The Lease Buyer would be responsible for any termination charges at lease end.
The Lease Buyer is assuming the remainder of an in-process lease, and will be responsible for the lease-end terms as included in the original lease contract.
Lease-end charges may include disposition fees, excess mileage fees and excess wear & tear assessments. All potential lease-end charges will be outlined in the original lease document.
However a Lease Buyer can negotiate with the Lease Seller on a cash incentive to take over the auto lease, which can then be applied against any fees or charges related to the lease at the Lease Buyers discretion.
