I'm considering an auto lease swap, for which the online sites (swapalease, leasetrader) have info on the number of months remaining and cost per month etc. However, after some research I realized that many cars are quite distant and need to be shipped with insurance. There is also more confusing terminology of requiring a down payment (does this reduce monthly payments or its in addition?) and apparently some fees for using the websites.
What are the other costs involved in lease transfer, and how do I estimate the total expenditure? I understand that some things like shipping are variable, but hopefully there are ways to get a ballpark estimate.
