Multiple Security Deposits Down On A Lease, How Does It Work?

[Lexdiamonds]

I have heard many people say that you can put up to 9 security deposits down on a lease for lexus and they refund the money at the end of the lease. This will lower your payment by almost a $100 a month. how does this work and is it a good idea if you have the 4 or 5k to do it. I was reading in another forum that a member leased a new ES350 with 5k out of pocket (3500 is refundable and the other 1500 is the fees) and is paying a little over $400 a month.
