This is not allowed in most leases, although, if allowed, one usually needs to get the written agreement of the landlord to ensure that any new tenant is credible. If one of the people visiting the premises is interested in renting the dwelling, an application for a tenancy should be submitted at that time in order to first verify their qualification as a tenant. A rental application is a document that requires details about the potential tenant`s current financial status (including income and creditworthiness), past tenancy agreements, and criminal history. The information is then analyzed to determine whether or not it is a valid candidate. (Typically, a fee is required for the tenant to offset the cost of processing the information.) Receipt of Agreement – The lease is not valid unless all parties have received and confirmed the lease. . . .
