financial and legal burden to the landlord. Screening services are also used to determine the accuracy and truthfulness of the information provided in a rental application. Using a professional screening service can save a landlord time and energy, and the results of the reports obtained are guaranteed to be accurate.
