The South Carolina monthly lease allows a tenant to occupy a particular residential property without a set termination date for a monthly fee. The contract expires for an indefinite period until one of the parties, landlords or tenants, gives the other a written statement of its intention to terminate the contract. A monthly lease should be treated in the same way as a standard lease for residential buildings. The lessor should check the creditworthiness and context of the potential tenant through a rental application form. In addition. Within thirty (30) days of termination of the rental agreement, a landlord must return to the tenant a deposit and a list of deductions, if any. A tenant must communicate in writing to the landlord the details of his new address or redirection, otherwise he may lose his deposit. .
