Advance Payment (Rent)     This is most common method in foreign communities in Seoul. It requires advance payment of the total monthly rental for the entire lease term. The contract is usually signed for 2 to 3 years. No money is returned at expiration of the lease. But pre-paid rental is refundable prorata for the unexpired term of lease, if the lease is terminated prior to expiry date. One of the merits of this method is that the landlord is responsible for maintenance during the lease period. Rent does not include utility costs such as electricity, water, gas and heating.     Monthly Rental (Wolsei)     This is a deposit plus monthly payment system. The deposit amount is about 10 to 20 times the monthly payment. Usually 10% of the total amount is paid upfront when signing the contract and the remainder plus one month's rental is paid at the time of actual move. The amount deposited is returned to the tenant upon expiration of the lease. The tenant is responsible for maintenance.     Key Money Deposit (Chonsei)     About one-half to two-thirds of the value of the house is deposited with the Lessor for the lease period. The whole portion is returned to Lessee upon expiration of the lease. As with Wolsei, 10% of the total amount of rental is paid when the contract is signed, and the rest is paid when the lessee moves into the house. Common practice is that the Lessor is not responsible for maintenance. Accordingly, the Lessee is required to cope with all maintenance issues by himself unless otherwise provided in the pertinent lease contract. For example, replacement of curtains or re-papering of rooms will be on the Lessee's own expense. Another matter of this payment method is that the key money deposited to the Lessor will not be returned prior to the date of expiration of the lease unless a third party signs new lease contract replacing the existing one.
