Tenants are expected to pay rent promptly when due, and an alert manager will see that they are not permitted to get in arrears. A system of collections will include the mailing of bills in advance of the due date, calling on the tenants who do not remit by mail, personal letters asking for payment, notices to delinquents that an action will be taken against them, and finally a legal action itself. Of course, care and judgment must be exercised in dealing with tenants regarding unpaid rent. The agent should strive for a good record on his collections and a minimum of losses through bad debts, but should be careful not to antagonize a desirable tenant.
