What I need to know on 328i or 428i lease?

So I am planning to work on finalizing a deal this week on a executive demo. Here is what I think I know so far and what I need to know. Please feel free to chime in.

I am not a returning BMW owner so I will need to put down a security deposit, but can add MSD up to a total of 8 to lower the money factor.

Minimum money factor before MSF is .00134. (Is that correct)
What are current residuals for 10k/12k/15k?
Mileage Discount of residual value is Mileage - 500 x $0.25

Based on other comments, 20% off MSRP is goal for a 2016 Executive Demo.

Anything I have missed or need to know? Thanks in advance.
