Lexikon: down-payment (Mietsonderzahlung)
This special rental or leasing surcharge is a down payment on the purchase price of the car and is due before the start of the leasing contract. This down payment reduces the amount to be financed and thus also the monthly leasing rate. As a result the leasing company considers this as additional security since process of redemption corresponds to the value of the car leased earlier.
Under certain circumstances this down payment may be tax-free for commercial lessees (please ask your tax advisor).
In the case of leasing contracts for private individuals a down payment is usually included in the conditions of the contract.
